This source discusses the decision whether in ICD10, faecal occult blood should be coded to『R19.5 – Other faecal abnormalities』or "K92.1 - Melaena", and concludes that because "ICD10 can’t measure the quantity of blood, a diagnosis of faecal occult blood should be coded to K92.1 - Melaena". --Arcadian 14:19, 23 December 2005 (UTC)[reply]
I tried to trim some of the excessive marketing hype. The article has been infected by too many confusing trademark terms. It needs to get cleaned up and organized, by someone who actually understands the trademarks.-69.87.203.221 00:56, 28 June 2007 (UTC)[reply]

Colorectal cancer screening clinical practice guideline
MAJOR RECOMMENDATIONS
Definitions of the levels of evidence (evidence-based A-D, I and consensus-based) are provided at the end of the "Major Recommendations" field.
Recommendation 1*: Factors Associated with an Increased Risk of Colorectal Cancer in the General Population
...
Recommendation 2: Effectiveness of Colorectal Cancer Screening Tests
1. Colorectal cancer screening is strongly recommended for all asymptomatic, average-risk adults. (Evidence-based: A) 2. Any of the following tests are acceptable for colorectal cancer screening in asymptomatic, average-risk adults:*
3. The following additional screening tests are either less-preferred options or not recommended for screening. However, an adult who has had one of these tests is considered screened. Follow-up screening using a preferred option is recommended.
Note: For fecal blood tests, inform patients of the potential risks associated with false-positive test and false-negative test results, as well as the need for prompt follow-up of a positive test result. For flexible sigmoidoscopy, inform patients that the test has a small risk of complications and is not a complete examination of the entire colon.
*There is insufficient evidence to choose one screening test over another.
Recommendation 3: Frequency of Colorectal Cancer Screening
1. The following intervals for colorectal cancer screening in asymptomatic, average-risk adults are recommended*:
2. The following additional screening tests are either less-preferred options or not recommended for screening. However, if these tests are performed, then the recommended intervals are as indicated below. Follow-up screening using a preferred option is recommended.
Recommendation 4: Age to Begin and End Colorectal Cancer Screening
In the absence of sufficient evidence, the following ages at which to begin and end colorectal cancer screening in asymptomatic average-risk adults are recommended:
1. Initiation of screening is recommended at age 50. (Consensus-based) 2. Discontinuation of screening is generally recommended at age 75, provided that there is a history of routine screening. For those with no history of routine screening, discontinuation is recommended at age 80. The decision to discontinue screening should be based on physician judgment, patient preference, the increased risk of complications in older adults, and existing comorbidities.

After recently reviewing the recommendations and editing the article in accordance with them, as a new and inexperienced Wiki person I then stumbled on this talk item, and I realise I should have been here first. That said, I agree that the guidelines need to be discussed and referenced, and I have initiated that, but I presently disagree that the guidelines generally mandate sigmoidoscopy, despite the outlier advocacy of ACG. My personal preference in favor of the ACG position, for a variety of reasons, is not rigorously supported on reviewing the literature, and is not appropriate for an encyclopedic text.--FeatherPluma (talk) 18:18, 29 October 2010 (UTC)[reply]

Graphic is traditional gFOBT, which is no longer recommended. Replace with graphic of currently-recommended test. — Preceding unsigned comment added by Ocdncntx (talk • contribs) 18:19, 20 September 2011 (UTC)[reply]
It would be very useful to add a new section to the article about the signs and symptoms that warrant tests for fecal occult blood. (I was actually looking for that information when I checked this article.) 84.0.42.178 (talk) 09:51, 24 January 2013 (UTC)[reply]
This article refers several times to "guidelines", "best practices recommendation" and the like, with no reference to what places use these guidelines. For example, the guaiac test is still the test sent out for routine screening in the UK. If the guidelines mentioned are the ones used in America, fair enough, but say so!
The Fecal DNA Test has little relevance to this page, as (according to its name, and the description here) it does not test for faecal occult blood. This page is about faecal occult blood testing, not colorectal cancer testing, which I'm sure is covered elsewhere. Browneyedgirl13 (talk) 10:14, 13 September 2013 (UTC)[reply]

Wikipedia needs a separate article on
Colorectal cancer screening
The new article should replace and subsume this current article on no-longer-recommended fecal occult blood testing, which has not been updated to reflact current best practices for screening, as show in peer-reviewed studies indicating that fecal occult blood testing misses too many cancers.
Where is the FIT-iFOBT article to correspond to the gFOBT article?-71.174.175.150 (talk) 19:44, 14 November 2014 (UTC)[reply]
This is a tricky article to get right! It is ostensibly about Fecal Occult Blood tests, and yet in general the purpose of such tests, and the goals of most readers, has to do with colon cancer. On the one hand, the proper measure of an FOB test should be whether it reliably detects fecal blood, at various levels. And that should be the proper context for judging False Neg and False Pos rates, narrowly defined. But I think in the real world these tests are judged by colonoscopies and colon cancer correlations. Somehow the article should separate out these two different perspectives on the test accuracies?-71.174.175.150 (talk) 22:03, 14 November 2014 (UTC)[reply]
The FIT test looks at globulin instead of heme, and so the FIT test can better distinguish upper from lower GI bleeding, making it a more-specific test. Thus the FIT test might be a follow-up if an initial less-specific test revealed blood in the stool.
