This hormone blood test measures levels of the key hormones and androgens that play an important role in governing masculinity and fertility. Please contact us if you need a sensitive oestradiol assay performed.
Testosterone is an anabolic hormone responsible for bone and muscle strength, as well as mood, energy and sexual function.
Most testosterone is strongly bound to sex hormone binding globulin (SHBG). This test measures the proportion of unbound testosterone which is available to the body's tissues.
Sex Hormone Binding Globulin (SHBG) is a protein that binds tightly to testosterone and oestradiol. Changes in SHBG levels can affect the amount of hormone that is available to be used by the body's tissues.
The principle active form of oestrogen in the body which has roles in gynecomastia, water/fat retention and hormone balance.
Levels of follicle stimulating hormone in men rise with age, but can also indicate testicular damage and reduced sperm production. Low levels of FSH are detected when men are not producing sperm.
Luteinising hormone is responsible for stimulating testosterone production and sperm generation. Raised LH can signal that the testes are not producing enough testosterone and is relevant when evaluating hypogonadism.
Progesterone has two major effects in men - it promotes testosterone production, and also modulates the effects of excessive oestrogen.
A hormone which is produced in the pituitary gland and plays a role in reproductive health. Raised levels in men can cause reduced sex drive, lack of energy, erectile dysfunction and fertility problems.
Insulin resistance is a common feature of women with PCOS. High levels of insulin can lead to increased testosterone production, as well as metabolic issues such as weight gain, increased risk of diabetes and cardiovascular risk.
A hormone produced by the pancreas that helps to control blood glucose levels and plays a role in controlling the levels of carbohydrates and fats stored in the body.
Polycystic ovaries are often a feature of hypothyroidism (an underactive thyroid), and similarly thyroid disorders are more common in women with PCOS.
Communicates with the thyroid gland to produce T3 and T4 which regulate metabolic functions. High TSH thyroid test levels indicates an underactive thyroid, and low levels an overactive thyroid.
Measures the thyroxine that is freely circulating and able to regulate metabolism. High FT4 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
Measures the triiodothyronine that is freely circulating. High FT3 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
An excess of testosterone produced by the ovaries is typically the main source of elevated androgens seen with PCOS, however 20-30% of women with PCOS have an excess of androgens that originates from the adrenal glands. This adrenal androgen excess can be detected by measuring DHEA-S levels - a mildly elevated DHEA-S level is common in women with PCOS.
The cortisol test measures 'the stress hormone' cortisol which mobilises the body’s nutritional resources in stressful situations. Prolonged elevation of cortisol can cause fatigue, immune dysfunction, and impact sex hormones.
A long-acting adrenal hormone which regulates energy production, the immune system, brain chemistry, bone formation, muscle tone and libido. DHEA-S is converted by the body into testosterone and other sex hormones.
