Description

English name: NT-proBNP test

【Forecast use】

It is used to detect the concentration of N-terminal brain natriuretic peptide (NT-proBNP) in human whole blood samples. Clinically, it is mainly used for auxiliary diagnosis of heart failure.

[Detection principle]

This product adopts immunofluorescence quantitative detection technology and immunochromatography. It is used to detect the content of N-terminal brain natriuretic peptide (NT-proBNP) in human whole blood samples. The blood sample and the sample buffer are mixed in a buffer bottle. The fluorescently labeled anti-N-terminal pro-brain natriuretic peptide (NT-proBNP) antibody in the buffer and the N-terminal pro-brain natriuretic peptide (NT-proBNP) antibody in the blood are mixed. -proBNP) The antigen binds to form an antigen-antibody complex. When the mixture sample is added to the sample hole of the test card, it diffuses forward along the nitrocellulose membrane under the action of chromatography, and the complex is fixed on the N-terminal brain natriuretic peptide precursor (NT- proBNP) antibody capture. The more N-terminal brain natriuretic peptide (NT-proBNP) in the blood sample, the more complexes will accumulate on the detection line. The signal intensity of the fluorescent antibody reflects the captured N-terminal brain natriuretic peptide The amount of peptide precursor (NT-proBNP) is processed by a dry immunofluorescence quantitative analyzer to detect the concentration of N-terminal brain natriuretic peptide (NT-proBNP) in blood samples. The analyzer's default N-terminal brain natriuretic peptide (NT-proBNP) detection result uses pg/mL as the unit.
