Understanding Testosterone Total + Vitamin B12 + Vitamin D (25-OH) in Vijayawada
What is Testosterone Total + Vitamin B12 + Vitamin D (25-OH) in Vijayawada?
Testosterone Total + Vitamin B12 + Vitamin D (25-OH) test consists of three tests, namely, testosterone total, vitamin D & B12 in both men and women. Testosterone (a male sex hormone) is present in both men and women, but the levels are significantly higher in men, influencing various aspects such as sexual development, muscle and bone health, mood, and energy. Vitamin D is an essential nutrient that can be synthesized in the body upon healthy exposure to sunlight or absorbed from dietary sources. Vitamin B12 is necessary for various health aspects, such as maintaining a healthy nervous system, making red blood cells, and creating the genetic material of our cells. These tests are required for assessing general well-being and will help your doctor formulate an individualized treatment plan for you.

A Vitamin B12 test measures your vitamin B12 levels. Vitamin B12 is essential for various health aspects, such as maintaining a healthy nervous system, making red blood cells, and creating the genetic material of our cells. Low vitamin B12 levels are more likely to occur in older adults, children, vegans, vegetarians, people with diabetes, individuals who underwent gastric bypass surgery, women who are breastfeeding, and in conditions that impact absorption of this vitamin, like Crohn’s disease. Higher vitamin B12 levels are uncommon as excessive vitamin B12 is usually removed through the urine. However, some conditions, such as liver diseases and myeloproliferative disorders, can cause an increase in vitamin B12 levels, thereby affecting blood cell production.

Vitamin D (25-Hydroxy)
A Vitamin D (25-Hydroxy) test measures the levels of vitamin D in the body. It is an essential nutrient that can be synthesized in the body upon healthy exposure to sunlight or absorbed from dietary sources. It majorly exists in two forms: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D2 is present in plants, such as yeast or mushrooms, and is available as a supplement in fortified foods, and vitamin D3 is found in foods like cheese, green vegetables, mushrooms, egg yolks, and fatty fish.
Both forms of vitamin D (D2 and D3) need to undergo some chemical changes before being available for use in the body. These chemical changes take place in the liver or kidneys. The liver converts vitamin D to 25-hydroxyvitamin D (25-OH vitamin D). A Vitamin D (25-Hydroxy) test measures the level of this 25-OH vitamin D as it is the primary form of vitamin D that circulates in the blood.

A Testosterone Total test measures the level of testosterone hormone in the blood. Testosterone is a steroid hormone primarily produced in the testes in men, although it is also present in smaller quantities in the adrenal glands. In women, it is made in small amounts by the ovaries. It is predominantly associated with male physiology and significantly influences physiological functions in both men and women.
The pituitary gland produces luteinizing hormone (LH), which regulates testosterone production. As testosterone levels rise, LH production decreases, slowing down testosterone production. Conversely, when testosterone levels fall, LH production increases, stimulating 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, called free testosterone. Free testosterone and albumin-bound testosterone are also known as bioavailable testosterone, as they are readily available for the body to use for proper functioning.
