MessageDietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.

Clinical Significance
NT-proBNP assay aids in the diagnosis of individuals suspected of congestive heart failure; is indicated for risk stratification of patients with acute coronary syndrome and congestive heart failure. Also aids in the assessment of increased risk of cardiovascular events and mortality for patients at risk of heart failure who have stable coronary artery disease.
Performing Laboratory
Quest Diagnostics
