Serologic Testing

Slide 11

July 2008

Because of this, Mayo Medical Laboratories has discontinued all serologic testing for IgM-class antibodies to Rubella. This decision was based on several factors, including:

  • The absence of endemic transmission of the disease in the United States as determined by the CDC;
  • The high rate of vaccine coverage (>95%) among school-aged children;
  • The high level of immunity in this country; and finally,
  • The potential negative impact of false-positive Rubella IgM result.

Although it’s not recommended, Rubella IgM testing is often performed prenatally in asymptomatic pregnant women. In this setting, a false-positive result may generate substantial worry to parents, needless follow-up testing, needless expenditure of resources, and potentially the termination of healthy pregnancies.
