An API representative reported that the formula is proprietary and has a human source for hemoglobin. For each testing period, proficiency testing programs sent two blinded samples to laboratories to test for the presence of hemoglobin in the sample.

It is disconcerting that negative samples tested positive. Further investigation to determine appropriate, reliable products for fecal occult blood testing is warranted. We called each testing program and determined the following seven programs conduct fecal occult blood testing: A quantitative immunochemical fecal occult blood test for colorectal neoplasia.

Samples spiked with human blood and control samples are sent to labs for testing, results are sent back to the proficiency testing program, and then summarized. The results serendipitously provide information about which tests are popular or more frequently used. After omitting duplicate names, 14 unique FITs remained for testing. hemsoure

The “Iowa Get Screened” colon cancer screening program. The purpose of this study was to summarize the accuracy of results of 8 individual FIT products across proficiency testing programs, in order to provide information about the validity of results obtained by various FIT products.


Evaluation of Fecal Immunochemical Tests for CRC Screening

Organized colorectal cancer screening in integrated health care systems. For the manual FITs, specificity ranged from Screening for familial colorectal cancer with a sensitive immunochemical fecal occult blood test: Analytical comparison of three quantitative immunochemical fecal occult blood tests for colorectal cancer screening.

However, some had low sensitivity and specificity and probably should not be used for population-based or other screening.

If an automated system is used, another issue to take into consideration is the cutoff point for hemoglobin detection. Lower positivity rates but still acceptable detection rates for early-stage colorectal cancers.

From those four lists, each test name was reviewed to determine if it was a guaiac test or an immunochemical test.

Higher fecal immunochemical test cutoff levels: Non-laboratory healthcare professionals need access to reliable and valid testing results to make informed decisions when selecting a fecal occult blood test product. Laboratories tested the samples using the fecal occult blood testing product used in their labs and reported results back as either positive hemoglobin present or negative no hemoglobin.

It is disturbing to find that some negative samples tested positive. Laboratories throughout the U.

CA Cancer J Clin. One would assume that the amount of hemoglobin henosure 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.

Please review our privacy policy. Performance characteristics and evaluation of an automated-developed and quantitative, immunochemical, fecal occult blood screening test. Purpose The purpose of hemoskre study was to summarize the accuracy of results of individual FIT products across pathology proficiency testing programs. However, additional information is still needed for deciding which product to use in a particular screening program. An MLE representative reported that their samples are a synthetic liquid and the positive samples are spiked with human hemoglobin.

Information from proficiency testing programs should be publically available. Each of the four proficiency testing programs was asked how their samples for fecal occult blood testing are prepared. Individual laboratories are provided with unidentified specimens for testing.
