Is your health at risk if your lactate dehydrogenase is above normal level?

There are several enzyme levels in the body that are only indicative of illnesses when taken in context with other abnormal labs. Examples of these would be LDH, CRP and alkaline phosphatase. These tests are more useful in confirming the diagnosis determined from more specific tests as no abnormalities in liver, heart or muscles. We would need to look at the full panel of lab tests to determine if an elevated LDH level was significant.
