Myoglobinaemia in Duchenne muscular dystrophy patients and carriers: A new adjunct to carrier detection.

Myoglobinaemia was detected in 14 of 18 patients with Duchenne muscular dystrophy (D.M.D.) with a sensitive specific complement-fixation assay. Myoglobinaemia was also detected in 10 of 16 known D.M.D. carriers, including 4 with normal serum-creatine-phosphokinase activity. 9 of 27 possible carriers also had myoglobinaemia. It is suggested that this assay is a useful adjunct to present methods of carrier detection in D.M.D.
