Lab tests: fasting, timing and results

Accurate results start with good preparation. Some tests need fasting; others do not. Your request form will say which applies.

Fasting tests

Usually mean no food for 8–12 hours. Water is often allowed — confirm with the laboratory desk.

Timing

Morning visits help for glucose and cortisol-related requests. Arrive with your clinic card and request form.

Ask at reception:
- Do I need to fast?
- When will results be ready?
- Should I stop any medicine before the test?
