A member asked:
Possible to have lupus flare when c3 &c4 are normal? my md diagnosed me based on other criteria (c3 &c4 were normal) but now he bases flares on c3, c4
A doctor has provided 1 answer
Yes: Remember that the range of C3 & C4 is relatively wide. In fact, the % drop in C3 & C4 may be more helpful than the absolute measurements alone. Follow your rheumatologist's instructions.
