A test for B-type natriuretic peptide (BNP) or N-terminal pro b-type natriuretic peptide (NT-proBNP) is primarily used to help detect, diagnose, and evaluate the severity of heart failure.
The biuret test is a chemical test used for detecting the presence of peptide bonds. In a positive test, a copper(II) ion is reduced to copper(I), which forms a complex with t â¦ he nitrogens and carbons of the peptide bonds in an alkaline solution.A violet color indicates the presence of proteins.he biuret test is a chemical test used for detecting the presence of peptide bonds. In the presence of peptides, a copper(II) ion forms a violet-colored complex in an alkalin â¦ e solution.
