Expected turnaround time for a result, beginning when ARUP has received the specimen.
1-4 days
Reference Interval
Normal range/expected value(s) for a specific disease state. May also include abnormal ranges.
Not Detected
Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
The quantitative range of this assay is 0.19-60.0 ng/mL. Antigen concentrations less than 0.19ng/mL ;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.
Cross-reactivity 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.
Compliance Category
