This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
Negative fungal serology does not rule out the possibility of current infection. If Blastomyces antibodies are equivocal or positive by EIA then Blastomyces Immunodiffusion will be added. Additional charges apply.
