Immunochemical FOBTs Moderately Sensitive and Highly Specific for Colorectal Cancer [POEMs]

Immunochemical FOBTs, such as OC-Micro, OC-Sensor, or OC-Light, are moderately sensitive (73% to 89%) and highly specific (92% to 95%) for identifying colorectal cancer. In comparison, Hemoccult Sensa has a lower sensitivity (64% to 80%) and specificity (87% to 90%). Immunochemical FOBTs also have the advantage of requiring only one sample.
