Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
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.
