A stool sample is needed. There are many ways to collect the sample. You can catch the stool on plastic wrap that is loosely placed over the toilet bowl and held in place by the toilet seat. One test kit supplies a special toilet tissue that you use to collect the sample. When finished, put the sample in a clean container provided by your doctor's office. To collect the sample from a child in diapers, line the diaper with plastic wrap. If the plastic wrap is positioned properly, you can isolate the stool from the child's urine. Preventing the mixing of urine and stool will give a better sample. When finished, put the sample in a clean container provided by your doctor's office. Make sure you follow your doctor's instructions for returning the sample. Return the sample to the laboratory as soon as possible. The sample should not include toilet tissue or urine. The stool sample is sent to a lab where a small amount is placed on a slide. The slide is placed under a microscope and checked for the presence of abnormal organisms such as bacteria, fungus, or viruses. A stain may be applied that highlights certain organisms under the microscope. |
