There should be reference ranges that are on that test as well. We need to see those.
I found this from Quest labs, but I don't know if that's who was used for your tests:
"≤0.90 Negative-No CMV IgG Antibody detected" for both the IgM and the IgG of the test
So for this example, your test values are insignificant as they are so far below the .90 value.
