[Use of the antibody neutralization test for detecting myoglobin in the urine in the diagnosis of myocardial infarction].

A total of 230 patients admitted to Moscow city hospitals were examined to study the diagnostic value of a kit "Diagnosticum for the detection of erythrocytic myoglobin, dry". Myocardial infarction was diagnosed in 165 of them: in 138 it was transmural, in 27 intramural and in 65 the diagnosis was not confirmed (they were entered into the control group). Myoglobinuria was detected on the 1st day of transmural MI in 95%, on the 2nd day in 92% and on the 3rd day in 82%. In patients with intramural MI myoglobinuria was noted in 72% of the cases. In the control group the test was false positive in 9%.
