Specimen Stability Information

Specimen Type	Temperature	Time
CSF or BAL	Room Temperature	14 days
	Refrigerate (preferred)	14 days
	Frozen	Indefinite

Rejection Criteria

Tissue, Sputum, Bronchial Brushings, Stool, FNA, Biopsy, Tracheal or Bone Marrow Aspirate
Stored in Transport Media, Fixative or Isolator Tubes
Specimen is too viscous to pipette

Interference

Sputolysin, sodium hydroxide and potassium hydroxide degrade the analyte detected in the assay.

Cross-reactivity occurs between blastomycosis and histoplasmosis and in paracoccidioidomycosis, penicillosis, coccidioidomycosis, aspergillosis and sporotrichosis.

Test Information

Positive samples may require confirmation which could extend TAT.

Reference Range Information

Reference Interval: None Detected Reportable Range: 0.31 ng/mL – 20.00 ng/mL Results above 20.00 ng/mL are reported as 'Positive, Above the Limit of Quantification'

Interpretation

None Detected: <0.31 ng/mL
Positive: ≥0.31 ng/mL – 20.00 ng/mL
Positive Above the Limit of Quantifications
Results greater than 20.00 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.

Results should be correlated with clinical presentation and history
