Pre-Surgery Blood Tests: Complete Guide to Tests Required Before Surgery

Pre-Surgery Blood Tests: Complete Guide to Tests Required Before Surgery

Before undergoing any surgical procedure, doctors may recommend a series of blood tests to assess your overall health and identify potential risks. Pre-surgery blood tests help doctors and surgeons understand whether your body is ready for the planned procedure and whether any medical conditions require attention before surgery.

The exact tests required can vary depending on your age, medical history, type of surgery, medications, and your doctor's recommendations.

Why Are Blood Tests Required Before Surgery?

Pre-operative blood tests provide important information about your health before anaesthesia and surgery. These tests can help doctors identify issues such as anaemia, infection, abnormal blood sugar levels, kidney problems, liver function concerns, or blood clotting abnormalities.

Getting the recommended tests done before surgery may help your medical team plan the procedure safely and take necessary precautions.

Common Blood Tests Before Surgery

Complete Blood Count (CBC)

A Complete Blood Count measures important components of your blood, including haemoglobin, red blood cells, white blood cells, and platelets.

Doctors may use this test to check for:

Anaemia

Signs of infection

Low platelet count

General blood health

Blood Sugar Test

Blood glucose testing may be recommended before surgery, especially for people with diabetes or those at risk of high blood sugar.

Uncontrolled blood sugar levels can affect recovery and wound healing. Your doctor may recommend fasting blood sugar, random blood sugar, HbA1c, or other tests depending on your health condition.

Kidney Function Tests (KFT)

Kidney function tests help assess how well your kidneys are working.

Common parameters may include:

Serum creatinine

Blood urea

Uric acid

Electrolytes

These results can be important when planning medications, anaesthesia, and post-operative care.

Liver Function Tests (LFT)

The liver plays an important role in processing medications and maintaining normal body functions.

Liver function testing may include parameters such as:

Bilirubin

SGPT/ALT

SGOT/AST

Alkaline phosphatase

Total protein

Albumin

Blood Grouping and Rh Typing

Blood group testing identifies your blood type and Rh factor.

This information can be important for surgeries where there is a possibility of blood loss and blood transfusion may be required.

Blood Clotting Tests

Doctors may recommend clotting tests before certain surgical procedures.

Common tests include:

Prothrombin Time (PT)

INR

Activated Partial Thromboplastin Time (aPTT)

These tests help assess how well your blood is clotting.

Other Tests Your Doctor May Recommend

Depending on the surgery and your medical history, additional investigations may be required.

These can include:

Urine routine examination

Thyroid function tests

HIV screening

Hepatitis B screening

Hepatitis C screening

ECG

Chest X-ray

Not every patient requires all these tests. Always follow your surgeon or physician's instructions regarding pre-operative investigations.

How to Prepare for Pre-Surgery Blood Tests

Preparation depends on the specific tests prescribed.

Some tests may require fasting for 8 to 12 hours. During fasting, you may usually be asked to avoid food and consume only water, unless your doctor provides different instructions.

Before your blood test:

Follow fasting instructions carefully

Inform the laboratory about medications you are taking

Carry your doctor's prescription if available

Stay hydrated unless instructed otherwise

Avoid alcohol before testing if advised by your doctor

When Should You Get Pre-Surgery Blood Tests Done?

The timing of pre-operative testing depends on the type of surgery and your doctor's recommendations.

Some tests may need to be completed a few days before surgery, while others may need to be performed closer to the procedure date.

It is always best to schedule your tests early enough so your doctor has sufficient time to review the reports.
