Histoplasma Antigen EIA

310

The MVista® Histoplasma Quantitative EIA test aids in the diagnosis of histoplasmosis. Monitoring the Histoplasma antigen helps to determine when treatment can be stopped and to diagnose relapse.

• Quantitative Sandwich Enzyme Immunoassay (EIA)
• Serum and CSF are pre-treated to improve accuracy

The result is not intended to be used as the sole means for clinical diagnosis or patient management decisions.

• Very High: Blastomyces, Histoplasma, Paracoccidioides and Talaromyces (talaromycosis, previously penicilliosis)
• Moderate: Coccidioides
• Rare: Aspergillus
• None: Cryptococcus

• Sputolysin, sodium hydroxide and potassium hydroxide treatment degrade the analyte detected in the assay.

Testing is performed Monday – Saturday.

Results released: 24 – 48 hours

*New positives may require confirmation
