Lactate dehydrogenase 332 indicates that it is high, which indicates the possibility of liver damage and can also be caused by heart disease as well as malignant tumors. Lactate dehydrogenase is found in tissues and organs throughout the body, especially in the heart, liver, kidneys and muscles. The normal value of lactate dehydrogenase is 109 to 245 u/l, so lactate dehydrogenase 332 indicates a high level. High lactate dehydrogenase may occur when the patient develops blood disorders such as acute hepatitis, cirrhosis, leukemia, anemia or when malignant tumors are present. Lactate dehydrogenase may also be elevated in skeletal muscle injury, pulmonary infarction, myocardial infarction, and progressive myasthenia gravis. When the lactate dehydrogenase is found to be elevated, it is necessary to consult a doctor in time, make a clear diagnosis and follow the doctor’s instructions to standardize the treatment.
