GI Effects^TM Stool Profiles

Frequently Asked Questions

1. What is the minimum specimen requirement for this test?

The level of fluid in the collection tubes must come up to the line once the specimen is collected. Be aware, it takes only a small amount of specimen to meet the requirements so begin with a very small amount and add more until the requirement is met. This will prevent spillage

2. How long do I have once the specimen is collected to get it to the laboratory? (Please see proper specimen storage under the “Shipping” section)

The stool specimen must be received within 5 days of the initial collection.

3. What is the difference between the Metametrix GI Effects test and other standard testing?

The GI Effects tests utilize DNA analysis, the advantages of which include far greater accuracy, fewer samples to be collected, and the ability to measure previously immeasurable areas of the gut environment. Whereas many laboratories split testing into several costly profiles, yeast, inflammation, parasites, bacteria, pharmaceutical and botanical sensitivities and more are all included in the Metametrix profile.

4. For what issues might the GI Effects Stool Profile be useful?

Irritable bowel syndrome, inflammatory bowel disease (IBD), Crohn’s disease, ulcerative colitis, constipation, bloating, diarrhea, cramping, maldigestion, gas, blood in stool, headaches, and eczema are all conditions whose treatment may be informed by the Profile. The test is prudent if a family history of celiac disease or other autoimmune bowel diseases is present.

5. I spilled some of the liquid out of one of the vials. What should I do?

First, carefully clean up the spilled liquid and wash hands/skin thoroughly. It is imperative that we have the correct amount of liquid and stool sample in each vial so you will need to recollect - call Metametrix Client Services (800-221-4640) to request new tubes.

6. Can I collect a stool sample from a diaper?

Yes, if this is the only way to get a patient’s specimen. The specimen is best if formed as the diaper can absorb a more liquid specimen. Try to avoid contamination with urine as it can dilute the specimen.

7. I misplaced or broke the cardboard collection container, what else can I use?

You could use a paper bowl or paper plate – anything that is clean, non-porous, and disposable. The collection container only needs to be clean, NOT sterile.

8. I accidentally got urine in the collection as well, is my specimen still good?

No, you will need to recollect the specimen.

9. There is blood in my stool, is the sample still good?

If the blood is due to menstruation, you should wait and collect again after menstruation or use a tampon in another collection. If the blood was part of the stool and came from the bowel it will be tested and does not interfere with the rest of the test. Blood is one of the components tested in the GI Effects Stool Profile.
