Patient's question:
NoDoctor's answer:
Isozymes of LDH have five forms, namely LDH-1 (H4), LDH-2 (H3M), LDH-3 (H2M2), LDH-4 (HM3), and LDH-5 (M4), which can be separated by electrophoresis. The distribution of LDH isozymes exhibits significant tissue specificity, so they can be used to assist in diagnosing diseases based on this specificity. In normal serum, LDH2 is greater than LDH1. If myocardial enzymes are released into the blood, LDH1 becomes greater than LDH2. This indicator can be used to observe and diagnose myocardial diseases.
