The FOB Rapid Test Cassette (Feces) is a medical diagnostic device that quickly and accurately detects the presence of Human Occult Blood in fecal samples using a rapid chromatographic immunoassay technique. Various diseases, such as colon cancer, ulcers, polyps, colitis, diverticulitis, and fissures, can cause Fecal Occult Blood (FOB). Early stages of gastrointestinal problems may not show visible symptoms, only occult blood. Traditional guaiac-based methods lack sensitivity and specificity and require dietary restrictions before testing, making them less effective.
In contrast, the FOB Rapid Test Cassette (Feces) uses a double antibody sandwich assay to selectively detect low levels of Fecal Occult Blood at 50 ng/ml or higher, or 6 ug/g feces. The test's accuracy is not impacted by the patient's diet, making it a reliable diagnostic tool for healthcare professionals. By detecting Fecal Occult Blood in its early stages, the FOB Rapid Test Cassette (Feces) can aid in the prompt diagnosis and management of gastrointestinal disorders, leading to better patient outcomes.
Revised: The FOB Rapid Test Cassette (Feces) is a medical diagnostic device that utilizes a lateral flow immunoassay technique to qualitatively detect the presence of Human Occult Blood in fecal samples. The test cassette's membrane is pre-coated with anti-hemoglobin antibodies on the test line region, which react with particles coated with anti-hemoglobin antibodies in the specimen. The mixture then migrates upwards on the membrane chromatographically through capillary action to react with anti-hemoglobin antibodies on the membrane, resulting in the generation of a colored line.
The presence of a colored line in the test line region indicates a positive result for the presence of Human Occult Blood in the sample, while the absence of a colored line indicates a negative result. To serve as a procedural control, a colored line always appears in the control line region, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
The FOB Rapid Test Cassette (Feces) is a reliable and easy-to-use diagnostic tool for healthcare professionals to quickly and accurately detect the presence of Human Occult Blood in fecal samples. The test's procedural control ensures the accuracy of the results, making it a valuable tool for the diagnosis and management of gastrointestinal disorders.
