How to Prepare for Your Test

Follow these guidelines for accurate results

Sample Timing

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.

Fasting & Hydration

Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.

Medications & Supplements

Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.

Hormones & Menstrual Cycle

For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.

If you have any questions or special circumstances, our team is happy to advise before your appointment.
