Application Field:

The Emergency Department, the Laboratory Department, the Internal Cardiology Department, 

the Department of Cardiac Surgery, the community medical institution, and on-site emergency 

treatment;Providing a fast bedside diagnosis for the patient.

 

Principle of the Procedure: 

One high specific and sensitive NT-proBNP monoclonal antibody and one NT-proBNP polyclonal 

antibody are used for the test strips. The monoclonal antibody is biotinylated, gold-labelled and 

coated on the polyester film, and the polyclonal antibody is fixed on the test lines. The antibodies 

on the test lines form sandwich complexes with any NT-proBNP in the blood sample. The sample 

passes through the detection zone, in which the sandwich complexes gather along a line, 

appearing as a purplish red streak (the test or signal line). Excess gold-labelled antibodies gather 

along the control line,signaling visually that the test is valid.The intensity of the test line increases 

in proportion to the NT-proBNP concentration.
