LD-1 and LD-2 are both increased during myocardial infarction since they are both present in heart muscle. Hemolysis, both in vivo and in vitro, can also cause elevations in LD-1 and LD-2. Also in normal conditions, LD-2 is present in higher concentrations than LD-1. The reverse is true in myocardial infarction and during states of hemolysis. This term is referred to as the LD flip. Pancreatitis does cause increased levels of LD, but the LD-4 type is the most affected in this condition.
