What causes a consistently low c3c and c4c . they don't return to normal ever.
A doctor has provided 1 answer
Bad things: Since you had these labs drawn i assume you have symptoms to suggest that you have some diseass. If you do not have symptoms then i suggest these labs are not helpful and you should consider not drawing them. Most common cause is sle followed by vasculitis, autoimmune hemolytic anemia, cryoglobulinemia, and glomerulonephropathies.
