Rapid self-test for detection of blood in feces (associated with colon cancer)
Hemoglobin, a vital protein in red blood cells, is crucial for oxygen transport throughout the body. In fecal blood testing, hemoglobin gains significance as bleeding in the gastrointestinal tract can lead to its presence in the stool. Fecal blood, a potential indicator of various gastrointestinal disorders, can be challenging to detect due to silent symptoms. Visual examination alone may fall short, making the identification of blood in feces essential for revealing underlying gastrointestinal issues. Regular screening for fecal occult blood is recommended, especially from age 45, for early detection.
Poly-Check, an immunological rapid test specific for detecting hemoglobin in feces, distinguishes itself by eliminating the need for dietary restrictions common in guaiac tests. Acknowledging that polyps may intermittently bleed, Poly-Check advocates a three-day consecutive stool sampling approach, increasing the likelihood of detecting intermittent bleedings and providing more reliable information for patient safety.

How to use
Sample Collection (First, Second, and Third Day):
- Wash hands and collect faeces on a separate paper strip each day.
- Dip the vial tip into the faeces, avoiding excess for accurate results.
- Securely cap the vial, shake to suspend the sample, and store it in the refrigerator.
- Dispose of the paper strip in the toilet.
Test Realization (After 3 Days Collection Period):
- Tear open the pouch, remove the device, and let the vial reach room temperature.

Summery
The test is positiveTwo coloured lines appear in the windowunder the marks T (Test) and C (Control). The intensity of theline T may be clearer than the intensity of the line C. Thisresult means that blood is present in the faeces and that youshould consult a doctor.
Test is negativeOnly one coloured line appears underthe mark C (Control). This result means that no blood isdetectable in the faeces sample.
Invalid resultNo line appears under the mark C. Inthis case, it is not possible to interpret the test, which mustbe considered as non valid. It is recommended to repeatthe test with a new Poly-Check® test and a fresh sample offaeces.
Questions and answers
How does Poly-Check® work?
Gastro-intestinal lesions are often bleeding. The blood can be detected specifically by Poly-Check® in the faeces when concentration is higher than 10 ng/mL. The presence of blood can be explained by several causes: ulcers, haemorrhoids, colorectal cancer. The probability for intermittent bleeding to be detected is increased by the procedure of sample collection over 3 running days.
Poly-Check® test uses a pair of antibodies detecting specifically human haemoglobin by producing a coloured test line under the T mark of the cassette. A control line capturing the reagent excess appears as a coloured line under the C mark of the cassette. In case both lines appear, the test indicates that the level of haemoglobin is higher than normal (> 10 ng/mL determined against purified human haemoglobin material).
This procedure allows a more accurate test result for the patient especially for early stages of diseases and, therefore, greater probability to cure them.
When the test should be performed?
Poly-Check® test can be performed at any time of the day when having a bowelmovement.
Can the result be incorrect?
The results are accurate as far as the instructions are carefully respected.Nevertheless, the result can be falsified if Poly-Check® test gets wet before testperforming or stool collecting steps are not correctly performed or if the sampleis contaminated with blood from other origins than faeces (cuts, haemorrhoids,menses etc…) or if an incorrect number of drops is dispensed in the sample well.
How to interpret the test if the colour and the intensity of the lines are different?
The colour and intensity of the lines have no importance for resultinterpretation. The lines should only be homogenous and full.
What is the line that appears under the mark C (Control) for?
When this line appears, it only means that the test performed correctly and that the test result is valid, but it does not play any role in result interpretation.
If I read the result after 15 minutes, will the result be reliable?
No. The test should be read after 10 minutes and before 15 minutes after havingadded the extract. The results are reliable up to 15 minutes.
What do I have to do if the result is positive?
If the result is positive, it means that blood has been detected in the stoolsample and that you should consult a doctor to show the test results. Then, thedoctor will decide what you have to do.
What do I have to do if the result is negative?
If the result is negative, it means that the test could not detect blood in stoolsample. Meanwhile for the patients aged of 45 years and over or havingrelatives suffering from colorectal cancer, it is recommended to perform a testevery year.
What is the accuracy of Poly-Check®?
The Poly-Check® test is accurate and has been used for more than 10 years by professionals in the field. Evaluation reports show an overall agreement of at least 93% ([86.78 – 97.17*]) with different reference methods. Although this test is reliable, false positive or false negative results could be obtained.
