LDH isoenzymes |
| Overview Risks Results |
| Alternative Names: |
| LD; Lactic (lactate) dehydrogenase isoenzymes |
| What abnormal results mean: |
| Because LDH can be found in many tissues in the body, total LDH is not specific for heart disease. Normally, the concentration of LDH-2 is greater than LDH-1. However, after a heart attack, the concentration of LDH-1 is generally higher than that of LDH-2. (This is called a "flipped" LDH pattern.) The LDH level rises within 24 to 72 hours after a heart attack, peaks in 3 to 4 days, and returns to normal in about 14 days. Greater-than-normal LDH isoenzyme levels may be seen in:
