Rubella Antibody, IgG
Also known as: RUBEIGG
Use
This test is used to determine the seroreactivity of women of childbearing age or provide evidence of vaccination/past infection against Rubella. An IgG antibody result of less than 9 IU/mL is considered not detected. Results between 9 and 9.9 IU/mL are indeterminate and may benefit from repeat testing in 10-14 days. Results of 10 IU/mL or greater are considered detected, indicating exposure to Rubella virus or vaccination.
Special Instructions
Parallel testing is preferred, and convalescent specimens must be received within 30 days from the receipt of the acute specimens. Label specimens as 'acute' or 'convalescent'.
Limitations
The magnitude of the measured result does not indicate the amount of antibody present. The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
