Biochemical test report card usually has liver function, kidney function, blood lipid, blood sugar, uric acid, lactate dehydrogenase, creatine kinase and so on. Liver function refers to total protein, albumin, globulin, which reflect the synthesis function of the liver; alanine aminotransferase, glutamine aminotransferase, reflecting liver damage, especially alanine aminotransferase is sensitive to acute liver damage; total bilirubin, direct and indirect bilirubin, urinary bilirubin, blood bile acid, gamma-glutamyl transpeptidase and alkaline phosphatase, reflecting the metabolism of bilirubin and biliary sludge indicators. The renal function refers to the creatinine, the blood bilirubin, the gamma glutamyl transpeptidase and the alkaline phosphatase. Renal function refers to creatinine, urea nitrogen, serum creatinine concentration can reflect the degree of damage to glomerular filtration function; urea nitrogen can reflect the renal parenchyma is damaged. Lipids include total cholesterol, triglycerides, high and low density lipoproteins and apolipoproteins, which are essential for the basic metabolism of the human body, and their indicators can suggest the risk of hyperlipidemia, pancreatitis and cardiovascular disease. Uric acid is the end product of purine metabolism, and when high, it can indicate hyperuricemia. Lactate dehydrogenase is a class of NAD-dependent kinase, which is present in almost all tissues, most abundant in heart, skeletal muscle and kidney, followed by liver, spleen, pancreas, brain, lungs, etc. Elevated indexes can indicate myocardial infarction, liver disease, bone injury, metastasis of malignant tumors and so on. Creatine kinase is an important kinase directly related to intracellular energy operation, muscle contraction and ATP regeneration, and its index can be used for the diagnosis of skeletal muscle diseases and cardiac muscle diseases. If the biochemical report is abnormal, it is necessary to consult a doctor in time, and the professional doctor will further investigate the related diseases according to the abnormal indexes, so as to avoid delaying the condition.
