Lactate Dehydrogenase (LDH)- Lactate dehydrogenase (LDH) is an important enzyme that helps with cellular respiration, the process through which your body transforms glucose (sugar) from the food you eat into energy for your cells. Enzymes are proteins that help speed up metabolism, or the chemical reactions in your body. Complete Blood Count (CBC)- A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including Red blood cells, which carry oxygen. Creatine Phosphokinase-MB (CPK-MB)- Abstract. Creatine phosphokinase-MB (CPK-MB) is the most sensitive and the most specific indicator available for the diagnosis of an acute myocardial infarction. Total Creatine Phosphokinase (CPK)- When the total CPK level is very high, it most often means there has been injury or stress to muscle tissue, the heart, or the brain. Muscle tissue injury is most likely. When a muscle is damaged, CPK leaks into the bloodstream. Finding which specific form of CPK is high helps determine which tissue has been damaged. SGPT- SGPT is a quick test measured through blood samples to monitor the health of your liver. The test can identify the presence of high levels of SGPT enzyme that can be indicative of many conditions such as liver disorders, hepatitis, and jaundice.
