Occult Blood Testing

Customer FAQ

 

Propper Manufacturing knows that fecal occult blood testing is a sensitive subject for most patients. Seracult® and Seracult® Plus were designed to be performed where the patient feels the most comfortable in doctor’s offices, hospitals, clinics, laboratories, or in the comfort of a patient’s home. Below are frequently asked questions patients commonly ask before undergoing occult blood testing.

Occult Blood Testing FAQ

Q: What is the sensitivity level of Seracult®?  
A: Sensitivity for Seracult® is 0.38 mg of hemoglobin per 100ml of water.

Q: What is the sensitivity level of Seracult® Plus?  
A: Sensitivity for Seracult® Plus is 0.32 mg of hemoglobin per 100 ml of water.

Q: What is the difference between Seracult® and Seracult® Plus? 
A: Seracult® Plus is a more sensitive test than Seracult® and is intended for patients deemed at an increased risk of colorectal cancer.

Q: Who should be tested for Colorectal Cancer?  
A: The American Cancer Society recommends annual colorectal cancer screening for persons 45 and older. Clinicians may also use this test to detect occult blood due to other gastrointestinal bleeding.

Q: Who should be tested with Seracult® Plus?  
A: Any person that has higher risk factors due to medical or family history.

Q: Is Seracult® and Seracult® Plus CLIA waved?
A: Yes, both tests are CLIA waived.

Q: What CPT codes can be used?  

  • Screening CPT: 82270 Blood, occult, by peroxidase activity (e.g., guaiac), qualitative; feces, consecutive collected specimens with single determination, for colorectal neoplasm screening [i.e., the patient was provided three cards or single triple card for consecutive collection]
  • Diagnostic CPT: 82272 Blood, occult, by peroxidase activity (e.g., guaiac), qualitative, feces, 1-3 simultaneous determinations, performed for other than colorectal neoplasm screening.

Q: How long can the sample remain on the collection card before test development?  
A: The sample is stable for 28 days under normal conditions.

Q: Can different lot numbers of developers and slides be used together?  
A: Yes, as long as the expiration dates are valid and you are not combining Seracult and Seracult Plus products.

Q: Is the collection tissue septic safe?  
A: Yes, the collection tissue is septic-safe.

Q: To which address do I send the test when all samples have been applied?  
A: The test should be mailed or brought back to the doctor’s office, screening program, or hospital where you obtained the test. Propper does not process test samples.

Q: What storage conditions are required for the developer?  
A: The developer should be stored in a dark place, away from heat and light.

Q: How is a positive result interpreted?  
A: Any indication of a blue color in the test area, assuming you have a positive blue color in the control line. If using a triple slide, a blue color in any test area is a positive result.

Q: If the patient applies the sample to the reverse side of the slide, is the test still valid? 
A: No, the patient must be retested.

Q: Does Seracult® or Seracult® Plus contain latex or DEHP?  
A: No, our Seracult® products are both latex-free & DEHP-free.

Q: Does Propper consult patients on test results?  
A: No. Propper’s scientists cannot consult patients due to HIPAA regulations.

Q: Are there any advantages of guaiac FOBT testing over immunoassay FOBT (iFOBT or FIT) tests?

  • Guaiac testing has been in practice for over three decades and has many clinical trials to substantiate its claims.
  • Most iFOBT tests use buffers to dissolve samples. Typically, a reaction starts after adding the sample to the buffer, and sensitivity decreases, especially at room temperature.
  • Delivery delays & temperature fluctuations can result in false negatives.
  • iFOBT is less sensitive to bleeding in the upper GI tract.

Q: Any advantages of using Seracult® and Seracult® Plus over competitors? 

  • Seracult® and Seracult® Plus has a more visible and intense blue color as a positive indicator.
  • Seracult® has a patented enhanced formula for higher sensitivity. Only one other competitor (Beckman-Coulter) offers a more sensitive test.
  • Seracult® and Seracult® Plus samples are mailed in a USPS-approved envelope.

Q: Do healthy people lose blood from the gastrointestinal tract?
A: Yes, the average normal blood loss ranges from .5 ml to 1.5 ml per day. Seracult® and Seracult® Plus sensitivities are above that cut-off level, minimizing false positives.
