How do I prepare for this test?

Fasting for 8-12 hours before your test (water only) is recommended where glucose, cholesterol or triglyceride accuracy matters. Book your sample between 7:00am and 10:00am. Stay hydrated, and avoid strenuous exercise, heavy meals and supplements including iron, B12, multivitamins and biotin for 48 hours beforehand. Continue any prescribed medication unless your doctor has told you otherwise.

Do I need a doctor's referral?

No referral is needed. You can book directly, and your results are reviewed by a doctor before you receive them. This test is not a diagnosis on its own, so discuss anything unexpected with your GP or a clinician.

CA125 Blood Test

1 Biomarker | Venous Blood Test | UKAS-accredited laboratory

CA125, a protein that can be raised in a range of conditions affecting the ovaries and abdomen. Designed for people already under clinical care who have been advised to monitor this marker, rather than for general screening, this test gives you a clear laboratory result alongside the reference range so you can see exactly where you sit.

Results are typically available within 2 working days from when your sample reaches the laboratory (excluding weekends and bank holidays).

Doctor's comments are optional on individual markers. Add them for £15.00 at checkout, or your result is issued as a laboratory report showing your value alongside the reference range.

A laboratory result is not a diagnosis. If you have urgent or worrying symptoms, contact your GP or call 111. In an emergency call 999.
