multitarget stool DNA test
Advanced colorectal cancer screening test that analyzes stool samples for DNA mutations, methylation markers, and hemoglobin.
Full Definition
The multitarget stool DNA test is a noninvasive colorectal cancer screening method that combines analysis of multiple biomarkers including DNA mutations, DNA methylation patterns, and hemoglobin in a single stool sample. This test can detect both colorectal cancer and advanced precancerous lesions with higher sensitivity than traditional stool-based tests, though with reduced specificity. The test is recommended every three years for average-risk individuals and requires whole stool sample collection with specialized processing. Positive results require follow-up colonoscopy for definitive evaluation.
Usage
Usage note: Specify three-year testing interval; distinguish from annual stool-based tests.
