The price of a full set of biochemical tests is about 400 yuan, but of course the price of a full set of biochemical tests may vary from hospital to hospital, with different equipment and different reagents. When taking blood for biochemical examination, absolute fasting is required, that is, no food or water after 10 o’clock at night, and the blood will be drawn at around 6 o’clock in the morning of the second day, because if water or food is taken, it may have an effect on liver function, and the blood glucose examination will also be affected after food is taken. The biochemical examination mainly includes liver function, kidney function, blood glucose, blood lipids and electrolytes. Of course, liver function mainly reflects the function of human liver, including transaminases, bilirubin, albumin and so on. Kidney function mainly includes creatinine, urea nitrogen and uric acid. Lipids include cholesterol, HDL, LDL and VLDL, and blood glucose is mainly fasting blood glucose.
