Which of the following best describes the exoantigen test? (AIIMS May 2012)
|A||An immunodiffusion test used to detect antibodies in serum using mycelial antigens.|
|B||A skin hypersensitivity test to detect prior exposure to a fungus using yeast phase antigens.|
|C||A latex agglutination test used to detect fungal antigen in specimens|
|D||An immunodiffusion test that uses antibodies to detect fungal ag’s in aqueous extracts of agar culture & obviates the need for yeast conversion to identify the mold.|
a. It is a gel immunodiffusion precipitin test to detect particular mycelial antigen using specific antibodies.
b. Test identifies mold forms of dimorphic fungi negating the need for conversion to the yeast form
