Complement C4a Results


Senior Member
Hi all. Just wanted to share some test results.

Almost exactly two years ago, I had my C4a tested, and it was 17728 (normal: 0 - 2830).

Now, after over a year of Lyme-related treatment under Dr. DeMeirleir, my C4a is 9025.

I am definitely still very sick and mostly housebound, but in much less agony than I was 2 years ago...so perhaps I am on the right track.

I read that C3a elevation along with C4a elevation could indicate some form of autoimmune disease, but my C3a is normal..
