How does the test work?

The-Test® is used for the screening of colorectal cancer by detecting so-called occult (hidden blood not visible to the naked eye) in the stool. Since the test can only differentiate between the presence and absence of blood in the stool, the test cannot be used to determine the cause of the blood admixture in the stool. A positive test therefore does not necessarily indicate a disease and must first be examined more closely by further diagnostic means.

How does the evaluation work?

How the exact evaluation of the Test® works depends on the type of test set. Normally the test is performed at the doctor’s office, who can either read the result himself or have the sample examined in the laboratory. If you want to do the-Test® privately, it is best to take the exact evaluation from the package insert.

Normally there is a surface with fields for a positive and a negative test. Depending on whether the test set finds occult blood in the stool or not, this leads to a marking of the field “positive” (=blood in stool) or “negative” (=no blood in stool).
