Infants who are infected with CMV after they are born rarely experience any long-term complications.
What is the normal range of CMV?
cmv viral load normal range The IgG for CMV normal range is 620 to 1400 mg/dl. If the reading is above this threshold, then you will need to consult a doctor to prevent any unwanted symptoms or infections.
Is cytomegalovirus an STD?
CMV can be sexually transmitted. It can also be transmitted via breast milk, transplanted organs and, rarely, blood transfusions. Although the virus is not highly contagious, it has been shown to spread in households and among young children in day care centers.
What is CMV in pregnancy?

How do you read CMV IgG results?
A high level of IgG is not as important as a rising level. If there is a 4-fold increase in IgG between the first and second sample, then you have an active CMV infection (primary or reactivated). A positive CMV IgM and negative IgG means you may have very recently been infected.
Does CMV shorten your life?

When do IgG antibodies mature after CMV infection?
IgG avidity testing may provide useful information regarding timing of infection. IgG antibodies produced following primary CMV infection have low avidity (low binding strength). Two to four months following infection, IgG antibodies mature to high-avidity (high binding strength).
What is the CPT code for CMV antibodies?
Lab Order Codes: CMV Synonyms: Anti -CMV Antibodies IgG and IgM ; CMV Serology; Cytomegalovirus Antibodies CPT Codes: 86644 –CMV antibodies (IgG) 86645 – CMV antibodies (IgM) Test Includes: Anti-CMV Antibodies, IgG and IgM
When to use seroconversion to test for CMV?
This applies for persons ≥12 months of age when maternal antibodies are no longer present. Measurement of CMV IgG in paired samples taken one to three months apart can be used to diagnose primary infection; seroconversion (1 st sample IgG negative, 2 nd sample IgG positive) is clear evidence for recent primary infection.
