How do you do a fecal occult blood test?

ANSWER

You can buy some kits at the pharmacy, or your doctor may give you a home test kit at one of your appointments. They come with instructions. Most list a phone number to call if you have questions.

For some tests, you put a special pad or tissue from the kit into the toilet and tell your doctor if it changes color.

For others, you'll collect stool samples on more than one day. Then you send the samples, in a special container and envelope, to your doctor's office or a lab where they're checked with a microscope or chemicals. You should use newer “high sensitivity” versions of these tests.
