OC FIT-CHEK is performed using the OC-Auto Micro 80 or OC-Sensor Diana automated systems.
OC FIT-CHEK is used for detecting gastrointestinal bleeding associated with disorders such as colorectal cancer, polyps and colitis. More than 500 million tests have been performed worldwide using this method.*
The sample is collected and closed by the patient and never

reopened. The instrument measures the closed sample
collection devices. The laboratory technician never comes in
contact with the sample.
