Blood biochemistry tests include many items. The cost of a general blood biochemistry (liver and kidney function, blood lipids and glucose, electrolytes, cardiac enzymes) test is about $300 to $500, and health insurance can reimburse you for even less. The most complete biochemistry test can cost up to 1,000 yuan, and physicians need to select the items to be checked according to the patient’s situation. The more items to be checked, the more expensive it is. A brief introduction to the general items of blood biochemistry, including liver function tests, blood glucose measurement, blood lipid measurement, kidney function tests, electrolyte measurement, and cardiac enzyme profiling. 1. Liver function tests: including serum total bilirubin, serum direct bilirubin, indirect bilirubin, serum aspartate aminotransferase, etc., which can be used to observe whether the liver cells are damaged and whether there is acute or chronic hepatitis. 2. Renal function tests: including urea measurement, creatinine measurement, glomerular filtration rate measurement, etc., which can help diagnose nephritis and renal failure and other diseases. 3. Electrolyte indicators: including potassium ionization, sodium ionization, chloride ionization, calcium ionization, etc., which can observe whether there is any obstacle in the metabolism of substances in the body. 4. Lipid test: including serum triglyceride measurement, serum high-density lipoprotein measurement, serum cholesterol measurement, etc., which can check whether there is hyperlipidemia. 5. Blood glucose measurement: generally fasting blood glucose measurement, can detect the existence of diabetes and other conditions. 6. Myocardial enzyme profile: including lactate dehydrogenase measurement, serum creatine kinase measurement, etc. It can observe whether there is myocardial injury. It can observe whether there is any myocardial damage. The pricing of the tests varies with the level of the hospital or province, and also with the use of different reagent kits, but the price difference is not significant.
