Hemosure's One Step Immunological Fecal Occult Blood Test (FIT) for colorectal cancer screening selectively identifies human hemoglobin in test samples with a high degree of sensitivity. The objective is to detect and diagnose diseases that result in lower gastrointestinal (GI) bleeding, such as colorectal cancer. This allows for cancer detection at an early stage, thus reducing mortality. Positive results for minimal levels of hemoglobin can be detected in as early as 5 minutes. The test does not require any drug or diet restrictions, yet maintains high sensitivity and specificity.
