There is nothing positive about false positives-
just more testing, more time, more worry.
Fortunately, BNP testing can assist in ruling out heart failure in symptomatic patients, with
fewer false positives than NT-proBNP.

Bayer’s BNP assay uses widely accepted, very
specific antibodies for a high clinical specificity that correctly excludes CHF >97% of the
time.

This means getting the patient out of the line and onto the correct treatment pathway
faster, with less additional diagnostic testing. Backed by Bayer’s family of Immunoassay
analyzers, you get fast turnaround time delivering hundreds of tests per hour to rule out
more patients-positively.
Fewer false positives. More confidence. That’s innovation in the real world,
only from Bayer HealthCare.
