The Occult Blood Test (OBT) is a diagnostic test used to detect the presence of hidden blood in a patient's stool sample. It is used to detect gastrointestinal bleeding, which can be caused by a variety of conditions, including ulcers, colorectal cancer, and inflammatory bowel disease. OBTs are typically performed in a laboratory setting, and the results are used to help diagnose and monitor the progression of these conditions. OBTs are typically performed using a chemical reaction that causes a color change in the presence of blood. The test is relatively inexpensive and non-invasive, making it a popular choice for diagnosing gastrointestinal bleeding. OBT market players include Siemens Healthineers, Abbott Laboratories, Roche Diagnostics, Becton Dickinson, and Sysmex Corporation. These companies offer a variety of OBT products, including test kits, reagents, and analyzers. Show Less Read more
