Coccidioides Quantitative Antigen EIA (View in report form.)
|CERNER / EPIC MNEMONIC: |
|CPT CODE: |
|CDM NUMBER: |
|TEST INFORMATION: |
Intended use is as an aid in diagnosis of coccidioidomycosis or to monitor therapy.
|DAYS PERFORMED: |
Test performed Monday - Friday only.
|TURNAROUND TIME: |
2 - 7 days
|CONTAINER TYPE: |
Sealed sterile urine container (no preservative); red top Vacutainer tube or SST tube; sealed sterile cerebrospinal fluid collection tube; sealed sterile sputum or Leuken's container.
|SPECIMEN REQUIREMENTS: |
Urine, serum separated from the clot, plasma separated from the red cell layer, CSF, bronchial, or other sterile body fluid
|REJECTION CRITERIA: |
Inadequate specimen volume, particulate matter or viscosity that would not allow the specimen to be pipetted.
|MINIMUM VOLUME: |
|HANDLING INSTRUCTIONS: |
Store in refrigerator if not sent the same day as obtained.
|REFERENCE RANGE: |
Negative = None Detected, Low Positive = 0.1-1.2 ng/ml, Moderate Positive = 1.3-8.2 ng/ml, High Positive = Above the Limit of Quantification
|LIMITATIONS OF TEST: |
Cross-reactions occur in histoplasmosis and possibly blastomycosis. Sputolysin and NaOH treatment degrade the analyte detected in the assay. Negative results do not exclude coccidioidomycosis: testing both urine and serum offers the highest sensitivity.
