The ALPHA Cryptococcal Antigen enzyme immunoassay (CrAg EIA) is a qualitative
or semi-quantitative (titration) test system for the detection of capsular polysaccharide antigens
of Cryptococcus species complex (Cryptococcus neoformans and Cryptococcus gattii) in serum
and cerebrospinal fluid (CSF). It is a direct immunoenzymatic sandwich microplate assay, and has
been considered the most sensitive and specific EIA for the detection of cryptococcal antigen.
The Histoplasma Antigen EIA is the first and only commercially available diagnostic kit for
Histoplasma antigen detection. This diagnostic kit is a cost-effective alternative for hospitals
and labs that no longer wish to send specimens off to service laboratories.
Manage Your ID & CF Workload Or Sendouts Effectively
The Coccidioides Antibody EIA is a very useful tool to aid in the diagnosis of coccidiodomycosis.
This assay is a sensitive, specific, and rapid test for the qualitative detection of serum antibodies
against TP and CF antigens from Coccidioides.
Less False Positivity | Decreased ID Testing | FTE Savings
- Contains two 96-microwell plates
- Greatly reduces the potential for error
- Two antigen preparations enhance both the sensitivity and specificity of the assay.
The Blastomyces Antibody EIA is used for the qualitative detection of serum antibodies
directed of serum antibodies directed against yeast-phase antigens from Blastomyces.
This assay is a sensitive, specific, and rapid test, which can help consolidate the workload
of immunodiffusion and complement fixation testing.
Latex Agglutination (LA)
The Cryptococcus Antigen Latex Agglutination Test System has proven to be a a valuable
aid in establishing diagnosis of cryptococcosis. This assay is a simple, sensitive test system
that can be used on serum and CSF, and can give qualitative and semi-quantitative results.
The Coccidioides Antibody Latex Agglutination Test System is a sensitive and rapid screening
test. This assay does have a false-positive rate, so the results of this test should be confirmed
by EIA, Complement Fixation and/or Immunodiffusion.
The Histoplasma Antibody Latex Agglutination Test System can aid in the diagnosis of
histoplasmosis; however, cross-reactions with other fungal organisms may occur. Results
should be interpreted with caution, particularly if the titer is low and only one specimen
has been examined. It is recommended to confirm the LA test result with ID and/or CF.
The Sporothrix Antibody Latex Agglutination Test System can aid in the diagnosis sporotichosis.
Sporothrix is generally endemic to the tropical and subtropical regions of the Americas.
