New Quick Test for Fecal Occult Blood
22 Apr 2011Colorectal cancer is one of the most common cancers of the industrialized world, and it has a high mortality rate. Biohit is extending its range of diagnostic tests for gastrointestinal diseases with the ColonView quick test, which is intended to aid early diagnosis and prevention of colorectal cancer. ColonView testing can be used for simple and cost-effective identification of patients with fecal occult blood, which is a well-known marker for colorectal cancer and pre-cancerous large adenomas. ColonView testing can also give information on possible other disease of the gastrointestinal tract that is associated with bleeding.
ColonView Hb test detects human hemoglobin (Hb) from red blood cells, and ColonView Hb/Hp test detects hemoglobin/haptoglobin complex (Hb/Hp). They are immunological tests that specifically detect human fecal occult blood. For this reason, ColonView testing does not require a special diet on the days before or during sample collection. Patients can collect fecal samples at home on three consecutive days with the specific and convenient sample collection kit provided by the laboratory or the doctor, and forward the samples to the laboratory for single-step testing.
Risk groups for colorectal cancer include the elderly, and also relatives of colorectal cancer patients. Diagnosis of the cancer at an early stage significantly improves the prognosis. For this reason, screening programs for colorectal cancer are recommended or ongoing in many countries.
Screening for fecal occult blood has been found to improve early detection of colorectal cancer in many studies. The sensitive and specific ColonView tests are well suited for screening programs and for testing of patients in hospitals, doctors’ practices and occupational health centers for fecal occult blood. Patients who may benefit from this are those suffering from dyspepsia, and people over 50 years of age, in particular, as part of routine health checks.
The global market for quick tests intended for detection of fecal occult blood is already worth over EUR 500 million, of which most is still achieved by sales of tests that are not specific for human blood.

The detection of blood is based on highly sensitive immunochemical detection of hemoglobin or hemoglobin/haptoglobin complex. The principal use of the Biohit ColonView Hb and Hb/Hp tests is to screen for lower gastrointestinal (GI) pathologies, such as colorectal cancers and large adenomas that bleed. The Biohit ColonView tests are specially designed to detect human hemoglobin and hemoglobin/haptoglobin complex in stool samples using immunochemical method, with improved specificity for the detection of lower GI disorders, including colorectal cancers and adenomas. ColonView Hb test is an ideal tool for colorectal cancer screening. Combination of the ColonView Hb test with the ColonView Hb/Hp test improves the detection of also large adenomatous polyps, which may develop into colorectal cancer. To ensure the best detection of bleeding in the colorectal tract, ColonView Hb test should be used in combination wíth ColonView Hb/Hp test to detect hemoglobin/haptoglobin complexes. ColonView Hb and Hb/Hp tests are provided with easy-to-use patient Sample Collection Kits that include all that is needed for convenient home sample collection, without the need to touch fecal samples. The same sample can be used for both Hb and Hb/Hp testing. ColonView Hb and Hb/Hp tests are simple, one-step lateral flow tests that give a result in 15 to 25 minutes. Please note: ColonView lateral flow tests are for research use only in the United States
