what do elevated levels of igm in a blood test mean?

Question by spazzola.: what do elevated levels of igm in a blood test mean?
i’ve been having crazy joint pain and went in to get two blood tests. the first one, about four weeks ago, looked pretty much normal with my igm a little high. the second, which was a few days ago, showed elevated igm levels. what does this mean? currently my doctor is giving me antibiotics for lyme disease because he thinks there may have been a false negative both times but there was never a tick sooo. :P
