Interpretive Data
The quantitative range of this assay is 1.25-200 U/mL. Antigen concentrations less than 1.25 U/mL or greater than 200 U/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 blastomycosis.
Cross-reactivity with other endemic mycoses (Histoplasma and Coccidioides) may occur. Positive test results should be correlated with other clinical findings and relevant exposure history.
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.
