Anyone have Low Complement c4

[Pyr2]

Hi, just wondering if anyone had their complement levels checked? I have deficient C4 and low normal C3.

I have low C4 and C4a.
C3 and C3a are normal.

I too have low c4 and normal c3. I also have a low lymphocyte count.

I have C3 and C4 inbetween normal and low... what are your diagnosis/symptoms?
Docs are trying to decide if my issue is MCAD or some connective tissue disease and say that it should be low in the latter and probably normal in MCAD, but don't seem sure...

Who tested these where you are from immunologist?

My C4 was slightly low. Total complement and C3 were normal. The allergist was not concerned. She is however running other tests on me (7 tubes of blood worth).
