One Step Test for NT-ProBNP/cTnI (Colloidal Gold) - One Step Test for NT-ProBNP/cTnI (Colloidal Gold)

One Step Test for NT-ProBNP/cTnI (Colloidal Gold)


Intended Use:
One Step Test for NT-proBNP/cTnI(Colloidal Gold) applies colloidal gold immunochromatography to detect N-terminal B-type natriuretic peptide precursor/cardiac Troponin I(NT-proBNP/cTnI)in serum and plasma samples semi -quantitatively or quantitatively. The combined detection of NT-proBNP/cTnI can help doctors diagnose, prognose and grade Heart Failure and Acute Coronary Syndrome more thoroughly.
Principle of the Procedure:
Two high specific and sensitive anti-human cardiac Troponin I monoclonal anti bodies, one high specific and sensitive NT-proBNP monoclonal antibody and one NT-proBNP polyclonal antibody are used for the test strips. Among other things, one cTnI monoclonal antibody and the NT-proBNP monoclonal antibody are biotinylated, gold-l abelled and coated on the polyester film, the other cTnI monoclonal antibody and the NT-proBNP polycolonal antibody are fixed on the test lines of the product.The antibodies form sandwich complexes with any NT-proBNP/cTnI 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 l ine). 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/cTnI concentration.

Warnings and Precautions:
1. Use for in vitro diagnostics.
2. Use by healthcare professionals.
3. The best testing temperature is 15~30℃, and the best humidity is 40~60%.
4. Do not use the stri p beyond the expiration date printed on the outside of the box.
5. The strip must be used within 1 hour once its foil pouch has been opened.
6. The transfer pipette shoul d be used for one specimen only. Discard it after used.
7. Patient specimens, used strip and transfer pipettes may be potentially infectious. Proper handling and disposal methods should be established by the laboratory direction in accordance with local regulations.
8. Proper laboratory safety techniques should be followed at all times when working with potentially infectious blood specimens.
