IgM antibodies to varicella-zoster virus, qualitative (Anti-Varicella-Zoster Virus IgM, Qualitative, Serum)
The study is aimed at detection of acute Varicella-Zoster virus infection. Used for diagnosis of chickenpox and shingles. Helps identify the active phase of infection and distinguish it from past illness or vaccinated status. Prescribed when fever, rash, and pain in dermatome areas appear, especially in children and pregnant women.
What the test evaluates:
- Presence of IgM antibodies to VZV
- Active phase of the infectious process
- Diagnostic information on primary infection and its dynamics
Biomaterial: Venous blood (serum)
- Draw blood fasting (8-12 hours after last meal)
- Still water is permitted
Medications:
Antiviral drugs and immunoglobulins may affect results
Other medications generally do not affect results; inform physician of all medications taken
Recommended for:
- Suspected acute infection
- Fever, rash, and intoxication symptoms
- Children with clinical signs of chickenpox or shingles
- Suspected acute infection during pregnancy
Positive result: indicates active or recent VZV infection
Negative result: active infection unlikely; clinical data and IgG status considered
Note: During pregnancy, physician consultation is necessary to assess fetal risk.
