What is the advantage of CK estimation over LDH estimation to identify myocardial infarction?

Description : What is the advantage of CK estimation over LDH estimation to identify myocardial infarction?

Last Answer : The CK level starts to rise within three hours of infarction. Therefore, CK estimation is very useful to detect early cases, where ECG changes may be ambiguous. The CK level is not increased in hemolysis or in congestive cardiac failure; and therefore CK has an advantage over LDH.
