What are the Normal Values for Blood Biochemistry Tests?

The main items of blood biochemistry examination include liver function, kidney function, blood sugar, blood lipids, ion analysis, etc. Among them, the normal range of transaminase is 0~40U/L, the normal range of total protein is 64~83g/L, the normal range of albumin is 35~55g/L, the normal range of globulin is 20~45g/L, and the normal range of albumin to globulin ratio is 1.2~2.5. The normal range of total bilirubin is 3.4~20.5ummol/L, the normal range of direct bilirubin is 0~6.8umol/L, the normal range of indirect bilirubin is 0~17umol/L, the normal range of alkaline phosphatase is 42~98U/L, and the normal range of glutamyl transpeptidase is 0~54U/L. The normal range of urea is 2.6~8mmol/L. The normal range of creatinine is 44~110umol/L, the normal range of β2-microglobulin is 1~3mg/L, the normal range of uric acid is 154.7~357umol/L, and the normal range of glucose is 13.9~6.1mmol/L. The normal range of total cholesterol is 3.1~5.7mmol/L. The normal range of triglycerides is 0.7~2.2mmol/L. There are various clinical blood biochemistry examination items, including: 1. Blood lipid examination, including triglycerides, cholesterol, and various lipoproteins. 2. Liver function examination, including the concentrations of various transaminases, bilirubin, alkaline phosphatase, and lactic dehydrogenase. 3. Renal function examination, including creatinine, urea nitrogen, and uric acid concentrations. 4. Examination of various ions, including the concentrations of potassium, calcium, sodium, and chloride ions, as well as the examination of serum iron, ferritin, and total iron binding capacity. 5. Various endocrine examinations, such as catecholamine concentration examination. Before the blood biochemistry examination, it is recommended that patients refrain from eating and drinking after 12 pm on the day before the blood routine examination, as eating and drinking can affect the results of the blood biochemistry examination. Drinking water can lead to blood dilution, resulting in a decrease in all blood biochemistry indicators. Additionally, diet, especially high-fat and high-protein diets, may affect the liver function results in the blood biochemistry examination. Therefore, it is recommended that patients refrain from eating and drinking after 12 pm on the day before the blood biochemistry examination to ensure the accuracy of the blood biochemistry examination on the following day.
