The Testosterone Plus Profile provides a more complete assessment of your testosterone status by measuring both total testosterone and calculated free testosterone—the portion of testosterone that is biologically active and available for your body to use.
Alongside testosterone, the profile measures Sex Hormone Binding Globulin (SHBG) and Albumin, allowing for a more accurate calculation of free testosterone. This offers greater insight into hormonal health than measuring total testosterone alone.
Suitable for both men and women, this profile can help investigate symptoms related to hormone imbalance, monitor testosterone replacement therapy (TRT), or simply provide a clearer understanding of your hormonal wellbeing.
The test can be completed using either a finger-prick home sample or a phlebotomy blood sample.

Hormonal balance plays an important role in energy levels, muscle development, sexual health, fertility, bone strength, mood, and overall wellbeing. While total testosterone is useful, free testosterone often provides a more accurate picture of how much hormone is actually available for your body’s tissues.
By combining testosterone, SHBG, and albumin measurements, this profile calculates your free testosterone level, helping identify hormone imbalances that may not be obvious from a total testosterone test alone.
For the most accurate testosterone measurement, blood samples should ideally be collected between 7:00am and 10:00am, when testosterone levels are naturally at their highest.
Albumin is an important blood protein produced by the liver. In addition to supporting normal fluid balance and transporting nutrients and hormones throughout the body, albumin is used alongside SHBG and total testosterone to calculate your free testosterone level more accurately.
Albumin
Albumin is the most abundant protein in the bloodstream and plays a key role in carrying hormones, vitamins, medications, and other essential substances around the body. It also helps maintain fluid balance between blood vessels and surrounding tissues.
Within this profile, albumin contributes to the calculation of free testosterone, providing a more accurate assessment of the hormone that is available for use by the body's cells. Abnormal albumin levels may also indicate liver disease, kidney disease, inflammation, or poor nutritional status.
Hormones act as chemical messengers that regulate numerous body functions, including metabolism, muscle growth, fertility, sexual health, mood, and energy production. This profile evaluates the key markers involved in testosterone production and availability.
Free Testosterone (Calculated)
Free testosterone represents the portion of testosterone that is not attached to blood proteins and is immediately available for use by the body's tissues. Because only free testosterone is biologically active, it often provides a better reflection of hormonal function than total testosterone alone.
A calculated free testosterone result can help investigate symptoms such as low libido, fatigue, reduced muscle strength, fertility problems, or hormonal disorders in both men and women.
Sex Hormone Binding Globulin (SHBG)
SHBG is a protein produced mainly by the liver that binds to testosterone and other sex hormones in the bloodstream. The amount of SHBG present influences how much testosterone remains freely available to the body's tissues.
Measuring SHBG helps provide a more complete assessment of hormone balance and improves the accuracy of calculated free testosterone. Abnormal SHBG levels may also be associated with liver disease, thyroid disorders, ageing, obesity, PCOS, or other endocrine conditions.
Testosterone
Testosterone is a vital hormone in both men and women, although it is naturally present at much higher levels in men. It supports muscle mass, bone density, fertility, sexual function, mood, energy levels, and overall physical performance.
Low testosterone levels may contribute to fatigue, reduced libido, erectile dysfunction, infertility, loss of muscle mass, and low mood. Elevated testosterone can also indicate underlying hormonal conditions or the effects of certain medications and supplements.
Regular monitoring is particularly important for individuals receiving testosterone replacement therapy or those investigating symptoms related to hormonal imbalance.
Please note: For the most reliable testosterone result, it is recommended that your blood sample is collected between 7:00am and 10:00am.
