Testosterone blood test: If you’re wondering how testosterone is measured in a blood test, you’re not alone. The test measures testosterone levels in two different ways: in the blood and saliva. While blood samples are usually collected through venipuncture, saliva samples are often easier to collect. Both types of tests have different uses. Below we’ll outline how testosterone is measured in blood and saliva. To understand its role in blood tests, consider these three examples.
Testosterone is a male sex hormone
In both boys and girls, testosterone is a primary sex hormone. Testosterone is the male hormone responsible for muscle development, the deepening of the voice, and sperm production. In adults, it controls sex drive, contributes to libido, and regulates some bodily functions. Testosterone is also produced by the pituitary gland, a pea-sized gland located at the base of the brain. Men can take a blood test to check the level of this hormone and see if it is causing any underlying conditions.
When measured in a blood test, the levels of testosterone are crucial for healthy male sexual development and function. Normal levels of testosterone help boys develop male features during puberty, including a deeper voice and more muscle strength. During puberty, testosterone is essential to produce sperm. Testosterone levels decrease over time as men grow older, but sometimes they are very low. This condition is known as Testosterone Deficiency Syndrome, and it has many symptoms.
It is measured in picograms per millilitre (pg/mL)
The levels of this hormone in the body are often measured in a blood test. It is measured in picograms per millilitre (pg/mL). Blood tests will typically measure three hormones: parathyroid hormone (PTH) and cortisol. While some symptoms may not be immediately apparent, they may indicate a more serious problem. If your doctor suspects anaemia, a vitamin B12 test may be ordered.
It is used to evaluate hirsutism and masculinization in women
A comprehensive history should be obtained to determine the underlying causes and the risk of developing hirsutism. The patient should note any exposure to irritants and drugs, changes in extremity size and facial contour, and family history of similar disorders. A physical examination is also essential to determine the extent and type of excessive hair growth, associated abnormalities, and whether or not hirsutism is present.
A woman may experience hirsutism, which is the excessive growth of male-pattern hair. About five to ten per cent of women of reproductive age exhibit this problem. It may be a symptom of a more serious condition, such as polycystic ovary syndrome, insulin resistance, or a genetic condition. In some cases, excessive hair growth may be the only sign of a hormonal imbalance.
It is used to diagnose tumours of the ovary or adrenal gland
A biopsy is a method of choosing a suitable sample of tissue for further examination under the microscope. This is done with a needle made of a thin, hollow material called fine-needle aspiration. A radiologist guides the needle using specialized imaging procedures. The sample collected is then analyzed by a pathologist. If the biopsy is negative, the physician may recommend another procedure, such as surgery, if necessary.
A CT scan, or CAT scan, is another method of testing the adrenal gland. This test is extremely accurate at diagnosing tumours of the adrenal glands, and it is used for any type of adrenal tumour. It is quick and painless and can take as little as 30 minutes to complete. CT scan pictures are very helpful in identifying tumours throughout the body and provide accurate measurements that help the doctor plan the appropriate therapy.
