Key result
Rapidpia point-of-care BNP assay matches SHIONOSPOT Reader performance with ~93% diagnostic agreement.
Why the study?
Rapid measurement of BNP is important for diagnosing congestive heart failure, but analytical performance comparison of new small-footprint immunochromatography readers was needed.
Does the Rapidpia point-of-care BNP assay provide comparable analytical performance to the SHIONOSPOT Reader in clinical samples?

The Rapidpia point-of-care BNP assay demonstrates high precision and strong correlation with an established assay, supporting its clinical utility for rapid heart failure assessment.
Rapid measurement of B-type natriuretic peptide (BNP) plays a practical role in the diagnosis of congestive heart failure. Analytical evaluation of a new small-footprint immunochromatography reader of BNP (Rapidpia®) was performed and compared with the commercially available SHIONOSPOT® Reader as the index. The new BNP assay had a within-run coefficient of variation (CV) of 9.0% and a between-run CV of 2.1%. Correlations between whole blood and plasma samples and those with the index SHIONOSPOT® Reader were y = 0.93x + 0.88, R2 = 0.98 and y = 1.08x - 6.67, R2 = 0.93, respectively. Based on our findings, the two point-of care (POC) assays for BNP, Rapidpia® and SHIONOSPOT® Reader, showed comparable results.

Ishida et al. (2012) studied Congestive heart failure (n=57). Rapidpia BNP assay vs. SHIONOSPOT Reader was evaluated on Method correlation between Rapidpia and SHIONOSPOT Reader BNP values (correlation coefficient of 0.93). The Rapidpia point-of-care assay for B-type natriuretic peptide demonstrated comparable analytical performance to the SHIONOSPOT Reader, with a correlation coefficient of 0.93 and 93.0% diagnostic agreement at a 100 pg/mL cut-off.
