How is fecal test done

1. You can cover the stool with a plastic wrap that is slackly placed over the toilet bowel and kept in place by the toilet seat. Then put the sample in a sterilized container. You can also take a test kit from the medical lab, which contains a special sterilized spoon to collect a stool sample and put it in a clean container.

2. In case of infants with diapers, line the diaper with plastic wrap. If this wrap is lined well, then there will not be any mixing of stool and urine, which in turn, can be an appropriate sample for analysis.

3. The stool in a special container is named, with date and time put before it is sent to the laboratory for analysis.
