This check has been designed to investigate the possible causes of thinning hair and hair loss.
This test includes (expand individual tests for details):
C Reactive Protein (High Sensitivity)
C-Reactive Protein (CRP) is an inflammation marker used to assess whether there is inflammation in the body. Inflammation is your body protecting your tissues if you have been injured or have an infection. It is also used as a screen for auto-immune diseases.
This test will measure your Ferritin levels. Ferritin stores iron in the body. Ferritin is tested to identify the storage capacity of iron in the body.
Thyroxine (T4) is one of two major hormones produced by the thyroid gland (the other is called triiodothyronine (T3)). This test can tell whether the thyroid is performing properly. Thyroid hormones help regulate your metabolism (how the body functions).
Testosterone is a male sex hormone produced in the testicles of men. It is produced in much smaller amounts, in the ovaries of women. It is responsible for bone and muscle strength, as well as mood, energy and sexual function.
Sex Hormone Binding Globulin
Sex hormones, like testosterone and oestrogen are bound to sex hormone binding globulin (SHBG.) When they are bound they are unavailable to your cells. High SHBG levels means there is less unbound hormones available to the cells. Low SHBG levels means you may have an excess of available hormones.
Free androgen index (FAI) is a calculation used to determine the amount of male hormones (androgens) which are unbound in the bloodstream. Low levels of FAI in men indicate reduced levels of testosterone available to the cells which can lead to symptoms such as: loss of libido, difficulty gaining muscle mass, and erectile disfunction. In women high levels of FAI could signify polycystic ovary syndrome.
Thyroid Stimulating Hormone (TSH) is produced in the pituitary gland. It tells the thyroid gland to produce thyroid hormones (T3 & T4.) High levels of TSH indicate an underactive thyroid while low levels indicate an overactive thyroid.
