Testosterone
Testosterone is the main androgenic hormone that is made in the testicles. Testosterone levels are important in the regulation of male characteristics and male sexual development.
Sex Hormone Binding Globulin (SHGB)
SHGP (Sex Hormone Binding Globulin) is made in the liver. It binds to three sex hormones; DHT, testosterone and oestrogen. If SHGB levels are elevated it will directly impact the levels of free testosterone available in the body.
Albumin
Albumin is the most abundant serum protein in the blood. Albumin can bind to testosterone and can, therefore, directly impacts the free testosterone levels available. We, accordingly, test for albumin levels to accurately calculate free testosterone levels.
Free Testosterone Calc.
The majority of testosterone is bound to albumin and SHGB. With only 2 to 3% of testosterone naturally being available to cells. Our advanced Welzo free testosterone calculator measures the amounts of free unbound testosterone bioavailable in the body.
Symptoms of Low Free Testosterone Levels
Free testosterone is the amount of bioavailable testosterone levels which differs from total testosterone, which includes bound testosterone.
Symptoms of low free testosterone levels include:
- Poor muscular development
- Constant fatigue
- A potential susceptibility to obesity
- Depression
- Irritability
- Erectile dysfunction
- Reduced sex drive
Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert
Testosterone is a male sex hormone which naturally decreases with age. Abnormally low levels of this can affect sex drive, sleep, mood, muscle mass, and energy levels and cause increases in abdominal fat.
This blood test can give you a picture of the testosterone levels in your body. For males, these results can help you understand if you have abnormal levels, which may require further assessments and treatments to help with symptoms.
Why take a Free Testosterone Blood Test?
If you've been feeling symptoms of low energy, depression, irritability, erectile dysfunction and reduced sex drive it may be due to a lack of free testosterone within the body. This test measures the available testosterone within the body to determine if your body is producing healthy levels and if further treatment is needed.









Experts Opinion Free Testosterone Tests
"Testosterone levels can also vary in the day at different times. Hormones work in a close network with each other. Although some may be higher in women, abnormal levels of other hormones can also impact male health."
