MVista Histoplasma Ag Quantitative EIA
Use
The MVista Histoplasma Ag Quantitative EIA is a diagnostic test for detecting Histoplasma capsulatum antigen in patient specimens. It aids in the diagnosis of histoplasmosis, a fungal infection primarily affecting the lungs but can disseminate to other organs. This quantification of antigen levels helps in diagnosing the presence and severity of the infection, allowing for appropriate medical intervention.
Special Instructions
The test requires careful specimen handling and labeling, submitting one of the specified specimen types with appropriate refrigeration for transport. The testing laboratory advises that some body fluids may not have established reference ranges in this assay, and results should be interpreted in conjunction with clinical findings.
Limitations
Cross-reactions can occur with other fungal infections such as blastomycosis, paracoccidioidomycosis, and penicilliosis. Improper specimen treatment with agents like sodium hydroxide can degrade the analyte, impacting results. The assay's performance in various body fluids may not be fully established, which may limit its diagnostic utility in those matrices.
