Tissue, Sputum, Bronchial Brushings, Stool, FNA, Biopsy, Tracheal or Bone Marrow Aspirate
Stored in Transport Media, Fixative or Isolator Tubes
Test Information
Positive samples may require confirmation which could extend TAT.
Interferences
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.
Interpretations
Reference Interval: None Detected
Reportable Range: Positive: 0.20 ng/mL to 20.00 ng/mL
Positive results above 20.00 ng/mL are reported as "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.
Cross-reactions occur with blastomyces spp., Coccidioides spp., and Paracoccidioides brasiliensis
