Free Testosterone Blood Test

Free Testosterone Blood Test

1 Biomarker | Venous or Capillary Blood Test | UKAS-accredited laboratory

The unbound, biologically active fraction of testosterone. Designed for people whose total testosterone reading needs context, particularly where SHBG is high or low, 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.

Frequently asked questions

What does the Free Testosterone Blood Test measure?

This test measures Free testosterone, the small unbound fraction that is available to your tissues. Total testosterone can look normal while free testosterone is low, so this gives a clearer picture.

Who is this test for?

Men with low libido, fatigue, mood changes or reduced muscle mass, and anyone monitoring testosterone replacement therapy.

How do I prepare for this test?
  • Fasting required 8-12 hours before the test (water only), recommended for glucose and cholesterol/triglyceride accuracy
  • Sample timing: between 7:00am and 10:00am
  • Stay hydrated; avoid strenuous exercise, heavy meals, and supplements (iron, B12, multivitamins, biotin) for 48 hours prior
  • Continue prescribed medications unless otherwise directed
How is the sample collected?

You can choose either a venous draw or a finger prick sample for this test. Venous draws are available at our Livingston clinic, at a partner clinic, or at home with a visiting nurse. Finger prick collection is done yourself using the kit we send out.

When will I get my results?

Results are typically available within approximately 2 working days of your sample reaching the laboratory. Every result is reviewed by a doctor before release and delivered securely to your online account. All testing is carried out in a UKAS-accredited laboratory.
