A member asked:
Dr is looking for lupus since i have many symptoms. my ana is a low positive and c3 is 73. what is the normal range for c3?
A doctor has provided 1 answer
Yours is near normal: The first site listed below provides information about C3. The second one has information about diagnostic criteria for SLE. It needs multiple factors to make SLE. http://www.nlm.nih.gov/medlineplus/ency/article/003539.htm http://lupusresearchinstitute.org/lupus-facts/lupus-diagnosis
