To complete the test, you need to take tiny samples from two bowel motions using a test kit. These are analysed at a pathology laboratory, which checks the samples for blood. The process is quick, simple and hygienic.
The envelope contains everything you need to complete the test in your home - instructions, a flushable toilet liner, collection tube and stick, a sanitary zip lock bag and reply-paid envelope.
Watch the video below on how to do the test.
