Scrub Typhus IgM Microlisa test is an enzyme immunoassay based on“Indirect ELISA”. Recombinant protein representing immunodominant epitopes of Scrub Typhusare coated onto microtiter wells. Specimens and controls are added to the microtiterwells and incubated. IgM antibodies to Scrub Typhus if present in the specimen, will bind tothe specific Scrub Typhus antigen absorbed onto the surface of the wells. The plate is thenwashed to remove unbound material. Horseradish peroxidase (HRP) conjugated Anti-Human IgMis added to each well.

This conjugate will bind Scrub Typhus antigen-antibody complexpresent. Finally substrate solution containing chromogen and hydrogen peroxide is added to thewells and incubated. A blue color will develop in proportion to the amount of Scrub Typhus IgMantibodies present in the specimen. The color reaction is stopped by a stop solution. Theenzyme substrate reactionis read by EIA reader for absorbance at a wavelength of 450 nm. If thesample does not contain Scrub Typhus IgM antibodies then enzyme conjugate will not bind and thesolution in the wells will be either colorless or only a faint background color develops.
