Then place the stool sample in a clean, sealable container before taking it to the lab. Plastic wrap can also be used to line the diaper of an infant or toddler who isn't yet using the toilet. The wrap should be placed so that urine runs into the diaper, not the wrap. Your child shouldn't urinate into the container. If possible, have your child empty his or her bladder before a bowel movement so the stool sample isn't diluted by urine.
The stool should be placed into clean, dry plastic jars with screw-cap lids. Your child may be asked to provide a stool sample one or more times. For best results, the stool should be brought to the lab within a few hours. Getting the Results In general, the result of the stool culture is reported within 24 to 48 hours.
Risks No risks are associated with collecting stool samples. How should I collect and store a poo stool sample? You should: collect your poo stool sample in a completely clean sterile container store the container in a fridge in a sealed plastic bag if you can't hand it in straight away Collecting a stool sample Your GP or another healthcare professional, such as a nurse, should explain how to collect the sample.
To collect the sample: label a clean, screw-top container with your name, date of birth and the date place something in the toilet to catch the poo, such as a potty or an empty plastic food container, or spread clean newspaper or plastic wrap over the rim of the toilet make sure the poo doesn't touch the inside of the toilet use the spoon or spatula that comes with the container to collect the poo, then screw the lid shut if you've been given a container, aim to fill around a third of it — that's about the size of a walnut if you're using your own container put anything you used to collect the poo in a plastic bag, tie it up and put it the bin wash your hands thoroughly with soap and warm running water Follow any other instructions your doctor has given you.
Storing a stool sample Your sample of poo must be fresh — if it is not, the bacteria in it can multiply. What are stool samples used for? Poo contains bacteria and other substances that are in the digestive system. Some conditions will be detectable without a microscope, for example some species of worms are very clear to see without any technology.
Other species of worms, however, are smaller and harder to see. Again, there are many different kinds of stool tests to detect many different conditions.
Below you can find a list of some of the most common conditions your doctor would look for with a stool test.
Two types of stool tests are used as screening tools for colorectal cancer, or the precancerous cells that can lead to cancer. The older test finds hidden blood in the stool. A newer test looks at DNA in the stool for evidence of colorectal cancer.
However, if either the stool DNA test or the hemoccult test is positive, you will still need a colonoscopy to find and remove the precancerous or cancerous lesion.
A common initial test for IBD measures calprotectin levels in stool. Calprotectin is a protein that is found in white blood cells and it has strong antibacterial and antifungal properties. Calprotectin rises when inflammation occurs whatever the cause of that may be. The concentration of calprotectin relates directly to the severity of the inflammation: the more severe your IBD, the higher your calprotectin levels will be.
To look for pancreatic insufficiency, you can get a test that measures elastase in your stool. Elastase is an enzyme made by special tissue in the pancreas, an organ in your upper abdomen. Elastase helps break down fats, proteins, and carbohydrates after you eat. This depends on what kind of stool test you use. And do not do the test during your menstrual period or if you have active bleeding from hemorrhoids. If you aren't sure about how to prepare, ask your doctor. Do not use a stool sample for testing that has been in contact with toilet bowl cleaning products that turn the water blue.
Stool samples can be collected at home, in your doctor's office, at a medical clinic, or at the hospital. If you collect the samples at home, you will be given stool collection kits to use each day.
Each kit contains applicator sticks and two sterile containers. You may need to collect more than one sample over 1 to 3 days. Follow the same procedure for each day. Take the sealed container to your doctor's office or the lab as soon as you can. You may need to deliver your sample to the lab within a certain time.
Tell your doctor if you think you may have trouble getting the sample to the lab on time. If the stool is collected in your doctor's office or the hospital, you will pass the stool in a plastic container that is inserted under the toilet seat or in a bedpan. A health professional will package the sample for lab analysis. You will need to collect stool for 3 days in a row if the sample is being tested for quantitative fats. You will start to collect stool on the morning of the first day.
The samples are placed in a large container and then refrigerated. You may need to collect several stool samples over 7 to 10 days if you have digestive symptoms after travelling outside the country. Sometimes a stool sample is collected using a rectal swab that contains a preservative. The swab is inserted into the rectum, rotated gently, and then withdrawn. It is placed in a clean, dry container and sent to the lab right away.
The test will take a few minutes each time you take a sample. There is no pain while collecting a stool sample. If you are constipated, straining to pass stool may be painful. If your health professional uses a rectal swab to collect the sample, you may feel some pressure or discomfort as the swab is inserted into your rectum. Any stool sample may contain germs that can spread disease. Make sure to carefully wash your hands and use careful handling techniques to avoid spreading infection.
Each lab has a different range for what's normal. Your lab report should show the range that your lab uses for each test. The normal range is just a guide.
