Chap 3 - Gastrointestinal Diagnostic Procedures Flashcards
Blood test for the enzyme alkaline phosphatase that’s found in both liver cells and bone cells. Elevated blood levels suggest the presence of liver disease or bone cancer.
Alkaline phosphatase
Blood test for albumin, the major protein molecule in the blood produced by the liver. Liver disease causes albumin levels to be low.
Albumin
Blood test for the enzyme Alanine Transaminase and Aspartate Transaminase. These enzymes are mainly found in the liver. Formerly known as SGPT and SGOT
ALT and AST
Blood test for unconjugated, conjugated, and total bilirubin levels. These levels are abnormal when there’s liver disease or gallstones.
Bilirubin
Also known as direct bilirubin because it reacts directly with the reagent used to perform the laboratory test.
Conjugated bilirubin
Also known as Indirect bilirubin because it only reacts when another substance is added to the reagent.
Indirect bilirubin
Blood test for the enzyme gamma-glutamyl transpeptidase. Elevated blood levels mean damaged liver cells released this enzyme into the blood. Also known as GGTP
GGT
Panel of individual blood tests performed at the same time to give a comprehensive picture of liver function. Includes albumin, bilirubin, ALT, AST, GGT, and prothrombin time.
Liver Function Tests (LFTs)
Rapid screening test to detect the presence of the bacterium Helicobacter pylori.
Stands for Campylobacter-like organism
CLO test
Diagnostic test to detect occult blood in the feces. A sample of feces is placed on paper and mixed with the chemical reagent guaiac.
Fecal Occult Blood Test
Diagnostic test to determine the amount of hydrochloric acid in the stomach. An NG tube is inserted and gastric juice sample collected.
Gastric analysis
Diagnostic test to determine if there is a parasitic infection of the gastrointestinal tract.
Ova and Parasites (O&P)
Diagnostic test that determines which bacterium is causing an intestinal infection and which antibiotic drugs it is sensitive to.
Stool Culture and Sensitivity (C&S)
Radiologic procedure that uses a liquid radio plaque contrast dye (barium) introduced through the rectum. Barium outlines and coats the walls of the rectum and colon and an x-Ray is taken. Used to identify polyps, diverticula, ulcerative colitis, and colon cancer.
Barium enema
Radiologic procedure that uses a contrast die yo outline the bile ducts. And X-ray is taken to identify stones in the gallbladder and biliary ducts or thickening of the gallbladder wall.
Cholangiography
