Highlights
- Preoperative assessments in Turkey typically include medical history reviews, vital sign checks, and specific tests like blood counts, ECGs, or kidney function tests based on the patient's health and surgery complexity.
- Clinical teams follow protocols similar to NICE guidelines, ensuring that investigations are selected based on individual risk factors rather than performing every test automatically for every patient.
- The final decision to proceed with the operation rests with the surgeon and anaesthetist after reviewing all test results and confirming safety measures upon the patient's arrival.
If you are travelling from the UK for an operation, you may be wondering what tests are done before surgery in Turkey and what happens when you reach the hospital. Blood tests, an ECG, an anaesthetic assessment and sometimes imaging may be part of the process, but not every patient needs the same investigations. Knowing what is likely—and what depends on your health—can make your treatment journey easier to plan.

This guide explains the preoperative checks commonly discussed for international patients, why your hospital might request additional tests and what to ask before leaving home.
What tests are done before surgery in Turkey?
For an elective operation, the preoperative assessment typically begins with your medical history, medications, allergies, previous operations and anaesthetic experiences, followed by basic checks such as blood pressure, pulse and oxygen levels. The clinical team then chooses any investigations that are relevant to the planned surgery and your individual risks.
Potential investigations include a full blood count (FBC), kidney function and electrolyte tests, blood glucose, ECG (heart tracing), coagulation tests, pregnancy testing where applicable, and imaging or specialist reviews when indicated. Some patients will need fewer tests; others need a much more detailed work-up.
The UK National Institute for Health and Care Excellence (NICE) guideline NG45 advises that testing be selected according to the complexity of surgery and the patient’s health, rather than automatically requesting every available investigation. This is useful guidance for understanding the clinical rationale, although individual hospitals in Turkey operate under their own applicable standards and protocols.
A preoperative review is not a guarantee that the operation will go ahead. The operating surgeon and anaesthesia team must still decide whether proceeding is appropriate based on the full assessment.
What happens when you arrive at the hospital?
The exact sequence depends on whether you have already completed some tests at home, whether you are being admitted the evening before or on the day of surgery, and the arrangements made by your treating hospital.
- Registration and confirmation: Staff check your identity, planned procedure, records and necessary admission documents.
- Nursing assessment: You may be asked about recent illness, allergies, medication, supplements, smoking, previous anaesthesia and any new symptoms since your original consultation.
- Vital signs: Blood pressure, pulse, temperature, oxygen saturation and height or weight may be checked.
- Clinically indicated investigations: Blood samples, an ECG or another test may be completed or reviewed if required for your case.
- Surgeon and anaesthetist review: The teams confirm the treatment plan, assess relevant risks and check whether more information is needed.
- Final safety checks: Consent, the procedure and treatment site, fasting instructions and other safety measures are confirmed before surgery.
Some steps may take place during an earlier pre-admission appointment or by video or telephone before travel. The Royal College of Anaesthetists’ perioperative guidance recommends assessment early enough to address medical concerns before the day of an elective operation.

Blood tests before surgery: what does each one check?
Blood tests are among the most familiar parts of preoperative assessment, particularly for major operations. However, a small outpatient procedure may require few or no routine blood tests in an otherwise healthy adult.
Full blood count (FBC or CBC)
A full blood count measures haemoglobin, white blood cells and platelets. It can help identify anaemia, certain blood-count abnormalities and issues that may require further investigation. Low haemoglobin can matter when the planned operation involves meaningful blood loss or when anaesthesia and recovery risks are being assessed.
NICE recommends an FBC for adults undergoing major or complex elective surgery, but not routinely for every healthy patient having minor or intermediate surgery. A normal blood count does not by itself prove that an operation is safe.
Kidney function and electrolytes
Tests such as creatinine, estimated glomerular filtration rate (eGFR), sodium and potassium help assess kidney function and the body’s salt balance. They may be useful for patients with kidney disease, diabetes, certain medications, dehydration risk or more extensive surgery.
These results can influence fluid management, medication decisions and whether additional assessment is needed. NICE makes kidney testing more likely as surgical complexity and certain medical risks increase; it is not mandatory for every minor operation.
Blood glucose and HbA1c
A blood glucose test shows the amount of sugar circulating at the time of testing. HbA1c provides an indication of average glucose control over the preceding months. These measurements may be particularly relevant for patients with diabetes or suspected abnormal glucose regulation.
NICE recommends offering HbA1c testing to people with known diabetes if they have not had it checked within the previous three months, while advising against routine HbA1c testing solely for surgery in people without diagnosed diabetes. Hospitals may use other clinically justified protocols depending on the patient’s assessment.
Clotting tests (PT, INR and aPTT)
Coagulation tests assess selected parts of the blood-clotting process. They may be requested if you have a bleeding disorder, a history of unusual bleeding, certain liver conditions or take medications that affect clotting.
