Aids in the diagnosis of histoplasmosis. May also detect blastomycosis and coccidioidomycosis. Testing in conjunction with Histoplasma Antibodies by Complement Fixation and Immunodiffusion (0050627) and Histoplasma Antigen Quantitative by EIA, Serum (0092522) is recommended.

Specimen Required
Patient Preparation
Collect
Random urine.
Specimen Preparation
Transfer 2 mL urine to an ARUP standard transport tube.
Storage/Transport Temperature
Refrigerated.
Unacceptable Conditions
Specimens other than urine. Urine in boric acid. Serum; refer to test Histoplasma Antigen by EIA, Serum (ARUP test code 0092522).

Not Detected
Interpretive Data
Background information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
Less than 0.4 ng/ml = Not Detected 0.4-0.7 ng/mL = Detected (below the limit of quantification) 0.8-24.0 ng/mL = Detected Greater than 24.0 ng/mL = Detected (above the limit of quantification)
The quantitative range of this assay is 0.8-24.0 ng/mL. Antigen concentrations between 0.4-0.7 or >24.0 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.
