This test measures retinol level in the blood; retinol is the primary form of vitamin A in animals. Vitamin A is an essential nutrient required for healthy vision, skin growth and integrity, bone formation, immune function, and embryonic development.
Thiamin also known as vitamin B1 is one of the water-soluble B vitamins. Thiamin is added to some food products, naturally present in some foods, and offered as a dietary supplement. This vitamin plays a important role in energy metabolism and, therefore, in the growth, development, and function of cells
Vitamin B6, a water-soluble vitamin, acts as a coenzyme (pyridoxal-5-phosphate) in protein, carbohydrate, and lipid metabolism, as well as in heme synthesis.
The vitamin B12 level is a blood test that measures how much vitamin B12 is in your blood.
Folate and folic acid are types of a water-soluble B vitamin. Folate occurs naturally in food, and folic acid is the synthetic form of this vitamin.
Folate and folic acid are types of the water-soluble essential vitamin B9. While the two terms are often used interchangeably, folate is the naturally occurring vitamin found in dark leafy green vegetables, citrus fruits, and liver, as opposed to folic acid which is a synthetic form of B9 found in supplements and added to fortified foods such as cereal and loaves of bread.
Vitamin C is an essential dietary nutrient. It is a reducing agent (electron donor) that acts as an antioxidant and as a cofactor for various enzymes. Vitamin C has a role in the stimulation of neutrophil chemotaxis; lipid and protein metabolism; and the synthesis of collagen, carnitine, neurotransmitters, prostaglandins, and nitric oxide. It also facilitates the absorption of iron. A deficiency of vitamin C can lead to the development of scurvy.
Plasma or serum levels of vitamin C are an adequate measurement of clinical status, although leukocyte levels are superior but more difficult to obtain.
Vitamin D is a nutrient that is essential for healthy bones and teeth. There are two forms of vitamin D that are important for nutrition: vitamin D2 and vitamin D3. Vitamin D2 mainly comes from fortified foods like breakfast cereals, milk, and other dairy items. Vitamin D3 is made by your own body when you are exposed to sunlight. It is also found in some foods, including eggs and fatty fish, such as salmon, tuna, and mackerel.
In your bloodstream, vitamin D2 and vitamin D3 are changed into a form of vitamin D called 25 hydroxyvitamin D, also known as 25(OH)D. A vitamin D blood test measures the level of 25(OH)D in your blood. Abnormal levels of vitamin D can indicate bone disorders, nutrition problems, organ damage, or other medical conditions.
Other names: 25-hydroxyvitamin D, 25(OH)D
A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is important for many body processes. It helps your nerves and muscles work well, prevents blood clots, and boosts the immune system. Vitamin E is a type of antioxidant, a substance that protects cells from damage.
Most people get the right amount of vitamin E from their diet. Vitamin E is found naturally in many foods, including green, leafy vegetables, nuts, seeds, and vegetable oils. If you have too little or too much vitamin E in your body, it can cause serious health problems.
Other names: tocopherol test, alpha-tocopherol test, vitamin E, serum
Vitamin K is a nutrient that the body requires in small, regular amounts. It is essential for the formation of several substances called coagulation factors as well as protein C and protein S that work together to clot the blood when injuries to blood vessels occur and to prevent excessive clotting.
