Blastomyces dermatitidis Antibodies by Immunoassay with Reflex to Immunodiffusion, CSF
Also known as: BLST R CSF
Use
This test is used to detect antibodies against Blastomyces dermatitidis in cerebrospinal fluid (CSF). It is intended for the diagnosis of blastomycosis, a fungal infection caused by Blastomyces species. Detection of antibodies in CSF can aid in diagnosing central nervous system involvement in blastomycosis. It is recommended to consider this test in conjunction with histology or culture for a comprehensive diagnostic approach.
Special Instructions
Not provided.
Limitations
The test detects total antibodies against yeast-phase antigens from Blastomyces dermatitidis. An elevated EIA result combined with a negative immunodiffusion result may indicate an early infection or a falsely elevated EIA result, suggesting the need for repeat testing. It is important to note that a negative immunodiffusion result does not exclude the possibility of infection.
