May simplify BNP sample handling in HF labs; leaves open assay-specific validation in larger cohorts.
BNP samples can be safely stored at room temperature for up to 24 hours before freezing, simplifying sample handling for heart failure screening.
Gobinet-Georges et al. (2000) studied Heart failure. Different handling conditions (sample collection, storage temperatures, freezing temperatures) was evaluated on Stability of brain natriuretic peptide. Brain natriuretic peptide is stable at room temperature for 24 hours or up to 30°C for 12 hours, and aprotinin prevents degradation in samples preserved >1 month at -20°C.
