This editorial examines whether the multitarget stool DNA (mt-sDNA) test is truly more effective than fecal immunochemical tests (FIT) for colorectal cancer screening or just more complex and costly. While lowering the FIT threshold can improve sensitivity, mt-sDNA still outperforms FIT even at comparable specificity levels. Differences in study methods—such as comparing separate cohorts or using different FIT brands—may explain conflicting results. The authors emphasize the need for direct, same-sample comparisons to accurately assess test performance.
