The urobilinogen is then allowed to react with Ehriich's reagenttoforma red color which can be measured `spectrophotometrically. 03590 ed SET WOIO3L OAM WPIED 65, PT NUT Unit Code 8308 1/14/99 2:56PM - oo. UROBILINOGEN, 48-HOUR, FECES tinical Information CLINICAL INFORMATION: - Urobilinogen consistsofthe colorless end productsofbilirubin metabolism which are oxidized by intestinal microorganisms to brown pigments (stercabilin). - Normally, fecal urobilinogen approximates the total excretion of bile pigments (the breakdown productsof heme). USEFUL FOR - Diagnosisofdisorders involving hemolysis and hepatic obstructive conditions INTERPRETATION - Increased destructionofred blood cells, such as in hemolytic anemia, increases the amount of urobilinogen excreted. - Liver diseases in general lessen the flow of bilirubin to the intestine and thus decrease fecal excretionof uroblinogen. - Complete obstruction of the bile duct reduces the urobliinogen of the feces to verylow levels. Clay-colored feces in obstructive Jaundice resus from the exclusion of bile pigments from the intestine. -Oral administration of broad-spectrum antlbiotics diminishes conversion of the bilirubin to urobilinogen in the Intestines. CAUTIONS - Information about oral broad spectrum antibiotics taken recently by the patient must be accurate. Oral broad spectrum antibiotics decrease urabiinogen measurements by diminishing bacterial conversion of bilirubin to urobilinogen in the feces, leading to faisely low values. IMMEDIATE fixationofspecimen by the prescribed preservative (sodium carbonate/petroleum ether) in an opaque container is essential, since urobilinogen is light sensitive. Poor fixation gives a falsely low reading.
