My rubella test came back positive, i was told that this is a good thing. is this true?

Yes: It usually means you have a positve antibody titer to the rubella virus, suggesting you have immunity.

No,indicates imunit: A positive test for rubella immunity indicates your body has been exposed to wild rubella or the rubella vaccine & developed protective antibodies to it. If you are female, it means you will not pass rubella to your fetus if u are exposed to the illness during pregnancy & get the disease.

It means...: That you are immune to rubella.

YES: If your rubella igg serology (which they probably checked) was positive this indicates immunity and that is a good thing. If you are igg negative, your should get the rubella immunization when you are no longer pregnant.
