Tumor abnormal protein TAP test detects dozens of abnormal glycoproteins such as methemoglobin, carcinoembryonic antigen, CA125, CA153, CA199 and other abnormal glycoproteins by highly aggregating them in the blood. It greatly amplifies the signal of tumor and overcomes the defect that conventional tumor markers can only detect a few abnormal glycoproteins, thus greatly improving the sensitivity of tumor detection. It can effectively screen out tumor-risk groups from a large number of asymptomatic medical checkups, and then combine with physical signs and medical history as well as other detection indexes to do further detailed examination on high-risk groups with positive TAP test for early detection of tumors. However, this test is not specific and has a certain false positive rate. Many patients with benign inflammation in the body may also have increased TAP. Therefore, patients with positive test should pay attention to review, and need to combine with clinical manifestations and other test results to make accurate diagnosis.
