Morphology
The noun is a straightforward adjective+noun composition: 'gastric' (related to the stomach) modifies 'smear' (a specimen spread on a microscope slide), so the meaning 'a smear taken from the stomach for examination' is directly inferable. This follows a common medical naming pattern and has close equivalents in other languages, so a learner who knows both constituents can understand it.
Etymology
The noun gastric smear comes from gastric, meaning 'stomach', and smear, which means to 'spread' a thin sample on a glass slide. Doctors take a small sample from the stomach and spread it on a slide to look under a microscope for infection or disease, so the name describes the test.
