Morphology
Coombs + test
While the word 'test' signals a general examination or diagnostic procedure, 'Coombs' is an eponymic surname with no lexical meaning a B1 learner could use to infer the specific medical function. The precise purpose—detecting antibodies on red blood cells and screening for transfusion/prenatal issues—is specialized and not derivable from the constituents, so the expression's meaning is not predictable from its parts.
Etymology
Coombs test is named after Dr. Robin Coombs, who developed a way to see if tiny 'antibodies' are sticking to red blood cells. So the Coombs test today means a lab test that checks for those 'antibodies' on blood cells.
