The cost of biochemical examination varies from hospital to hospital, and the cost of a full biochemical examination at a tertiary hospital is about 300 yuan, including liver function, kidney function, blood glucose, lipids and ions. 1. liver function is mainly to detect various transaminases, including glutamic aminotransferase, glutamic oxalacetic aminotransferase, etc., to detect 2. liver function, including whether there is fatty liver, alcoholic liver or drug-related liver damage. 3. kidney function is mainly to determine kidney function by looking at creatinine and urea nitrogen. 4. 4, blood glucose is mainly used to diagnose diabetes, 5, blood lipids, including triglycerides, cholesterol, high-density lipoprotein and low-density lipoprotein commonly used. 6, ions in the biochemical coverage of potassium ions, sodium ions, chloride ions, calcium ions, especially in patients with heart disease to pay strict attention to the changes in potassium ions.
