Text: LD is released from the cells into the bloodstream when cells are damaged or destroyed. Due to this, the LD test can be used as a general marker of injury to cells. Changes of LD isoenzymes periodically measured following onset of chest pain provide information for the differential diagnosis of acute infarct of myocardium.
