|3000230||Fungal Antibodies with Reflex to Blastomyces dermatitidis Antibodies by Immunodiffusion, CSF||0.9 IV or less: Negative
1.0-1.4 IV: Equivocal
1.5 IV or greater: Positive
|Blastomyces Ab by Immunodiffusion, CSF||None Detected|
Refer to Report
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.
