Reference Values
Reference Value: None Detected
Results reported as ng/mL in 0.2 - 14.7 ng/mL range
Results above the limit of detection but below 0.2 ng/mL are reported as 'Positive, Below the Limit of Quantification'
Results above 14.7 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 histoplasmosis, paracoccidioidomycosis, penicillosis, less frequently in coccidioidomycosis, rarely in aspergillosis, and possibly sporotrichosis.
