title: [Interference by glutathione reductase in the "CK-MB-inhibition-test": elimination of the catalytic activity of glutathione reductase by anti-glutathione reductase (author's transl)].
abstract: Glutathione reductase interferes in the determiniation of creatine kinase-MB by the "CK-MB-inhibition-test". In 36 out of 55 serum samples with normal and elevated catalytic activities of creatine kinase, "negative" values greater than 14 U/l were obtained for the creatine kinase-MB. This interference by glutathione reductase is avoided by preincubation of the serum samples for 5 min with anti-glutathione reductase.
