Stool DNA Test

http://www.medicalook.com

STOOL DNA TEST DEFINITION

A stool DNA test is another method to screen for colon cancer. It was developed to discern recognizable DNA changes (DNA markers) in cells that are constantly shed from the colon's lining through feces. These markers are linked with the surfaces of precancerous polyp and cancerous tumor cells.

STOOL DNA TEST PURPOSE

It's used to screen for precancerous polyps and, as already mentioned, colon cancer. The colon's lining is always shedding cells. As such, if there are polyps and tumors present, their shed cells should be present in the stool itself as DNA markers. The test can detect several of these markers and show whether or not colon cancer is present.

STOOL DNA TEST RISKS

There are no risks associated with a stool DNA test. Just bring a sample of your stool for testing, and you're good to go. You don't have any risks for complications or side effects after the test since it's a harmless, noninvasive procedure.

STOOL DNA TEST PREPARATION REQUIRED

You don't need to prepare much prior to undergoing a stool DNA test. You can drink and eat normally before taking the test. You don't need to adjust y our diet at all. You don't even need to discontinue any of your medications.

STOOL DNA TEST PROCEDURE

At the time of this writing, the stool DNA test presently available isn't FDA approved. However, a doctor can prescribe this test under special rules. You'll get a stool DNA test kit for collection and submission of your stool sample to the doctor's office. It can also be ordered online. The kit comes with a container that attaches to the toilet.

STOOL DNA TEST COMPLICATIONS

There are no complications associated with a stool DNA test. Because excretion of solid waste is a natural part of our daily routine, providing a stool sample for testing shouldn't involve infection or any invasive procedures.

STOOL DNA TEST SIDE EFFECTS

There are no side effects associated with a stool DNA test. The test itself is mostly concerned with studying the stool sample anyway, so no possible side effect will occur by taking a stool DNA test.

STOOL DNA TEST RESULTS

Once the results are in, you may get a negative result (DNA markers for colon cancer or precancerous polyps aren't present in your stool), a positive result (DNA markers for cancer or polyps have been found), a false-negative result (a negative result is incurred even though cancer is present), and a false-positive result (a positive result is incurred even though cancer is not present).
