A hormonal assay test is performed to give an indication of metabolic processes and conditions, or ‘hormone imbalance’. Many hormones can be measured (assayed) in the blood, including male and female sex hormones (oestrogen, progesterone, testosterone) and hormones secreted by other glands such as the parathyroid and adrenal glands.
Hormonal assays are a blood test and require a few millilitres of blood from a vein.
Specific hormones or sets of related hormones may be tested in a variety of clinical situations. Commonly, hormonal tests may be related to issues of fertility, menstrual irregularities, or menopause.
Your doctor may request specific hormonal tests if there is a suspicion of an endocrine problem, relating to the function of many glands in the body, including the pituitary, thyroid, parathyroid, adrenals, ovaries and testes.
