AUSTIN, Texas, Jan. 15, 2013 /PRNewswire/ -- Luminex Corporation (NASDAQ:
LMNX) announced today that it has received FDA clearance for its xTAG
Gastrointestinal Pathogen Panel (GPP), the first comprehensive molecular
diagnostic assay that tests for greater than 90% of bacterial, viral, and
parasitic causes of infectious gastroenteritis in a single assay. The xTAG GPP
assay can be an important clinical tool in the management of gastrointestinal
infections, and is now available in the United States.


Diarrheal disease strikes more than two billion times globally each year and
is a leading cause of child morbidity and mortality worldwide^(1). In the
United States alone, 99 million cases of GI infection occur annually, leading
to over 250,000 hospitalizations^(2) and 17,000 deaths^(3), inflicting a
significant toll on the healthcare system. Diagnosis of some causes of
infectious gastroenteritis has traditionally required multiple tests across
the microbiology, virology, and molecular laboratories for which results may
not be available for several days.

As the first and most comprehensive multiplexed product of its kind in the
United States, xTAG GPP is a nucleic acid-based amplification assay that
simultaneously tests for 11 of the most common gastroenteritis causing
viruses, bacteria, and parasites. The panel includes: Campylobacter,
Clostridium difficile Toxin A/B, Escherichia coli O157, Enterotoxigenic E.
coli (ETEC) LT/ST, Shiga-like toxin producing E. coli (STEC) stx1/stx2,
Salmonella, Shigella, Rotavirus A, Norovirus GI/GII, Giardia lamblia and

Depending on the pathogen, currently available technologies and methods can
take several days to deliver a single result. xTAG GPP is capable of
delivering multiple results within 5 hours. The assay is cleared on the widely
available Luminex® 100/200™ system. Additionally, simultaneous molecular
testing on a single sample within a single shift provides significant benefit
to laboratories in terms of workflow and resource utilization.

"In our experience, simultaneous testing for multiple GI pathogens during
routine clinical testing and outbreak investigations enhances both our
diagnostic capabilities and public health laboratory efficiency," said Dr.
Sanjib Bhattacharyya, Deputy Laboratory Director at City of Milwaukee Health
Department. "Routine use of xTAG GPP will allow cost-effective, timely
detection of multiple pathogens, optimize use of laboratory resources, and
elevate our understanding of pathogen-associated diseases in gastroenteritis."

"CE IVD marked xTAG GPP has provided significant improvement to laboratories
and healthcare systems in Europe and other countries and we are pleased to
provide this important diagnostic to laboratories and patients in the United
States," said Patrick J. Balthrop, president and CEO of Luminex. "xTAG GPP has
the potential to enable hospitals to improve patient outcomes while saving
money. Our continued innovation is a reflection of the outstanding dedication
of our development team and our passion for creating breakthrough solutions to
improve health and advance science."

About xTAG GPP

The xTAG Gastrointestinal Pathogen Panel (GPP) is a multiplexed nucleic acid
test for the detection of multiple viral, parasitic, and bacterial nucleic
acids in human stool specimens from individuals with signs and symptoms of
infectious colitis or gastroenteritis.

The detection and identification of specific gastrointestinal microbial
nucleic acid from individuals exhibiting signs and symptoms of gastroenteritis
aids in the diagnosis of gastrointestinal infection and the investigation of
acute gastroenteritis outbreaks when used in conjunction with clinical
evaluation, laboratory findings, and epidemiological information. xTAG GPP
positive results are presumptive and must be confirmed by FDA-cleared tests or
other acceptable reference methods.
