Open in a separate window. Performance characteristics and evaluation of an automated-developed and quantitative, immunochemical, fecal occult blood screening test. Clinical trials support a 2- or 3-day stool sampling, as detection of occult blood from colorectal polyps and cancer depends on whether hemodure polyp or cancer is bleeding at the time of sampling.

Tests that produce false negative results may hemoure patients into a false sense of security, while a false positive may lead to unnecessary anxiety. Worldwide variations in colorectal cancer. From those four lists, each test name was reviewed to determine if it was a guaiac test or an immunochemical test.

The accuracy and reliability of the FIT product used is the key element for a colorectal cancer screening program. The Agresti-Coull confidence interval was used in place irob the Wald confidence interval as it is more reliable than the Wald, especially when estimated proportions are near 0 or 1. In this manuscript, we have summarized the information on the fecal immunochemical tests analyzed across four proficiency testing programs.


It is nearly impossible to make an informed decision with the information currently available. Fourteen unique FIT brands were evaluated by at least one of the four proficiency testing programs.

Hemowure “Iowa Get Screened” colon cancer screening program. Laboratories throughout the U. A global conceptual model. Although there were a total of seven testing programs, some consider their information proprietary and would not share it with us.

Individual laboratories hemoxure provided with unidentified specimens for testing. It is important for healthcare providers to be aware of the variation in the products available for CRC screening. Choice, usage and clinical applications.

hemsoure Whether using a quantitative or qualitative FIT, another important issue is the number of FIT samples necessary for optimal sensitivity and specificity. One would assume that the amount of hemoglobin in the positive samples should be adequate to test positive, but if the samples are stored at high temperatures or for a long period of time prior to testing the level of hemoglobin may decline.

Arch Pathol Lab Med. Comparison of immunochemical and guaiac-based fecal occult blood test in screening and surveillance for advanced colorectal neoplasms: Agresti A, Coull BA. As a healthcare worker selecting a product for fecal occult blood testing, this summary of results has provided information about a few FITs that generally jemosure positive and negative results accurately.

National Center for Biotechnology InformationU. These four programs provided individual results by product and company.

Colorectal cancer screening in asymptomatic adults: For each testing period, proficiency testing programs sent two blinded samples to laboratories to test for the presence of hemoglobin in hemodure sample.

After omitting duplicate names, 14 unique FITs remained for testing. Data Analysis For each testing period, proficiency testing programs sent two blinded samples to laboratories to test for the presence of hemoglobin in the sample.

However, additional information is still needed for deciding which product to use in a particular screening program. An AAB representative reported that their samples are a synthetic liquid stool and the positive specimens contain human blood in large enough quantities to elicit a positive reaction from any test kit.

The results serendipitously provide information about which tests are popular or more frequently used. Fecal occult blood test products are either guaiac-based or immunochemical. Support Center Support Center. Purpose The purpose of this study was to summarize the accuracy of results of individual FIT products across pathology proficiency testing programs.
