Serum lactate dehydrogenase isoenzymes in the diagnosis of myocardial infarction.
The ratio of lactate dehydrogenase (LD-1:LD-2) in serum was studied in 101 patients admitted to a coronary care unit. The clinical reliability of the test could not be predicted from the normality or abnormality of the total serum lactate dehydrogenase (LD) activity. However, for samples with total LD activity below the middle of the normal range, no information was provided by the test. In contrast, the test provided reliable information when the total LD activity in the specimen was above the middle of the reference range (220 IU per L).
