Test Details
Methodology
Immunofluorescence (IFA)
Result Turnaround Time
3 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Special Instructions
If reflex test is performed, additional charges/CPT code(s) may apply.
Limitations
MOG IgG antibody titers may assist in monitoring disease course and prognosis, but their role is imperfect. Antibody titers may increase but may not be predictive of relapses or attacks. MOG IgG antibodies may become undetectable with immunosuppression, but this does not necessarily indicate clinical response.
Results should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically established diagnostic product or procedure.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
