A member asked:

I have low c3 and c4 with high histamine levels. what could be the cause?

A doctor has provided 1 answer

See details: Low C3 and C4 can be seen in numerous conditions or may have no clinical importance at all. The conditions you list would not cause the low values. Why were the tests ordered in the first place? You should address this question to the doctor who ordered the tests.
