Chapter 6: Lab Test, Clinical Procedure, Abbreviations Flashcards
amylase and lipase tests
tests for the levels of amylase and lipase enzymes in the blood

Tests for the presence of enzymes and bilirubin in blood
stool culture
test for microorganisms present in feces
stool guaiac test or hemoccult test
test to detect occult (hidden) blood in feces
lower gastrointestinal series
x-ray images of the colon and rectum obtained after injection of barium into the rectum
