FAQs
It may suggest recent or reactivated infection, but IgM can be non-specific and requires clinical interpretation.
No.
No. Clinicians often use IgG, avidity, and/or PCR depending on context.
IgG avidity can help estimate timing of infection in some scenarios, especially in pregnancy workups.
Often same day or within 24 hours.
Serum blood sample.
Yes in many serviceable areas.
Consult your obstetrician promptly for appropriate confirmatory testing and counseling.
It can persist; that’s why confirmatory approaches are used.
Yes, especially in immunocompromised states; clinicians may use PCR to assess activity.
No. Treatment decisions are clinician-led, particularly in pregnancy and immunocompromised patients.
