Rubella IgM Test. Prices, Reviews, Ratings
IgM antibodies are specific immunoglobulins produced in the human body during acute clinical manifestations of infection. They serve as a serological indicator of rubella. These antibodies are produced upon infection. IgM appears immediately, as the protein content in the blood rises significantly within 10 days of infection and then declines over several weeks. In newborns, IgM-class antibodies are detectable for six months to a year.

What is the Rubella IgM Test
The rubella virus affects unvaccinated children under 8 years old. Primary transmission routes are airborne, contact (via household items), and vertical (through the mother’s placenta). The incubation period ranges from 15 to 24 days. Symptoms include fever, runny nose, enlarged lymph nodes in the neck, armpits, and groin, a fine rash on the body, and changes in eye color. Children tolerate the infection easily, with no complications.
As rubella is classified as a TORCH infection, it poses risks of irreversible fetal developmental pathologies (e.g., congenital rubella syndrome). Affected children may be born with cataracts, deafness, muteness, heart and liver defects, and later exhibit mental and physical retardation. The test is ordered by a general practitioner, infectious disease specialist, or gynecologist. If neither IgG nor IgM is detected in the blood, vaccination is recommended. Venous blood is used as the biomaterial.
Indications for Rubella IgM Blood Test
The test is necessary for:
- Checking immunity to the rubella virus;
- Planning conception;
- Infants with heart, vision, hearing, CNS, or other anomalies linked to congenital rubella syndrome;
- Pregnant women experiencing headaches, fever, reddish rashes on the face and abdomen, or fever;
- Unexplained enlargement of lymph nodes;
- Infectious diseases.
Note that a false-positive result may occur due to IgM cross-reacting with other blood proteins. For accurate results, test for baseline IgG levels, then repeat the test after 24-30 days to assess changes over time.
How the Rubella IgM Test Is Performed
The test is conducted on an empty stomach in the morning. Avoid hormonal or medicinal drugs 24 hours prior and refrain from smoking.
Result interpretation:
- IgM– IgG–: The patient has never had rubella. Vaccination is needed before 20 weeks if planning pregnancy.
- IgM– IgG+: Immunity to rubella exists. No repeat test is needed. No risk of infection during pregnancy.
- IgM+ IgG–: Early-stage disease.
- IgM+ IgG+: Acute rubella.
Avidity below 50% indicates acute inflammation; equal avidity is inconclusive, requiring a retest in 12-14 days; above 50% signifies immunity.
The accuracy of the test results largely depends on proper sample collection and preparation techniques.
