Assay and reagents for quantifying hBNP

摘要

The invention relates to an in vitro method of diagnosing congestive heart disease by quantifying hBNP in a sample. The method comprises: contacting a sample of the biological fluid with a first antibody, wherein the first antibody is monospecifically reactive to an hBNP fragment; forming a complex comprising hBNP in the biological fluid, the first antibody and a second antibody, wherein the second antibody is immunoreactive with hBNP or the first antibody, and wherein the second antibody comprises a label; and determining the amount of hBNP in the sample by quantifying the label in the complex.
