There are many types of tests for liver-related diseases, which can be divided into two categories according to whether the tests are traumatic to the patient: the first category is noninvasive tests, such as the familiar blood sampling for liver function, hepatitis A, B, C, D, and E virus testing, liver ultrasound, CT, and MRI; the second category is based on liver biopsy histology, which is commonly known as invasive tests represented by liver puncture biopsy, in which a small portion of the liver is removed from the body for histological or cytological examination. The second category is liver biopsy, which is commonly known as invasive testing represented by liver puncture biopsy, where a small portion of the liver is removed from the body for histology or cytology.
The applications of liver aspiration biopsy are broadly diagnostic and evaluative. One is for liver diseases that require diagnosis: for example, different staging of acute and chronic hepatitis, clarification of whether a neoplastic mass is benign or malignant, and abnormal liver function that cannot be detected as a cause by conventional examination means. Secondly, it is used to assess the treatment effect and prognosis, such as different staging of malignant tumors, different treatment effect and different prognosis. The liver puncture biopsy is an invasive test, and patients are advised to have this test evaluated by a specialist to see if it can be performed.
