The MVista® Coccidioides Quantitative EIA test aids in the diagnosis of coccidioidomycosis (especially in seronegative cases). Monitoring the Coccidioides antigen helps in some cases to determine when treatment can be stopped and to diagnose relapse.
The result is not intended to be used as the sole means for clinical diagnosis or patient management decisions. Clinical sensitivity for diagnosis in dogs with pathology proven coccidioidomycosis is low (<40%); therefore, antibody testing is preferred for initial screening. Sputolysin, sodium hydroxide and potassium hydroxide treatment degrade the analyte detected in the assay.
Testing is performed Monday – Friday.
Results released: 24 – 48 hours
*New positives may require confirmation
None detected
Positive: 0.07 – 8.2 ng/mL
Positive Above the Limit of Quantification: Results greater than 8.2 ng/mL fall outside the linear range of the assay. These results are positive, but not accurately quantifiable.
