Coccidioides Canine Antibody IgG EIA

• Test Information
• Specimen Requirements
• Shipping Information

• Test Code +

  329

  Clinical Significance +

  The presence of IgG to Coccidioides assists in the diagnosis of coccidioidomycosis in dogs.  IgG may be detected in some healthy dogs from the endemic area as a result of sub-clinical infection within the last 2 years.  Intermediate results (8-9.9 EU) typically reflect either rising or falling IgG, and retesting the patient in several weeks may be beneficial.

  Methodology +

  Semi-Quantitative Indirect Enzyme Immunoassay (EIA)

  Limitations +

  Cross-reactivity/False Positives: Low: Histoplasma, Blastomyces, and Coccidioides (true positives are considerably higher than cross-reactive results)

  The reference range and other method performance specifications have not been established for this test in CSF. The test results should be integrated into the clinical context for interpretation.

  Turnaround Time +

  Testing is performed Wednesday & Friday.
