SLE pt. Bouts of pleurisy and pericarditis. Dr says I am now low on IgG and IgA. IgM on lower side of norm. Low C3 for yrs. Norm for lupus?

Lupus. Low C3 is expected in lupus due to disease activity and consuming up complement proteins cascade, which C3 is one of these proteins, the low immunoglobulins can very well be secondary to the immuosuppressants you're on, please keep a close follow up with your doctor and possibly an immnologist input would help, up to your rheumatologist .

I have a very high ANA titre (1:2560 homogenous), but normal immunoglobulins (IgG, IgA, and IgM) and normal CRP. Could I still have lupus?

False positive. Repeat the test. Other meds and conditions may cause this if the result is real and repeatable. If real and no other explanation, you need follow up by your doc as you may have an autoimmune disease that is too early to diagnose. Best wishes! Read more...
