VITAMIN B3/NICOTINIC ACID

The vitamin B3 (nicotinic acid) test measures the level of nicotinic acid, an essential vitamin involved in energy metabolism and DNA repair, in the blood. This test is used to diagnose and monitor conditions affecting nicotinic acid levels, such as pellagra (a severe form of vitamin B3 deficiency) and certain metabolic disorders. Low nicotinic acid levels can indicate malnutrition or malabsorption. The nicotinic acid test provides valuable information for assessing nutritional status, diagnosing underlying conditions, and guiding treatment decisions to manage nicotinic acid levels effectively.
