Prolactin is a hormone whose primary function is helping women produce milk after childbirth.
It’s important for both male and female reproductive health. A Prolactin test is just like a blood test. The sample is typically collected three to four hours after waking up in the morning. Some birth control pills, high blood pressure drugs, or antidepressants can affect the test results. Tell your doctor about any medications you’re taking before the test is done. Sleeping problems, high stress levels, and strenuous exercise before the test can also influence the results.
Testosterone is responsible for the development of the male external genitalia and secondary sexual characteristics. In females, its main role is as an estrogen precursor. In both genders, it also exerts anabolic effects and influences behavior. A testosterone level test is a simple blood draw that doesn’t require much preparation.
A thyroid-stimulating hormone (TSH) test measures the amount of TSH in blood. TSH is produced by the pituitary gland, which is responsible for regulating the amount of hormones released by the thyroid. A TSH test is often performed to determine the underlying cause of abnormal thyroid hormone levels. It’s also used to screen for an underactive or overactive thyroid gland. The level of TSH in the blood, can determine how well the thyroid is working.
