Slide3Fecal Occult Blood Testing: General Overview of Testing
As with any fecal occult blood test, results are not to be considered conclusive evidence for the presence or absence of any gastrointestinal pathology. The test is not a substitute for other diagnostic procedures such as endoscopy or colonoscopy, barium enema or other studies.The fecal occult blood test will be considered a screening test at WellOne. Positive results must be followed with diagnostic procedures to confirm and when indicated, negative results should be followed with recommended testing. Since bleeding from gastrointestinal lesions may be intermittent, fecal samples for testing should be collected from three consecutive bowel movements or three bowel movements closely spaced in time. To further increase the probability of detecting occult blood, separate samples should be taken from two different sections of each fecal specimen. Foods which contain peroxides may leave residues in the feces that may interfere with the test. The expected/normal result is a sample that is negative for fecal occult blood.This test should not be performed for screening for colon cancer but rather used as a diagnostic aid when GI bleeding is suspected.

Slide6Fecal Occult Blood Testing: Storage and Stability
Test slides:Store slides at room temperature (15-30ºC), protected from light, heat, and UV radiationSlides are stable until expiration date unless general integrity is interrupted.Developer Solution:Store developer at room temperature (15-30ºC)If properly stored, developer will remain stable until expiration date on bottle.

Slide12Fecal Occult Blood Testing: Procedural Steps
Open perforated cover on back of slide.Apply 2 drops of developer solution to each smear in specimen test area and read at 30-60 seconds.A positive result is indicated by the appearance of any blue color in the testing window. A lack of blue color indicates a negative result.

Slide19Fecal Occult Blood Testing: Procedural Steps
Develop the performance control for each slide (only after specimen tests have been completed and interpreted) by applying 1 drop of developer solution to the performance Control line.A blue color should appear within 30 seconds (indicating a valid test slide).Remove and dispose of gloves in regular trash; perform hand hygiene.Document results in the patient record (verbally alert provider of any positive results) and mark on the encounter form.

Slide20Fecal Occult Blood Testing: More On Control Testing
The internal control must be performed with each test done by applying 1 drop of developer solution to the performance control line only after the interpretation of the actual test results. A blue color should appear within 30 seconds. A positive control test lets us know that both the slide and solution are likely to give accurate results. A negative control tells us that there is a problem with either the test slide or solution and the test results are not valid. If the control is negative, disregard the testing results and perform control testing on another slide from the same lot. If the control is positive, repeat testing using another slide and interpret test and control results accordingly. If the control remains negative, immediately notify the COO or designee. Action to taken includes the determination of the source of the problem (ie. developer verses test slides). Use a different developer solution from same lot if possible on same lot of test slides-if control is now positive, discard the original developer solution bottle. If control remains negative, test the same lot of test slides using a developer solution from a different lot. If control is now positive, segregate and return all developer solution bottles of this lot number. If control remains negative, run the control on a test slide from a different lot of stool cards. If control is now positive, segregate and return to manufacturer all test slides of the affected lot number.
