What is the Rubella IgG Test (Rubella virus)
The Rubella virus, the causative agent of rubella, is a viral infectious disease. Children under 8 are at risk. The disease is most dangerous for pregnant women, with a high likelihood of intrauterine fetal death, preterm labor, and severe fetal pathologies, as rubella is part of the TORCH infections. Women are advised to test for IgG 2-3 months before planning conception. If pregnancy is unplanned, preventive or therapeutic measures should be taken in the first trimester. Adults generally experience the disease more severely than children. Venous blood is used as the biomaterial.
IgG antibodies are produced a month after infection and persist lifelong to prevent recurrence. If anti-Rubella-IgG concentration in venous blood is below 10 IU/mL, immunity cannot resist the virus. A higher value indicates resistance. The test can be repeated every few weeks to monitor changes dynamically. An additional parameter, anti-Rubella-IgM, is used. A steady rise in IgG titers confirms acute infection. In newborns, umbilical cord blood is tested, as the virus can cross the placenta.
Rubella spreads via airborne droplets and transplacentally. The incubation period is 15-21 days. It begins with a fine red rash behind the ears, on the neck, and face, later spreading to the limbs and body. Fever rises to 38-39°C, accompanied by joint discomfort, bone aches, reddened eyes, and enlarged lymph nodes. In children, it resolves in days; adults may face complications like polyarthritis or encephalitis, with a 20-40% fatality rate. Transplacental transmission risks congenital rubella syndrome (CRS), leading to cataracts, deafness, heart, kidney, and liver defects, and potential mental and physical retardation.
A pediatrician, gynecologist, or infectious disease specialist may order this lab test. If no IgG or IgM antibodies are found in the blood serum, vaccination is needed.

How the Rubella IgG Test (Rubella virus) Is Performed
Blood is drawn in the morning on an empty stomach. Avoid smoking 30 minutes prior and refrain from medicinal or hormonal drugs to ensure accurate, undistorted results.
In the lab, a tourniquet is applied to the forearm to highlight veins. A sterile disposable needle punctures the vein, blood is collected, and the site is swabbed with an alcohol-soaked cotton pad. The sample is analyzed using a specific test system.
