Quantitative Enzyme Immunoassay
Mon, Wed, Fri
Plain Red or Serum Separator Tube (SST).
Transfer 2 mL serum to a sterile ARUP Standard Transport Tube (ARUP Supply #43115). (Min: 1 mL)
Specimen types other than those listed.
Ambient: Unacceptable; Refrigerated: 2 weeks; Frozen: 1 month (avoid repeated freeze/thaw cycles)
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.
