Normal range < 100 (heart failure unlikely) pg/mL (< 100 ng/L SI). Specimen: Plasma (EDTA).

Also known as: brain natriuretic peptide.

Reference range

This result is reported qualitatively or as a one-sided threshold rather than a two-sided numeric band.

Combined adult band. LabVals does not publish separate men's, women's, or pediatric ranges for B-type Natriuretic Peptide (BNP); those can be narrower than the band shown.

What is the normal range for B-type Natriuretic Peptide (BNP)?

The standard teaching reference range for B-type Natriuretic Peptide (BNP) is < 100 (heart failure unlikely) pg/mL in conventional units, or < 100 ng/L in SI units. This value is measured in plasma (edta).

Source: Adult reference values compiled from Pagana & Pagana, Mosby's Diagnostic and Laboratory Test Reference, and Fischbach & Dunning, A Manual of Laboratory and Diagnostic Tests. Reference ranges vary by laboratory, method, age, sex, and population - always use the range printed on the actual result.

Nursing considerations

  • Helps distinguish cardiac from pulmonary causes of dyspnea.
  • Trend it to gauge response to heart-failure therapy.
