Quick answer
The vitamin B3 test measures niacin, a water-soluble vitamin the body uses to convert food into energy. Niacin also supports the skin, the digestive tract, and the nervous system. The test is ordered when a deficiency is suspected because of poor nutrition, certain medical conditions, or long-term use of some medications. A blood sample is used, and results are interpreted with diet and symptoms.
What this test measures
Vitamin B3, also called niacin, is a building block for the coenzymes NAD and NADP, which take part in hundreds of reactions that release energy from food. Like other B vitamins, niacin helps cells process carbohydrates, fats, and proteins. It also plays a role in repairing DNA and in signaling within cells.
Testing may measure niacin or its metabolites in blood or urine. Some laboratories assess the ratio of niacin metabolites to creatinine to gauge status. The collection is a standard blood or urine sample, and the report compares the finding with a method-specific reference range.
Deficiency is uncommon in people with varied diets, since niacin is found in meat, fish, poultry, nuts, and fortified grains, and the body can make some from the amino acid tryptophan. When it does occur, it can affect the skin, digestion, and mental function. Testing helps a healthcare provider decide whether niacin status is relevant to symptoms.