They are not routinely recommended for all healthy adults. In particular, a normal INR does not establish that all anticoagulant medicines are absent or that bleeding risk is zero. Tell the team about blood thinners and any previous unexplained surgical bleeding. Do not stop prescribed medication without instructions from your clinicians.
Liver function, iron studies and other tests
Depending on your history, the surgeon or anaesthetist may request liver blood tests, iron or ferritin measurements, nutritional markers or other investigations. These are selective tests rather than an identical panel for all international patients.
For example, a person with significant recent weight loss, a restrictive diet or a history of nutritional problems may need a different assessment from someone in good health preparing for a brief procedure.
Is an ECG required before surgery in Turkey?
An electrocardiogram (ECG or EKG) records the electrical activity of the heart using small electrodes placed on the skin. It is generally quick and painless. It may reveal rhythm abnormalities or other findings that warrant discussion before anaesthesia.
An ECG is commonly considered for people with certain cardiovascular conditions, diabetes or other relevant risks and for more complex procedures. However, being booked for an operation in Turkey does not mean that every otherwise healthy young patient needs an ECG.
In the NICE NG45 recommendations, ECG testing is generally not routine for healthy patients undergoing minor or intermediate elective surgery. For major or complex surgery, recommendations vary by medical condition and age. Your hospital may have specific requirements, which should be explained to you in advance.
Depending on your symptoms and history, an abnormal ECG can prompt cardiology review, a change in the anaesthetic plan or a delay for further evaluation. A normal ECG is reassuring in context but does not rule out every heart condition.
Will I have an ultrasound before surgery?
Not necessarily. An ultrasound uses sound waves to create images of organs or tissues. Whether it is useful depends on the type of operation and the question your doctor needs answered.
For example, an abdominal ultrasound might be considered before certain abdominal or bariatric operations if symptoms, examination or the local surgical protocol justify it. A pelvic ultrasound may be relevant for a specific gynaecological concern. These are not universal screening tests for every plastic, dental or weight-loss surgery patient.
There is also an important difference between an ultrasound of the abdomen and an echocardiogram, which is an ultrasound examination of the heart. The latter is usually reserved for appropriate cardiovascular indications. NICE advises against routinely offering an echocardiogram before surgery and suggests considering it for symptoms or signs that indicate potential heart failure or certain symptomatic heart murmurs.
If your coordinator mentions an “ultrasound”, ask which body area will be scanned and why. The name of the test alone does not tell you what the team is checking.
Do you need a chest X-ray or lung tests?
A chest X-ray can help investigate selected chest or lung concerns, but NICE explicitly recommends against routine chest X-rays for all elective surgical patients. A chest X-ray may still be appropriate when symptoms, known lung disease or another clinical indication makes it useful.
Similarly, breathing tests such as spirometry, arterial blood gas analysis or specialist respiratory review are generally considered when the person’s lung health or planned procedure warrants them. The anaesthesia team will also ask about asthma, smoking, recent respiratory infections and symptoms such as breathlessness.
Sleep apnoea is important to disclose, particularly when general anaesthesia or sedating medications are planned. Tell the team if you use a CPAP machine, have a previous sleep study or have been advised you may have obstructive sleep apnoea. Not every patient needs a new sleep study before surgery.
A recent chest infection, fever or other respiratory symptoms can change the clinical plan even when older test results were normal. Report any new illness before travelling and again during hospital assessment.
What about urine tests, pregnancy tests and infection screening?
A urine sample may be requested for a particular clinical reason, but routine urine dipsticks are not recommended for every surgical patient in NICE NG45. A urine culture may be appropriate if identifying a urinary infection would affect whether the operation can proceed.
For people who could be pregnant, the clinical team may ask about the possibility of pregnancy and discuss appropriate testing. NICE recommends a sensitive discussion and a pregnancy test with consent if there is doubt, alongside the hospital’s own pregnancy-checking protocol.
Some procedures or hospitals may also request infection-related screening based on clinical circumstances and local policy. The need for tests such as hepatitis screening or other infectious disease investigations is not identical across all operations and facilities; patients should be informed about why testing is proposed and how the results will be used.
