Comment:
  • Current card is Beckman Coulter Hemoccult® green/yellow card
  • The Diagnostic order should be placed if the patient has documented symptoms.
  • The Screening order should be placed if the testing is being preformed in the absence of documentation.
  • This is for stool specimens only. See GASTROCCULT® BODY FLUID for all other body fluids.
  • If using the Beckman Counter Hemoccult®  ICT blue card SEE: Occult Blood Fecal ICT Screen
Patient preparation:
  • Patients should be placed on the Special Diagnostic Diet starting at least 48 hours prior to and continuing through the test period.  This diet can increase the accuracy of the test results. 
  • Patients on unrestricted diets who test positive on one or more of the initial 3 slides is recommended to be retested after being placed on the special diet.See page 21 in the SPECIAL HELPS SECTION of the Lab Test Index for Hemoccult® (Occult Blood Feces) special diagnostic diet.
Specimen:
  • Fresh, unpreserved stool specimen
  • NOTE:  Fecal samples should not be collected if hematuria or obvious rectal bleeding, such as from hemorrhoids, is present.  Pre-menopausal women should not collect fecal samples during or in the 3 days following a menstrual period.
  • Collect a small fecal sample on one end of the applicator stick (may use tongue depressor)  Apply a small thin smear inside box A.  Use the other end of the applicator to obtain a second sample from a different area of the stool.  Apply a thin smear inside box B and close the cover. 
  • The test slide MUST be labeled with patient first and last name, date and time of collection.
