Not recommended as a stand-alone test. Refer to Blastomyces dermatitidis Antibodies by EIA with Reflex to Immunodiffusion, Serum (3000236).
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.15 mL)
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
A positive result may suggest active or recent infection. The test is positive in about 80% of cases. Cross-reactions occur, especially with histoplasmosis. A negative test (none detected) does not exclude blastomycosis.
This test uses a partially purified "A" antigen of Blastomyces dermatitidis.
