Quizplus · Accepted Answer

The presence of rubella IgM and IgG antibodies suggests an acute infection with rubella virus. The negative results for measles and varicella-zoster IgM antibodies indicate that these viruses are not the cause of the patient's symptoms. The negative results for varicella-zoster IgG antibodies suggest that the patient is not immune to this virus.
