Description of Test
The test is most often done at home.
When you are ready to have a bowel movement, you will set up the kit using the instructions. The kit should allow you to collect 3 samples. Some kits have a disposable container into which you can pass your bowel movement. Other kits give you tissue paper or plastic wrap that you can lay in the toilet to keep your stool from getting into the water.
You can also turn off the water valve to the toilet tank and flush the toilet a couple of times. This will empty most of the water out of the toilet bowl. When ready, pass the bowel movement into the bowl. Collect the sample, then turn the water back on.
Using thin wooden sticks from the kit, you will pick up a small sample of stool. You will then smear the sample onto a special card. If you do not have hemorrhoids, some doctors may allow you to smear the sample onto the card with stool from toilet paper. The card folds over to protect the stool sample.
You will mail or bring the cards to the clinic or lab. Make sure you have written your name on each card.