Common preoperative tests at a glance
| Check or test | Why it may be done | Is it automatic for everyone? |
|---|---|---|
| Medical history and vital signs | Review general health, medicines and current condition | Core part of clinical assessment |
| Full blood count | Look for anaemia and blood-count abnormalities | No; more relevant for major/complex surgery |
| Kidney function and electrolytes | Assess kidney health and salt balance | No; based on procedure and medical risk |
| Blood glucose or HbA1c | Assess glucose levels or diabetes control | No; HbA1c particularly for known diabetes |
| ECG / EKG | Record the heart’s electrical activity | No; depends on health and surgery |
| Clotting tests | Investigate selected bleeding or anticoagulation concerns | No; clinically indicated |
| Ultrasound or other imaging | Examine a specific organ or surgical issue | No; procedure-specific |
| Chest X-ray / breathing tests | Investigate relevant chest or respiratory concerns | No; not routine for all patients |
| Pregnancy testing | Clarify pregnancy status where relevant | Depends on individual circumstances and local protocol |
The table summarises common possibilities, not the mandatory checklist of any named hospital in Turkey. The final requirements should come from your treating clinical team.
Do the tests differ for plastic surgery, bariatric surgery and other treatments?
Yes. The purpose and magnitude of the procedure influence which examinations and investigations can change surgical decisions.
Plastic surgery: breast surgery, tummy tuck and liposuction
Before a major plastic surgery procedure, the surgeon and anaesthetist may review blood counts, relevant metabolic tests and your risk factors for complications. The assessment also covers smoking or nicotine use, medications, bleeding history, previous operations and the likelihood of blood clots.
Not every patient needs breast imaging, an abdominal ultrasound or a cardiology appointment. Tests should be selected because they are clinically relevant, rather than because a treatment is advertised as a “package”.
Bariatric surgery: gastric sleeve and gastric bypass
Weight-loss surgery can require a more detailed assessment of diabetes, heart and lung health, sleep apnoea, nutritional status and conditions related to obesity. The programme may include additional blood tests, nutritional review or selected gastrointestinal investigations according to symptoms, the operation and local protocols.
Patients with diabetes or significant medication requirements may need a tailored perioperative plan. A gastric sleeve patient should not assume that a blood test performed months before travel is sufficient for current surgical clearance.
The American Society for Metabolic and Bariatric Surgery emphasises lifelong nutritional follow-up after bariatric operations, but the tests needed after surgery are not the same as those used to assess readiness beforehand. Our gastric sleeve aftercare blood-test guide focuses on that later phase.
Gynaecological procedures and other surgery
Pregnancy considerations, anaesthetic planning and the exact procedure can affect preoperative testing before gynaecological surgery. Pelvic ultrasound or other assessments may be needed for a particular symptom or diagnosis, but should not be represented as routine for every genital aesthetic procedure.
Dental work performed under local anaesthesia may follow a different pathway from surgery under general anaesthesia. Dental radiographs or three-dimensional scans, when indicated, assess the teeth and jaw rather than replacing a general surgical anaesthetic assessment.
When are pre-op tests done: before travel or after arriving in Turkey?
There is no standard schedule shared by every provider. Some patients can submit recent medical records, test results or specialist letters before travelling, while some investigations and the final anaesthesia assessment take place at the treating hospital.
For international patients, sending important information early can identify issues that might otherwise become apparent only after flights and accommodation have been booked. The Royal College of Anaesthetists recommends early preoperative assessment so that health conditions can be addressed before the planned procedure.
If the hospital accepts some previous test results, it may not be necessary to repeat them. Conversely, a test may need repeating if the original result is too old, the patient’s condition has changed or local clinical requirements call for an updated result.
Ask whether your assessment is planned for the day of arrival, the day before surgery or earlier; also ask what happens if additional review is needed. Do not assume that every possible examination can be completed and interpreted immediately after a late-night flight.
What does the anaesthetist check before surgery?
The anaesthetist reviews medical conditions, airway anatomy, previous anaesthetic reactions, medicines, allergies, fasting status and the nature of the operation. They may examine your mouth, teeth, jaw and neck movement and ask about snoring, reflux, sleep apnoea and exercise tolerance.
The Royal College of Anaesthetists’ patient guidance advises preparing medication information and ensuring that existing health conditions are adequately managed before surgery. The anaesthetist’s decision is informed by clinical assessment and any appropriate tests, not simply a single “pass” result.
Patients should disclose all prescription medicines, over-the-counter products and supplements, including weight-loss medicines such as semaglutide or tirzepatide if relevant. These can affect planning, but there is no safe universal instruction to stop them for a fixed number of days without individual medical advice.
If you use blood thinners, insulin, inhalers or CPAP, ask for a personalised plan. Do not independently stop or change prescribed medication because of instructions given to another patient.
What if a blood test or ECG result is abnormal?
An unexpected result does not necessarily mean surgery is permanently cancelled. The clinical team may repeat a test, investigate the cause, adjust treatment, request a specialist review, change the operation or recommend postponement until a medical issue has been addressed.
For example, unexplained anaemia, uncontrolled diabetes, an important heart rhythm abnormality or signs of infection may lead to further assessment. The decision depends on severity, the nature of the operation and the risks of proceeding.
