The contents of the nine biochemical tests may not be the same in different hospitals, usually including blood glucose, blood lipids, liver and kidney function, electrolytes and so on. Nine biochemical tests are not fixed items, but are chosen by the doctor according to the patient’s condition. If liver function is suspected to be abnormal, it can be checked for alanine aminotransferase, azelaic aminotransferase, total protein, gamma-glutamyltransferase, lactic acid dehydrogenase, and bilirubin. If you suspect abnormal renal function, check serum creatinine, urea nitrogen, uric acid and so on. In addition, blood glucose, blood lipids, electrolytes, etc. should be specifically selected according to the patient’s condition, and biochemical tests in some hospitals also include tumor marker tests. It is recommended to ask the doctor’s opinion and choose the appropriate biochemical test items.
