Overview
EPIC Code:
- LAB400
Soft Test Code:
- UHIS2
Send Out Test Code:
- 310
Alternate Names
- Histoplasma Quantitative EIA Test
Clinical Significance
The MVista® histoplasma quantitative antigen test aids the diagnosis of histoplasmosis. Monitoring the histoplasmosis helps determine when treatment can be stopped and to diagnose relapse.
The result is not intended to be used as the sole means for the clinical diagnosis or patient management decisions.
- Cross-reactions are seen with blastomycosis, paracoccidioidomycosis, penicilliosis, less frequently in coccidioidomycosis, rarely in aspergillosis and possibly sporotrichosis.
- Sputolysin, sodium hydroxide and potassium hydroxide treatment degrade the analyte detected in the assay.

Clinical Interpretation
Reference Range:
Non Detected
Test Comments:
Positive: 0.20-20.00 ng/mL
Positive Above the Limit of Quantification: Results greater than 20.00 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.
Methodology:
- Quantitative Sandwich Enzyme Immunoassay (EIA)
- Serum and CSF are pre-treated to improve sensativity
