Test CodeSUHA
Quest Code
58792
CPT Codes
87385
Preferred Specimen
0.5 mL urine collected in a sterile, leak-proof container
Minimum Volume
Urine, BAL or other body fluids: 0.5 mL
CSF: 0.8 mL
Serum or plasma: 1.2 mL
CSF: 0.8 mL
Serum or plasma: 1.2 mL
Other Acceptable Specimens
1.2 mL plasma collected in an EDTA (lavender-top) tube, sodium heparin (green-top) tube, or 3.2% sodium citrate (light blue-top) tube • 1.2 mL serum • 0.8 mL CSF submitted in a sterile, leak-proof container • 0.5 mL bronchoalveolar lavage or body fluid submitted in a sterile, leak-proof container
Instructions
Indicate specimen type and date drawn on test request form. Two unique patient identifiers required on specimen container. Ship
to arrive Monday-Friday using a next day delivery service or 2nd day service. Do not ship by first class mail. List all antifungal agents patient is receiving.
Note: Interfering substances and cross-reactivities include sodium hydroxide and sputolysin. Cross-reactivity occurs between
blastomycosis and histoplasmosis and in paracoccidioidomycosis, penicillosis, coccidioidomycosis, aspergillosis and sporotrichosis.
Serum: Collect serum specimens in serum separator or red top tube. Allow blood to clot for 30 minutes, then centrifuge. Pipette serum into a plastic screw cap vial.
Plasma: Collect plasma specimens in an EDTA, heparin or sodium citrate tube. Centrifuge for 15 minutes and pipette plasma into a
plastic screw cap vial.
Urine/CSF/BAL/Other body fluid: Submit urine, CSF, BAL and all other body fluids in a sterile screw cap container.
