Hello,
To the question "What does Rubella IgG 28.58 and Rubella IgM 0.141 in a blood test mean?", the doctor would like to answer as follows:
Rubella is a benign but serious typhus disease. for pregnancy. Pregnant women infected with Rubella in the first trimester, up to 90% of mothers can pass the virus to their babies, causing congenital rubella syndrome. Therefore, it is very important that Rubella is diagnosed and tested in the first 3 months. IgG and IgM are two types of Rubella antibodies produced by the body's immune system against Rubella disease. When the Rubella virus enters the body, IgM antibodies appear first and then disappear after 8 weeks. IgG antibodies appear later and persist for as long as the virus was present at some point in time. If the patient is reinfected, only the IgG index will increase. Usually, the Rubella test is done when the fetus is 10-12 weeks old. Besides, Rubella IgG 28.58 and Rubella IgM 0.141 mean IgM negative and IgG positive. You have had Rubella infection for at least 10 weeks before and already have protective antibodies.
The doctor can only answer if you have ever been vaccinated or have been infected with Rubella in the past, but cannot determine the exact time. First of all, you should monitor your pregnancy on regular morphological ultrasound. If you have been infected with Rubella from infancy to now, have formed antibodies, IgG and IgM are negative, the only way is to test the amniotic fluid for the virus.
If you still have questions about Rubella IgG and Rubella IgM, you can go to a hospital of Vinmec Health System for testing and further advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
