LDH isoenzymes
Alternate Names : LD, Lactic (lactate) dehydrogenase isoenzymes
What do Abnormal Results Mean?
Because LDH can be found in many tissues in the body, total LDH is not specific for heart disease. Normally, the level of LDH-2 is greater than LDH-1. However, after a heart attack, LDH-1 is generally higher than LDH-2. This is called a "flipped" LDH pattern. The LDH level rises within 24 - 72 hours after a heart attack, peaks in 3 - 4 days, and returns to normal in about 14 days.
Greater-than-normal LDH levels may suggest:
