When the nurse performs a hemoccult test on a stool specimen, blood in the stool will change the color on the test paper to blue.
An at-home test called the hemoccult is performed to find hidden blood in your stool. Blood in your stool that you can't see in the toilet or on the toilet paper after you use the bathroom is known as occult blood.
The hemoccult test is primarily utilized as a colorectal cancer diagnostic technique. Its premise is that big polyps in your colon are delicate and susceptible to injury by stools. The polyps flow into the intestine as a result of this injury. The blood is then eliminated with the stool, but it is frequently little and cannot be seen with the unaided eye. Stools that are visibly bloody may indicate other disorders.