The Royal College of Anaesthetists notes that elective surgery may need to be delayed if relevant medical conditions are not sufficiently controlled. This is a safety decision, not an administrative failure.
We have separate CK Health Turkey guides on preoperative test results that may prevent surgery and why an operation may be postponed after arrival. Those articles address the consequences of unexpected findings in more detail.
What should you bring to your preoperative assessment?
A little preparation can make the appointment more useful and may help avoid unnecessary delays. Ask the provider beforehand which documents they need, and bring the following when relevant:
- A list of prescription medication, supplements and any medications you have recently started or stopped.
- Details of allergies and previous reactions to medicines, latex or anaesthesia.
- Copies of recent blood tests, ECGs, imaging and specialist letters, including dates.
- Discharge summaries from previous surgery, especially if anaesthesia was difficult or complications occurred.
- Information about diabetes, sleep apnoea, a bleeding disorder, heart or lung disease and any necessary medical equipment.
- Details of new symptoms such as fever, cough, chest pain, breathlessness or an infection.
- Questions about when to stop eating and drinking and how to take medicines on the day of surgery.
Always report changes even if you previously completed an online medical questionnaire. A new symptom, infection or medication may alter the team’s assessment.
Do you need to fast before blood tests or surgery?
These are two different questions. Certain laboratory tests may require specific preparation, while fasting before anaesthesia is intended to reduce the risk of regurgitation and aspiration. Not every blood test requires fasting, and the fasting requirements for laboratory testing should not be confused with those for general anaesthesia.
Follow the instructions provided directly by the treating team for your operation and anaesthetic. Fasting times can vary according to the procedure, medicines and individual risk, and some patients need special arrangements.
If you accidentally eat, drink or take a medicine contrary to instructions, tell the team promptly and accurately. Do not conceal it to avoid delaying the operation.
What do the final safety checks involve?
Before anaesthesia, hospital staff confirm that they have the right patient, planned procedure, relevant consent and appropriate preparations. The World Health Organization Surgical Safety Checklist includes identity and procedure confirmation, allergy checks, assessment of airway or aspiration concerns and ensuring the necessary anaesthesia safety measures are in place.
These are not extra laboratory tests. They are essential clinical safety checks that complement the earlier medical assessment.
Do not be concerned if several people ask your name or confirm which procedure you are having. Repeated verification is a standard safety principle. If anything differs from what you understood or agreed to, raise it before the operation.
Are preoperative tests included in the surgery package?
There is no universal answer. The terms of the individual quotation determine which routine preoperative services, specialist consultations and investigations are included. Additional tests requested after clinical review may be billed separately depending on the agreement.
Request written clarification of which tests are included, whether an extra cardiology review or imaging would cost more, and what happens if the procedure must be postponed for medical reasons. Financial arrangements should never pressure a patient to skip an indicated test.
The related CK Health Turkey article on unexpected surgery costs in Turkey addresses questions about additional investigations and the wider travel budget.
Questions to ask before you fly
A practical checklist can reduce uncertainty and clarify which arrangements apply to your particular operation:
- Which specific tests are planned? Request a list instead of assuming that every possible blood test, ECG or scan is included.
- Why are they needed? Ask which tests are routine for the planned procedure and which are based on your health history.
- Can you share previous results? Find out which records the hospital can review before travel and when tests must be repeated.
- When is the hospital assessment? Confirm the date, location and whether an overnight stay is required.
- Who makes the final decision? Ask when the surgeon and anaesthetist will determine readiness for the procedure.
- What happens if more tests are needed? Clarify specialist availability, potential changes to the surgical date and additional costs.
- What should you do with medicines and fasting? Obtain individual written instructions before the trip.
The answers should be consistent with your written treatment plan. If you have a complex medical history, a pre-travel review may be particularly helpful.
CK Health Turkey: preparing for a hospital assessment
CK Health Turkey in Antalya supports international patients exploring surgery and other medical treatment options in Turkey. The preoperative process should begin with sharing your relevant health information so that the treating clinical team can identify which examinations, documents and tests are needed for the proposed procedure.
A CK Health Turkey coordinator can help you understand the consultation and treatment journey and how to communicate information to the clinical team. The surgeon and anaesthetist at the treating medical institution remain responsible for determining which investigations are required and whether it is appropriate to proceed.
To discuss your proposed treatment and ask which preoperative checks may apply to you, contact CK Health Turkey for a personalised assessment.
Ultimately, the answer to what tests are done before surgery in Turkey is not a fixed list of blood tests, ECGs and ultrasounds. It is a patient-specific medical assessment that combines relevant investigations with a review of your health, medicines, procedure and anaesthetic risks. Getting that information before travel is one of the most useful ways to reduce uncertainty and prepare for surgery safely.
