Biohit has expanded its collection of diagnostic tests for gastro-intestinal diseases by launching its ColonView Hb and Hb/Hp quick tests. Developed for a faster detection and prevention of colorectal cancer, the ColonView quick tests are a simple and cost-effective solution. The testing will facilitate the diagnosis of patients with fecal occult blood (a major marker for colorectal cancer and pre-cancerous large adenomas). Also, the tests will help in identification of other diseases associated with bleeding.
