Before your visit

Preparation Guidelines

Follow these guidelines to ensure accurate results. When you book, we’ll remind you of any test-specific instructions.

Fasting

Fasting means no food or calorie-containing drinks for 8–12 hours before your test (water is allowed).
Overnight fasting is common: e.g. nothing after 10 PM if your test is at 8 AM.
Avoid chewing gum, sweets, or milk. Black coffee without sugar is usually not allowed during fasting—check with us.
If you are on regular medication, ask your doctor whether to take it before a fasting test.

Blood tests

Wear loose sleeves so the arm is easily accessible.
Stay hydrated (water only for fasting tests) unless otherwise instructed.
Avoid heavy exercise right before the draw.
Inform the phlebotomist if you have had fainting or discomfort during previous blood draws.

Urine samples

First-morning urine is preferred for many tests (more concentrated).
Clean catch: wipe the area before collecting to avoid contamination.
Collect mid-stream urine into the sterile container provided.
Avoid collecting during menstruation for routine urinalysis when possible; inform the lab if submitted.

Stool samples

Use the container and spoon provided; do not contaminate with toilet water or urine.
Some tests require avoiding red meat, certain vegetables, or medications for a few days—we will give you written instructions.
Deliver the sample to the lab as soon as possible (usually within the time frame we specify).

Medications

Some medicines affect results. Tell us and your doctor about all medications and supplements.
Do not stop prescribed medication unless your doctor advises. We can note your medications on the requisition for interpretation.

Imaging (X-ray, ultrasound)

For abdominal ultrasound, you may be asked to fast for 6–8 hours for better visibility.
For some X-rays, remove metal objects (jewelry, belts).
Pregnancy: inform the staff before any X-ray or nuclear medicine procedure.
