Reference Values
Reference interval: None Detected
Results reported as ng/mL in 0.4 – 19 ng/mL range
Results above the limit of detection but below 0.4 ng/mL are reported as Positive, Below the Limit of Quantification.
Results above 19.0 ng/mL are reported as ‘Positive, Above the Limit of Quantification’
Cautions
Interfering Substances & Cross-Reactivities:
Sputolysin, sodium hydroxide and potassium hydroxide treatment degrade the analyte detected in the assay. Cross-reactions are seen with blastomycosis, paracoccidioidomycosis, penicilliosis, less frequently in coccidioidomycosis, rarely in aspergillosis, and possibly sporotrichosis.
