INTENDED USE

Advantage Typhi IgM & IgG Card is a rapid solid phase immuno-chromatographic test for the qualitative differential and simultaneous detection of salmonella typhi (S. typhi) IgM and IgG antibodies in human serum / plasma. This test is for in vitro diagnostic use only and is intended as an aid in the earlier diagnosis of typhoid infection and in the determination of recent and past infection.

Advantage Typhi IgM & IgG Card is a lateral flow immunochromatographic assay. The test uses anti-human IgM antibody (test line M) and anti-human IgG (test line G) immobilised on a nitrocellulose strip. The conjugate contains colloidal gold conjugated to S. typhi antigen. When a specimen followed by assay buffer is added to the sample well S. Typhi specific IgM &/or IgG antibodies if present, will bind to S. Typhi antigen gold conjugate making antigen antibodies complex. This complex migrates through nitrocellulose membrane by capillary action. When the complex meets the line of the corresponding immobilized antibody (anti-human IgM &/or anit-human IgG) the complex is trapped forming a purplish pink band which confirm a reactive test result. Absence of a coloured band in the test region indicates a non reactive test result. A red procedural control line should always develop in the test device window to indicate that the test has been performed properly.

PERFORMANCE CHARACTERISTICS

The kit has been evaluated with the known panel of fresh as well as frozen S. typhi IgM & IgG antibody positive and negative samples and results are compared with licensced commercially available test. The samples included cross-reacting samples; Rheumatoid factor, anti-nucleur antibodies etc. Following is the in-house evaluation:
