About this profile
The Testosterone Profile is the complete check for anyone with symptoms that could be hormonal. It measures not just how much testosterone you have, but how much is available to your body and why levels may be off, all from one blood sample.
What's included and why
- Total testosterone, the main measure of your level.
- SHBG and albumin, the proteins that carry testosterone. They're needed to work out your free testosterone.
- Free testosterone (calculated), the share available for your body to use. It's often more telling than the total when SHBG is high or low.
- LH and FSH, the pituitary hormones that tell the testes or ovaries to make hormones. They help show whether a low level starts in the testes or ovaries, or in the pituitary gland.
- Oestradiol, which men make from testosterone and which affects mood, libido and body fat. In women it reflects ovarian function.
- TSH, a thyroid check, because an under- or overactive thyroid causes many of the same symptoms and also changes SHBG.
Who it's for
Men with tiredness, low sex drive, erection problems, low mood, loss of muscle or reduced morning erections, and women with irregular periods, acne or excess hair growth. It's also used to check hormone levels over time when you're under a doctor's care.
Book a morning appointment
Testosterone is highest early in the day, so please book between 9am and 11am at Slough, Victoria or Neasden, or ask for a morning nurse visit. You don't need to fast. If a result comes back low, it's usually repeated on another morning before any decisions are made.
Results and support
Most results are reported within hours of the sample reaching the laboratory and appear in your secure online account. To go through them with a doctor, book a GP consultation or contact our men's health clinic. Only need a single figure? Our testosterone and SHBG tests can also be booked on their own.
