Have lupus. being tested for possible autoimmune liver diseases. recent blood work showed immunoglobulin m elevated at 470 (range 26-217). ?

See below: 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.
