Understanding LH & Testosterone Total
What is LH & Testosterone Total?
LH & Testosterone test is used for evaluation of hypogonadism, in the prediction of ovulation, evaluation of Infertility and diagnosing Pituitary disorders. Lh & Testosterone test can also help to evaluate conditions like loss of libido, Gynecomastia and erectile dysfunction.

Contains 2 testsThe LH test detects the levels of luteinising hormone in the blood. This test is done to evaluate:

Luteinising Hormone
Testosterone Total
A Testosterone Total test measures the level of testosterone hormone in the blood. Testosterone is a sex hormone that is mainly found in men but is also present in women in small amounts. The appearance of male physical characteristics is also due to this hormone.
The production of testosterone hormone is regulated by luteinizing hormone (LH), which is produced by the pituitary gland. As the levels of testosterone rise, the production of LH decreases which in turn slows down the production of testosterone. Similarly, when the levels of testosterone fall, it leads to an increase in LH production, which in turn stimulates testosterone production.
Most of the testosterone circulating in the blood gets attached to two proteins: albumin and sex hormone-binding globulin (SHBG), and some of it remains unattached which is called free testosterone. Free testosterone and albumin-bound testosterone are also known as bioavailable testosterone as they are easily available for the body to use for proper functioning.
