Ultimate Performance Blood Test

For when you're running on empty. Your hormones, thyroid, iron and general health, checked in one clinic blood draw.

What it measures

More than 55 markers: a full blood count; TSH, free T4 and free T3; oestradiol, FSH, LH, SHBG, total and free testosterone, the free androgen index, prolactin, cortisol and DHEA-S; B12, folate, ferritin, iron and transferrin; HbA1c (your average blood sugar); a cholesterol profile; liver and kidney function; uric acid; magnesium; and CRP (a marker of inflammation).

How to give your sample

• Blood draw at a clinic near you: £225. Choose from more than 40 clinics across the UK and give me 3 times that suit you, right here when you pick this option. I'll book it and confirm by email.

Before you test

This one needs a blood draw at a clinic. A morning appointment is best, because cortisol and testosterone are highest early in the day. If you still have periods, I'll tell you which day of your cycle to book. On hormonal contraception or HRT? Tell me before you test, because it changes how some results read.

• Taking biotin (in many hair, skin and nail supplements)? Stop it 3 days before, and longer if it's a high dose, because it can upset thyroid and hormone results.
• If you take thyroid medicine, take your sample before that day's dose.
• If you take an iron supplement, stop it 5 to 7 days before.
• Been ill or had a vaccine in the last 2 weeks? Wait until the 2 weeks have passed, because it can push some results up.
• Avoid hard exercise for 48 hours before, because it raises some muscle and liver markers.

Your results and your written report

Your results come back to me, usually 1 to 3 working days after the lab receives your sample. You get the lab report, which is the numbers and their ranges, and a written report from me. In it I read your results together and explain what they mean for you, including any that sit inside the range but still matter. It's a written report, not a consultation. The price includes the lab fee and your report.

Who it's for

For you if you train hard and your recovery isn't what it was, you feel flat or tired most days, or you want your hormones and general health side by side.

A test result is one part of the picture. It does not diagnose a condition on its own. If you have symptoms that worry you, they need to be checked.
