Meltzer-Lyon test

Melt·zer-Ly·on test

(melt'zĕr lī'on),
a test used in diagnosis of gallbladder conditions: 25 mL of a 25% solution of magnesium sulfate is delivered into the region of the sphincter of Oddi through a duodenal tube, causing contraction of the gallbladder, relaxation of the sphincter, and the expulsion of bile from the common duct and gallbladder; bile from the common duct is relatively pale and is expelled first, that from the gallbladder follows; samples aspirated from the tube are examined for pus cells, pigment granules, epithelial cells, cholesterol, and the like.

Meltzer-Lyon test

An obsolete term for the use of MgSO4—which causes a contraction of the gallbladder and relaxation of the sphincter of Oddi—to retrieve intact bile for chemical or cytological assessment.
