Dermatophyte Antibody, Cerebrospinal Fluid
Detects antibodies to dermatophyte fungi in cerebrospinal fluid. It may help support evaluation for a suspected fungal infection involving the nervous system.
["A positive result can support a dermatophyte fungal infection affecting the central nervous system."]

What is this test?
This test looks for antibodies against dermatophyte fungi in cerebrospinal fluid, the fluid surrounding the brain and spinal cord. Antibodies are proteins made by the immune system in response to an infection.
Why might I need this test?
It may be considered when symptoms suggest a fungal infection involving the brain or spinal cord. Because dermatophyte antibody testing in cerebrospinal fluid is uncommon, results are usually interpreted with other laboratory findings, cultures, imaging, and the clinical situation.
How is the test performed?
Cerebrospinal fluid is usually collected by lumbar puncture, also called a spinal tap. A laboratory then tests the fluid for dermatophyte antibodies using an appropriate antibody-detection method.
How do I prepare for the test?
No fasting or medication changes are generally required for this laboratory test. If a lumbar puncture is needed, your clinician will explain the procedure, positioning, and possible risks before it is performed.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Detectable dermatophyte antibodies in cerebrospinal fluid may support an infection caused by a dermatophyte fungus, particularly if the result is consistent with the symptoms and other findings. A negative result does not completely exclude infection, and antibody results may also reflect exposure without active disease. Interpretation should be made by a clinician familiar with the specimen and testing method.
Short name
Dermatophyte antibody (CSF)
