Complex issue. Yes, your Dr is probably right and trivial elevation of CH50 is probably due to ongoing pro-inflammatory state due to underlying autoimmune disease. Need to speak with a Rheumatologist

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your issue is more complex that is feasible to address in this forum. Wish you good health!
