Reference Interval	For the diagnosis of chronic heart failure in non-acute onset, the recommended cut-off is 125 ng/L.

For the diagnosis of chronic heart failure in acute onset dyspnoea, the following cut-offs provide optimal sensitivity and specificity (ICON Study): All ages NTBNP less than 300 ng/L: RULE OUT HF Less than 50 years old, NTBNP greater than 450 ng/L: RULE IN HF 50 – 75 years old, NTBNP greater than 900 ng/L: RULE IN HF More than 75 years old, NTBNP greater than 1800 ng/L: RULE IN HF Source: Roche Diagnostics
