Intended Use

The SPIFE LD test system can be used in conjunction with CK isoenzyme studies to aid in the diagnosis of myocardial infarction. The LD1/LD2 "flip" can be present in patients after acute MI, severe anemias, renal necrosis and in-vivo or in-vitro hemolysis of any cause.

The LD5 is increased in skeletal muscle injury or diseases, cirrhosis, hepatitis and passive liver congestion.

Mid-zone fractions (LD2,3,4) are increased in cases of massive platelet destruction (pulmonary embolism) and in lymphatic system involvements such as mononucleosis, lymphomas and lymphocytic leukemias.
