Follicle-stimulating hormone (FSH) is a hormone that plays a key role in egg production and ovulation in women, and the production of sperm in men.

Luteinizing hormone (LH) is a hormone that works together with FSH, and it is responsible for reproduction. In men, it helps in the production of testosterone, while in women it helps in regulating the menstrual cycle and ovulation.

Vitamin D is a fat-soluble vitamin that plays a crucial role in bone health, immune function, and overall health. A blood test for Vitamin D measures the amount of this vitamin in the blood. The test is typically done to evaluate the levels of Vitamin D in the body and to help diagnose and monitor conditions such as vitamin D deficiency, osteoporosis, and rickets.

Hemoglobin A1C (HbA1c) test measures the average blood sugar (glucose) levels over the past two to three months, and it is a common test used to monitor glucose control in people with diabetes. It is important to maintain good glucose control, as uncontrolled diabetes can lead to a range of serious health problems, such as health diseases, nerve, and kidney damage.

Total testosterone is a measure of the total amount of testosterone in the blood, including both bound and unbound testosterone. Testosterone is an important hormone that helps regulate many bodily functions such as building muscle, increasing body hair, and deepening the voice. It also plays a role in sexual function, mood, and bone health. Measuring total testosterone can help identify decreased bone density, risk of osteoporosis, causes of low sex drive, erectile dysfunction, and infertility.

Free testosterone is a type of testosterone that is not bound to sex hormone-binding globulin (SHBG) or albumin. As a type of testosterone, it is made in the testicles in men and in the ovaries and adrenal glands in women, and it is responsible for the development of secondary sexual characteristics such as increased muscle mass, body hair, as well as sexual function. The results of a free testosterone test can provide information about a person's testosterone status and can help to identify the cause of low sex drive, erectile dysfunction, acne, and body hair growth.

The Sex Hormone Binding Globulin (SHBG) is a protein that helps in the transport of hormones and controls the availability of sex hormones that your body can use. Testing SHBG you can get information about the level of sex hormones that are active and available for use.

Albumin is often used to evaluate overall health. Albumin is a type of protein that is produced by the liver and the most abundant albumin is found in the blood plasma. It helps transport nutrients, medications, and hormones throughout the body, but it also helps in tissue healing and cell growth.
