There are many clinical liver and kidney tests, some of which can be performed for both liver and kidney tests, but some of which still need to be examined by special programs. At present, the most basic tests for liver and kidney are liver function and kidney function, liver ultrasound and kidney ultrasound. Both of these can be done through venous blood sampling and ultrasound at the same time, which is also the most common way of checking in the clinic and one of the items in the physical examination. These two tests can initially determine whether there are any lesions in the liver and kidneys, and if there are abnormalities, further testing options can be selected based on the results of the tests. The examination of liver also includes Hepatitis B V, Hepatitis B Virus DNA Quantification, Liver Fiber IV, and Liver Hardness Value Test. The examination of kidney also includes urine routine, KUB flat film, 24-hour urine protein measurement, pyelogram, and fractional renal function. For occupying lesions such as liver and kidney, sometimes enhanced CT, MRI and puncture biopsy can be used for further clarification.
