Test includes: |
Qualitative determination of IgM antibodies to cytomegalovirus. | ||||||||
Methodology: |
Chemiluminescence |
||||||||
Synonyms: |
CMV IgM, Cytomegalovirus IgM, CMVM, TORCH CMV IGM AB, Cytomegalovirus antibody IgM
|
||||||||
Clinical significance: |
Cytomegalovirus (CMV) exposure occurs throughout life, and by adulthood 50-90% of the population is seropositive for CMV antibodies. A single positive CMV IgG result is useful in distinguishing subjects who have been exposed to the virus from those who have not and by itself is indicative of a prior infection. Testing for CMV IgM antibodies is recommended to support a diagnosis of a current infection. | ||||||||
