The quantitative range of this assay is 0.19-60.0 ng/mL. Antigen concentrations less than 0.19ng/mL or greater than 60.0 ng/mL fall outside the linear range of the assay and cannot be accurately quantified.
This EIA test should be used in conjunction with other diagnostic procedures, including microbiological culture, histological examination of biopsy samples, serology and/or radiographic evidence, to aid in the diagnosis of histoplasmosis.
Crossreactivity with Blastomyces dermatiditis, Coccidioides immitis, and possibly Talaromyces marneffei have been observed with this EIA. Other clinically and geographically relevant endemic mycoses should be considered in the case of a positive test result.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
