GI Pathogens Profile, Multiplex PCR-Doctor's Data Kit

Note: This is a home collection test kit that will be mailed to you.



Fasting Required: No

Specimen: Stool

Lab: Doctor's Data

Results: 2-5 business days
Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Special Instructions: If you are taking anti-fungal or antibiotic medications, please finish the course of medication, and then wait three days before starting this collection. Please refrain from taking digestive enzymes, laxatives (particularly mineral oil and castor oil), antacids, aspirin, and substances containing barium and/or bismuth for two days prior to and during the specimen collection, unless otherwise instructed by your physician.

Never discontinue prescription medications without first consulting your physician.

Description: The GI Pathogen Profile, uses multiplex PCR system, tests for 14 Viruses, parasites, and bacteria, and offers new opportunities for the rapid, accurate diagnosis and prompt treatment of diarrheal illnesses which can improve patient outcomes and clinical success.

While bacteria and parasites are the primary cause of food & water-borne diarrheal illness (48 million infections/year), the vast majority of acute diarrheal illness is caused not by bacteria or parasites, but by viral infections. In fact, Norovirus is the primary gastrointestinal infection occurring in the United States. Even though testing for pathogenic bacteria and parasite is commonly available, there has been limited availability of viral testing until recently.

Acute gastroenteritis may contribute to patient morbidity and even mortality, if the illness progresses to severe dehydration. Also, the identification of reportable diseases is imperative to prevent large outbreaks, especially for highly contagious or food-borne illnesses, and many gastrointestinal illnesses have very similar clinical presentations.

Most GI Pathogen Profile results can be provided within one business day of sample receipt with 99.9% overall negative predictive value. As a result, you can begin targeted treatment immediately, for greater therapeutic efficacy and reduced risk of complications & side effects associated with incorrect treatment or unwarranted antimicrobial administration.

Rapid diagnosis allows for better treatment decisions, as antimicrobial agents have no effect on viral illness, and the indiscriminate use of antibiotics may increase bacterial resistance. Certain pathogenic bacterial and parasitic infections may require antimicrobial treatment, while other infections warrant rehydration and supportive therapies. Knowing the difference allows the treating physician to practice good antimicrobial stewardship.
