Niacin Level Blood Test - More Information

The vitamin B3 test, also known as a B3 blood test, niacin level test, niacin lab test and a nicotinic acid test, measures the vitamin B3 blood level.

Vitamin B3, commonly known as niacin, is an essential nutrient. Dietary niacin is found in meat as well as fortified foods. Niacin is used medically in the treatment of high cholesterol and seems to reduce cardiovascular risk in some people. Low niacin levels, also known as a niacin deficiency, can cause mouth problems, anemia and fatigue. Known as pellagra, people with low niacin levels are typically found in poor areas with malnutrition.

This vitamin B3 test checks both nicotinamide and nicotinic acid blood levels. To get a vitamin B3 test near you, simply order online and get your blood drawn at the Quest Diagnostics' lab that you selected. Once your vitamin B3 lab results are ready, they will be available for download.
