Blood tests are among the most common diagnostic tools in medicine. A small sample of your blood, drawn from a vein in your arm, can provide your doctor with a wealth of information about your health — from organ function to infection and chronic disease risk.
Common Types of Blood Tests
Your doctor will order specific tests based on your symptoms and medical history. The most frequently requested blood panels in Malaysian clinics include:
| Test Panel | What It Checks | Fasting Required? |
|---|---|---|
| Full Blood Count (FBC) | Red cells, white cells, haemoglobin, platelets | No |
| Lipid Profile | Cholesterol (LDL, HDL), triglycerides | Yes — 9–12 hrs |
| Fasting Glucose | Blood sugar level | Yes — 8 hrs |
| HbA1c | 3-month blood sugar average | No |
| Liver Function Tests (LFT) | Liver enzymes, bilirubin, albumin | No |
| Renal Function Tests (RFT) | Creatinine, urea, eGFR | No |
| Thyroid Function (TSH/FT4) | Thyroid hormone levels | No |
| Uric Acid | Gout risk | No |
How to Prepare
Preparation depends on the specific test. As a general rule:
- Fasting tests (lipid profile, fasting glucose): Nothing to eat or drink except water for 8–12 hours beforehand. Schedule your appointment in the morning to make fasting easier.
- Non-fasting tests: You can eat and drink normally. Take your regular medications unless your doctor says otherwise.
- All tests: Inform the phlebotomist of all medications and supplements you are taking, as some can affect results.
Tip: Drink plenty of water before your blood test — it makes veins easier to find and reduces the chance of a difficult draw. Avoid alcohol for 24 hours before any test.
What Happens During the Blood Draw
A trained phlebotomist will clean the inside of your elbow with an antiseptic swab, apply a tourniquet to make your vein more visible, then insert a small needle to draw the required amount of blood into collection tubes. The procedure typically takes less than five minutes. You may feel a brief pinch when the needle is inserted.
After the draw, a small cotton ball or gauze is pressed over the site. You should keep gentle pressure on it for a few minutes. Bruising at the site is common and resolves within a few days.
When Will You Get Results?
Most routine blood test results are available within 24–48 hours. Your doctor will contact you or discuss results at your follow-up appointment. Critical or significantly abnormal values are usually communicated more urgently.
Where to Get a Blood Test in Malaysia
Blood tests can be arranged through your GP, specialist or at a hospital outpatient laboratory. You can also arrange home collection through a mobile phlebotomy service — see our home collection guide for details. A doctor's referral is required for most diagnostic blood tests.
