What does CMV IgG AB positive mean?
A positive test for CMV IgG indicates that a person was infected with CMV at some time during their life but does not indicate when a person was infected. This applies for persons ≥12 months of age when maternal antibodies are no longer present.
What causes cytomegalovirus IgG?
Touching your eyes or the inside of your nose or mouth after coming into contact with the body fluids of an infected person. Sexual contact with an infected person. The breast milk of an infected mother. Organ, bone marrow or stem cell transplantation or blood transfusions.
What does positive cytomegalovirus IgM mean?
Positive CMV IgM results indicate a recent infection (primary, reactivation, or reinfection). IgM antibody responses in secondary (reactivation) CMV infections have been demonstrated in some CMV mononucleosis patients, in a few pregnant women, and in renal and cardiac transplant patients.
What happens if cytomegalovirus IGG is high?
If your results are higher, it may also mean that you have a connective tissue autoimmune disease, such as rheumatoid arthritis or systemic lupus erythematosus. If your immune system is weakened, you may have lower results even with an active infection.
How does a person get CMV?

CMV infection can be contagious if the infected person comes in close or intimate contact with another person. You should avoid kissing and sexual contact with an infected person. The virus may also spread among young children in day care settings.
Does IgG show immunity?
The persistence of spike antigen-specific serum IgG following vaccination is hopefully a positive indicator of effective long-lived immunity, and clinical indicator of vaccine responsiveness . In addition to IgG, the data demonstrate COVID-19 mRNA vaccines also elicit antigen-specific IgA, which may be important in preventing transmission as well as infection [ 28 , 29 ].
