About the product

AbChek Rapid Syphilis Antibody test (Device) is an immunoassay for the rapid and visual detection of antibodies to Treponema pallidum in human serum or plasma to aid in the diagnosis of Syphilis.

After placing the dipstick in a container with serum or plasma, the sample moves on to the conjugate pad containing colloidal gold particles conjugated with recombinant Treponema pallidum antigens (15KDa, 17KDa, 47KDa) and mouse IgG. If the sample contains detectable levels of the syphilis antibodies it reacts with the gold conjugated recombinant Treponema pallidum antigens (15KDa, 17KDa, 47KDa) to form a complex. This complex moves further and reacts with the respective recombinant Treponema pallidum antigens (15 KDa, 17KDa, 47KDa) test line on the nitrocellulose membrane area to form a colored band.  The unbound complex and the mouse IgG conjugated colloidal gold particles move further to the goat-anti mouse IgG-coated control area to form a colored band (Control line).  The appearance of the test line and control line in the respective areas indicates a positive result. The appearance of only the control line indicates a negative result.  The control line acts as procedural control. The Control line should always appear if the test is performed as per the procedure and reagents are working properly.
