GI Infection Array Detects Many Diarrhea-Causing Pathogens, Eliminating Need for Numerous Individual Tests

Columbus, OH - July 2016

Gastrointestinal infections are caused by a broad spectrum of pathogens, and a number of detection methods may be employed before the correct pathogen is identified. Those methods, including fecal examination, bacterial culture and polymerase chain reaction testing, aren’t always specific and selective – and primary care providers may not always understand each method’s intended use.

The Gastrointestinal Infection Array, now utilized by Laboratory Services at Nationwide Children’s Hospital, helps alleviate many of those issues. The multiplex molecular testing targets 20 common GI pathogens that cause infectious diarrhea and results can be available in approximately an hour from receipt in the lab vs. 2-3 days:

“The array is meant to be ordered in place of conventional testing such as routine stool culture, ova and parasite examinations and antigen testing,” says Amy Leber, PhD, Director of Clinical Microbiology at Nationwide Children’s. “One of the benefits of the array is it can detect co-infections that cannot always be caught with the typical test ordering patterns.

Laboratory Services at Nationwide Children’s has found the array is comparable in cost to multiple tests on an individual stool specimen typically ordered by primary care pediatricians to detect diarrhea-causing pathogens.

Still some tests can be used with, or instead of, the GI Array as indicated below:
