Description of intervention(s) / exposure
The study is an open study designed to determine the clinical specificity of the bowel cancer screening tests QuickVue(R) faecal immunochemical test (FIT) and to compare this to Hemoccult II(R) Sensa(R).
A new immunochemical, faecal occult blood test (FOBT) QuickVue(R)FIT has recently been developed, that incorporates features that may result in improved population participation.
These features relate to sampling process itself where a specimen is taken by inserting into the stool a small grooved probe instead of the more traditional spatula sampling; therefore the QuickVue(R) FIT device uses a stool sampling procedure where a small probe is inserted into the stool surface at multiple points and then transferred to a plastic container containing a stabilization solution which is then sealed. The test is then activated and a stable test result is generated which is concealed from the participant.

The Hemoccult II(R) Sensa(R) device is a guaiac (chemical) test, which employs a direct stick-based faecal sampling method to collect a sample from a stool captured by defaecating onto a stool collection sheet held above toilet bowel water. The faecal sample is then smeared onto a collection card by the patient using a small wooden spatula, allowed to dry and sent to the developing laboratory using postal system approved packaging.

Therefore one significant difference between these devices is that the Hemoccult II(R) Sensa(R) uses a stick-based stool sampling method while the QuickVue(R) FIT uses a probe sampling method. While there are other inherent differences between the sampling methodologies used in the QuickVue(R) FIT and the Hemoccult II(R) Sensa(R) test devices, a study based on a direct, per-stool comparison is practical.

To complete both devices a total period of approximately 6 days, depending on bowel habit, is expected.

This study commenced enrolment 7 July 2009. Enrolment is expected to be completed in June/July 2010.

These tests are undertaken simultaneously using the same stool sample; i.e. the participant will use both the FOBT QuickVue(R) FIT and the Hemoccult II(R) Sensa(R) device on the same sample of stool on three different occasions.
All participants use the Hemoccult II(R) Sensa(R) device first followed by the QuickVue(R) FIT
This is a single procedure. Participants only receive the tests on one occasion.

Comparator / control treatment
The Hemoccult II(R) Sensa(R) device, a guaiac (chemical) test.
Hemoccult II(R) Sensa(R) is a development of Hemoccult II(R), which was the Faecal Occult Blood Test (FOBT) used in the randomised controlled trials that showed that screening reduced mortality from Colorectal Cancer (CRC).

Outcomes
Primary outcome [1] 258421 0
The primary aim of this study is to compare the clinical specificity (proportion of positive tests in a population known not to have the condition under test) of the faecal immunochemical test (FIT) QuickVue"Registered Trade Mark (R)"
relative to an approved chemical device Hemoccult II(R) Sensa(R)
The device end point and result for each patient will be defined as per the device manufacture?s instructions. In the case of the Hemoccult II(R) Sensa(R) device, a positive result recorded for one or more of the six individual samples, corresponding to three separate bowel movements, will yield a positive result for that patient. In the case of the QuickVue(R) FIT test, the positivity or negativity for that patient will be interpreted in similar fashion.
Timepoint [1] 258421 0
Specificity is assessed at completion of both tests
Secondary outcome [1] 264195 0
To compare the clinical specificity of QuickVue(R) FIT using test devices with differing sensitivities i.e. cut-offs set at 50and 100 ngHb/ml).
Timepoint [1] 264195 0
Specificity is assessed at completion of both tests
Secondary outcome [2] 264196 0
To compare the clinical specificity of each test on a one, two or three stool basis.
Timepoint [2] 264196 0
Specificity is assessed at completion of both tests

Summary
Brief summary
A study comparing two different faecal occult blood testing kits (FOBT). These are tests for detecting early signs of bowel cancer.
Patients will be invited who have had a diagnosis of a normal bowel after colonoscopy within the last eighteen months
The aim of this study is to determine the accuracy of a new FOBT kit (QuickVue(R) FIT(R)) compared to a proven FOBT kit (Hemoccult II(R) Sensa(R) for detecting the presence of hidden blood in the stool (occult blood). Occult blood in stool is an indication of a number of relatively mild bowel diseases as well a symptom of bowel cancer and bowel polyps. We need to be sure that the QuickVue test does not detect extremely low levels of blood loss which occurs in normal healthy people, to ensure that the test does not give false positive results.
