What it is

BNP and NT-proBNP are natriuretic peptide blood tests; the heart releases BNP when it works harder than normal to pump blood.^[1]

Why it matters

These tests are mainly used to help diagnose or rule out heart failure in people who have symptoms.^[1]

What it affects

BNP context is interpreted with exam, imaging, kidney function, age, symptoms, and clinical course.^[1,2]

Interpretation traps

BioConst does not classify heart failure or urgency from a BNP result.^[1]
