Collection Processing Instructions

​Ship to arrive Monday through Friday using a next day delivery service.  May ship sample at room temperature.  Do not ship by first class mail. 

Specimen Stability Information
Specimen TypeTemperatureTime
​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 

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
​None detected ​
Interpretation
  • Positive Below the Limit of Quantification: Results above the cutoff for positivity, but below 0.2 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable. Results will be confirmed and reported the next business day.
  • Positive: 0.2-14.7 ng/mL
  • Positive Above the Limit of Quantification: Results greater than 14.7 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.
