Blastomyces dermatitidis Antibodies by EIA with Reflex to Immunodiffusion, Serum
Recommended test if serology is used to aid in the diagnosis of blastomycosis.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay/Qualitative Immunodiffusion
Serum Separator Tube (SST).
Separate from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.
