Guide

Which blood test do I need?

Not sure where to start? Here’s a simple guide to choosing the right blood test for common symptoms and goals. If you’re still unsure, call us and we’ll help you choose.

Feeling tired all the time

Start with a Full Blood Count for anaemia, a Thyroid Function test and Vitamin D. Together they cover the most common blood-related causes of tiredness.

A general health check

The Well Person, Well Man or Well Woman profiles cover heart, diabetes, kidney and liver health in one sample.

Heart health

A Cholesterol test, or the Cardiovascular Profile, which adds ApoB and lipoprotein(a) for the same price.

Diabetes risk

An HbA1c test shows your average blood sugar over the past two to three months, with no fasting needed.

Trying for a baby

The Fertility Package covers 14 hormones, an AMH test estimates your egg reserve, and a Day 21 Progesterone test confirms ovulation.

Menopause symptoms

The Perimenopausal Profile checks reproductive hormones and your thyroid together.

Low energy or sex drive in men

A morning Testosterone test, ideally with SHBG, plus a Well Man check.

Sexual health

HIV, syphilis, hepatitis B and hepatitis C blood tests, timed correctly after any possible exposure.
