Description
A blood test for stomach wear could spare many people a camera exam, and one such test reads a pair of stomach-made proteins in the blood. Sun-Young Lee reviews how to read that test in a 2026 paper, since its meaning shifts with the kind and spread of stomach wear. Two very different diseases wear the stomach down: immune attack and a common germ infection.
In immune-driven wear, the first protein sinks hard and a stomach hormone climbs, marking deep wear of the stomach's main body. Germ-driven wear gives a softer, patchier signal. The test shines at spotting severe wear and grading risk, but it misses early wear too often. Lee notes that test brands use quite different cut-offs, so a number means little without knowing the kit. Paired with the hormone reading, the test helps rank cancer risk.
