Routine blood test cannot check liver function and kidney function, only complete blood cell count, but blood biochemistry test can check liver function and kidney function. Routine blood test is mainly used to check the complete blood cell count, to clarify the number of core items such as red blood cells, white blood cells, neutrophils and platelets per liter of blood, so as to help doctors to diagnose or identify infections, anemia and other diseases, so routine blood test does not check liver function and kidney function. If you want to check liver function and kidney function, in addition to being able to do these two tests separately, you can also choose blood biochemistry, which contains a variety of tests, such as lipids, blood glucose, electrolytes and so on. Usually it is possible to do it together with the routine blood test. However, it is important to remember that there is no history of alcohol consumption before the test, so as not to affect the test results. To summarize, it is recommended that people who want to know about liver and kidney function should go to regular hospitals and cooperate with doctors to complete the relevant examinations, so as to facilitate the diagnosis of the doctor’s condition.
