From 3 August 2020- NTPro-BNP Assay performed on Abbott Alinity
NTPro-BNP <125ng/L makes a diagnosis of congestive heart failure (CHF) very unlikely1 , while a NTPro-BNP >150ng/L is associated with increased 10 year mortality2.
Optimal sensitivity and specificity cut off for NTPro-BNP in CHF diagnosis in the ED was found with age-adjusted cut offs3,4
Age < 50 >450ng/L
Age 50 -75 >900ng/L
Age >75 >1800ng/L
