What this test is
This test measures the amount of vitamin B3, also called niacin, in a blood sample. Niacin is a water-soluble vitamin that helps convert carbohydrates into glucose and supports many bodily functions. The test is used to evaluate whether your niacin level is low, which can lead to deficiency symptoms.
What it measures
- Vitamin B3 (Niacin) — Reflects the amount of niacin circulating in the blood
- Niacin metabolites — May be measured in urine to assess niacin status over time
- Related B vitamin levels — Sometimes checked together to evaluate overall B vitamin status
What the test involves
The test usually requires a standard blood draw from a vein in your arm. In some cases, a urine sample may be collected instead or in addition, depending on the lab's protocol.
