How the B3 Relates to Other Tests
Some markers overlap between the B3 and related panels, so results are best read together. The B3 is not a replacement for other tests; it complements them by focusing on its own markers. Keeping all your test reports together makes it easier to see how the B3 fits over time. The B3 looks at a defined set of markers and is often reviewed with other tests that cover related areas.
What the B3 Can and Cannot Tell You
What the B3 can tell you depends on the markers included and the quality of the sample. This blood test determines Vitamin B3 (niacin) deficiencies by measuring niacin levels. The B3 cannot capture factors that are not part of the panel, such as symptoms or medical history. A normal-looking B3 result does not rule out every possibility, just as an abnormal one is not a diagnosis.
High and Low B3 Results in Carson
High and low results from the B3 are best reviewed with a healthcare provider rather than interpreted alone. This blood test determines Vitamin B3 (niacin) deficiencies by measuring niacin levels. A single high or low value from the B3 may reflect normal variation, so repeat testing is sometimes used. The meaning of a high or low B3 result depends on your history and on the other markers in the panel.
