The result is not intended to be used as the sole means for the clinical diagnosis or patient management decisions.
Cross-reactions are seen with blastomycosis, paracoccidioidomycosis, penicilliosis, less frequently in coccidioidomycosis, rarely in aspergillosis and possibly sporotrichosis.
Sputolysin, sodium hydroxide and potassium hydroxide treatment degrade the analyte detected in the assay.
Quantitative Sandwich Enzyme Immunoassay (EIA)
Serum is pre-treated to improve sensitivity. This adds 1 day to TAT.
Positive samples may require confirmation which could extend TAT.
Positive: 0.20-20.00 ng/mL
Positive Above the Limit of Quantification: Results greater than 20.00 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.
