​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.

Test Information

Positive samples may require confirmation which could extend TAT.

Reference Range Information
​None Detected
Interpretation

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.
