    I know on the test results that IGM comes first, produced during acute phase, then IGG is lasting immunity.

    However, through the FFC Tests:
    - I'm positive on IGG for M. Pnuemoniae, neg for IGM
    - I'm positive on IGG for Parvovirus, neg for IGM.

    Here's my issue, they tell I have parvovirus, not M. Pnuemoniae. Why do I have one not both??? Or do I have neither since I don't have IGM?

    Thanks!

    I remember hearing that IGG means past( as it had the illness at one time during your life) and IGM means current.

    I could be very wrong, as my memory seems to have passed with this illness.

    It seems odd they would say you were positive for one with an IGG and not positive for the other.

    I hope someone writes in to clear this up, but I would definately check with the nurse at the FFC.

    my doc saying something about having an exceptionally high past infection reading, which she said could equate to a current active infection even though the current showed negative. there must be something more to reading the results than you would think. blessings. jen102

    I found local doctors who would help me with the Parvovirus.
