Diagnostic value of lactate dehydrogenase isoenzymes in cerebrospinal fluid.

To evaluate the diagnostic value of lactate dehydrogenase (LD) isoenzymes in cerebrospinal fluid (CSF), 93 consecutive CSF specimens were analyzed. These specimens were from patients of four categories: tumors, infections, hemorrhages, and others. It was found that the isoenzyme patterns overlapped among different categories, but they differed within each category and were thus helpful in differential diagnosis.
