Biochemical blood tests generally refer to blood biochemistry. Blood biochemical tests include blood glucose, blood lipids, serum enzymes, bilirubin, etc., which can help clinically determine the condition and monitor the treatment effect. 1. Blood glucose: Adults in the fasting state, the normal blood glucose value is 3.9-6.1mmol/l, fasting whole blood glucose ≥6.7mmol/l, plasma glucose ≥7.8mmol/l, 2 times repeated determination can be diagnosed as diabetes mellitus. 2. Lipids: Lipids include cholesterol, triglycerides, phospholipids and free fatty acids, of which the normal values of cholesterol are 2.84-5.68mmol/l and triglycerides are 0.56-1.7mmol/l. Elevated plasma levels of cholesterol or triglycerides are considered hyperlipidemia. 3. Serum enzymes: including alanine aminotransferase, glutamate aminotransferase, aspartate aminotransferase, etc. Changes in the activity of serum enzymes can help to reflect the pathological state of the liver, and it is one of the commonly used methods for liver function tests. 4. Bilirubin: Bilirubin is an important basis for clinical determination of jaundice and an important indicator of liver function. In addition, blood biochemistry test also includes renal function test such as creatinine, urea nitrogen, uric acid concentration, and various ion tests, such as potassium ion, sodium ion, calcium ion, chloride ion concentration and so on. If the test results are abnormal, you should consult a doctor in time.
