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.

The vitamin B9 test is also known as the folic acid test, and it measures the amount of folic acid in your blood. It represents a B-complex vitamin that plays a crucial role in the production of DNA and RNA and helps in the formation of red blood cells. Further, intake of folic acid is especially important during pregnancy, as well as if the person has anemia or liver disease.

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.

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.

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.

Active B12 is an essential biomarker revealing your body's functional vitamin B12 status. It comprises 6-30% of total B12 reserves. Active B12 testing provides a precise assessment of your body's real-time B12 levels, identifying deficiencies earlier than total B12 testing alone. Adequate active B12 is critical for energy production, red blood cell formation, nerve function, and brain health. Low active B12 serves as a reliable deficiency marker, indicating risks of anaemia and neurological issues over time if not addressed. Regular active B12 testing allows early detection of potential deficiencies, enabling timely steps to improve status before long-term health problems develop.
