Rubella Virus - IgG

A Rubella Virus - IgG test is a blood test that helps detect the presence of immunoglobulin G (IgG) antibodies against the Rubella virus. It helps determine whether an individual has been previously exposed to the virus or vaccinated against rubella.

Rubella, also called German measles or 3-day measles, is a contagious viral infection caused by the Rubella virus. It usually causes mild symptoms such as fever, skin rash, headache, stuffy and runny nose, red itchy eyes, and general discomfort. However, it may pose a significant risk to unborn babies whose mothers become infected during pregnancy, and serious birth defects called congenital rubella syndrome (CRS) could develop, especially during the first trimester. Miscarriage and stillbirth are possible consequences for those who are pregnant. The vaccination to prevent rubella protects against these complications.

Rubella Virus - IgG test helps in determining an individual’s immune status regarding rubella, offering insights into whether they have acquired immunity through prior infection or vaccination. Doctors may also recommend this test in women before or in early pregnancy to ensure they are protected against rubella.  

No special preparation is required before undergoing a Rubella Virus - IgG test. However, it is important to inform your doctor about any medications, supplements, medical conditions, or vaccination history before the test as these factors may potentially influence the test results.

Retesting after 10 -14 days is suggested in individuals with negative results in suspected disease. 

Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation; therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results. The insights from this test help the doctor tailor an appropriate treatment plan.
