A rapid test for the qualitative detection of IgG and IgM antibodies to Salmonella typhi (S. typhi) in human serum or plasma CE certified
The Typhoid Rapid Test Cassette is a rapid chromatographic immunoassay for the simultaneous detection and differentiation of IgG and IgM types of antibodies against Salmonella typhi (S. typhi) in human serum or plasma. It is intended to be used as a screening test as an aid in the diagnosis of infection with S. typhi. Any reactive specimen with the Typhoid rapid test cassette needs to be confirmed with alternative testing method.
Typhoid fever is caused by S. typhi, a Gram-negative bacterium. World-wide an estimated 17 million cases and 600,000 associated deaths occur annually1. Patients who are infected with HIV are at significantly increased risk of clinical infection with S.typhi2 . Evidence of h. pylori infection also presents an increase risk of acquiring typhoid fever. 1-5% of patients become chronic carrier harboring S. typhi in the gallbladder. The clinical diagnosis of typhoid fever depends on the isolation of S. typhi from blood, bone marrow or a specific anatomic lesion in the facilities that cannot afford to perform this complicated and time consuming procedure, Widal Test (also referred as WeilFelix Test) is used to facilitate the diagnosis. However, many limitations lead to difficulties in the interpretation of the Widal test.
In contrast, the Typhoid Rapid Test Cassette is a simple and rapid laboratory test. The test simultaneously detects and differentiates the IgG and the IgM antibodies to S.typhi specific antigen in serum or plasma thus aid in the determination of current or previous exposure the S.typhi.
How to use?
* NOTE: It should be add one more drop of (approx. 40ul) buffer to the sample well of the test cassette if the specimen runs too slowly.
INTERPRETATION OF RESULTS
(Please refer to the illustration above)
POSITIVE:* Two or three lines appear. One colored line should always appear in the control line region (C) and another one or two apparent colored line(s) should be in the test line region(s) (IgM and/or IgG).
IgM Positive: Along with line in Control region (C), a line appears in IgM region. It indicates a positive Test result for antibodies to S. typhi (Isotype IgM)
IgG Positive: Along with line in Control region (C), a line appears in IgG region. It indicates a positive Test result for antibodies to S. typhi (Isotype IgG)
*NOTE: The intensity of the color in the test line regions (IgM and IgG) may vary depending on the concentration of Typhoid antibodies present in the specimen. Therefore, any shade of color in the test line region (IgM and/or IgG) should be considered positive.
NEGATIVE: One colored line appears in the control line region (C). No line appears in the test line regions (IgM and IgG).
INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
