The general tumor quadruple test results are accurate. Tumor quadruple generally refers to the test results of tumor markers, and the test indexes represented by tumor quadruple tests are different according to the gender of men and women. Of course, there are some differences in the range of reference values in different testing institutions. But this result alone cannot determine whether it is cancer or not, it is just a reference. If the index is higher, it may represent malignant tumor, and further imaging examination as well as gastroscopy and other examinations are needed to confirm the cancer diagnosis should be determined according to the gold standard pathological examination. For men, the four tumor items may include AFP, carcinoembryonic antigen (CEA) as well as glycan antigen 19-9 (CA19-9) and prostate-specific antigen (PSA). For women, replacing PSA with CA125 is a relatively more specific indicator of ovarian cancer.
