Liver and kidney damage cannot be detected by routine blood tests, and liver function and pancreatic and renal function tests may be needed. Elevated aminotransferase in liver function suggests that liver function is impaired, while increased uric acid, creatinine and urea nitrogen in kidney function suggests that kidney function is impaired. For the liver and kidney function damage, it is necessary to find the cause of liver and kidney damage, which may be caused by drugs or other diseases. For medication causes, stop the medication in time, and carry out the treatment of liver and kidney preservation. For disease-induced causes, it is necessary to treat the primary disease, and after treating the primary disease, it is also necessary to protect the liver and kidneys. In the course of treatment, liver function and kidney function should be rechecked in time to observe the effect of treatment.
