- Patient Preparation
- Random urine.
- Specimen Preparation
- Transfer 2 mL urine to an ARUP Standard Transport Tube.
- Storage/Transport Temperature
- Unacceptable Conditions
- Specimens other than urine. Urine in boric acid. Serum; refer to test Histoplasma Antigen by EIA, Serum (ARUP test code 0092522).
- Ambient: Unacceptable; Refrigerated: 2 weeks; Frozen: 2 weeks (avoid repeated freeze/thaw cycles)
0.4-3.1 ng/mL=Detected (below the limit of quantification)
Greater than 20.0 ng/mL=Detected (above the limit of quantification)
The quantitative range of this assay is 3.2-20.0 ng/mL. Antigen concentrations between 0.4-3.1 or>20.0 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, and/or radiographic evidence, to aid in the diagnosis of histoplasmosis.
