How long does the liver puncture needle test produce results?

Liver biopsy is an invasive examination method. It is the gold standard for the diagnosis of liver disease by obtaining tissues from liver lesions for pathological examination. The detection accuracy rate can reach 80%-90%, and liver biopsy is generally 5-7 days before the final detection result can be obtained. The time required for benign lesions is relatively short, 3-5 days. Malignant tumors may take a long time, and further immunohistochemical examinations may be required to make the final confirmation. Although the accuracy of liver biopsy is relatively high, the final test results may also be false negatives. The test results, symptoms, signs, and other auxiliary examinations need to be comprehensively judged. For liver biopsy as benign, but clinically highly suspected of malignant tumors, more aggressive surgical treatment can also be adopted.
