Technology: staysafe® 4-in-1 STI Rapid Test is a lateral flow chromatographic immunoassay based on the principle of the double antigen-sandwich technique. The membrane is coated with recombinant antigens on the test region of the cassette. Colloid gold is one of the most common markers in lateral flow assays. If antibodies were present in the blood, they would react with the colloid gold-conjugated antigen to form an antibody-antigen complex. This complex would flow through the cassette and bind to the antigen in the test region, forming a gold-conjugated Ag-Ab-Ag sandwich complex, producing a pink-rose band.



Negative: Only one band appears on region C of the cassette. This indicates that there is no detectable antibody in the whole blood*.

Positive: Bands appear on both region C and T/T1/T2#. This indicates that the specimen contains detectable amount of antibodies#.

Invalid: Absence of color in region C is an indication of procedure error and/or the test reagent deterioration. Repeat the test with a new cassette.


*HBsAg tests for HBV surface antigen.

#HSV has two test region T1/T2. Any band appears in T1 and/or T2 indicates positive.
