Latest Molecular Diagnostics Technology Aids German Hospital in Management of European E. coli Crisis

AUSTIN, Texas and KOLN, Germany, June 8, 2011 -

- New CE Marked xTAG(R) Gastrointestinal Pathogen Panel (GPP) Used to
Triage Patients at German Kliniken der Stadt Koln

Luminex Corporation (NASDAQ: LMNX) and the Kliniken der Stadt Koln,
Institute of Pathology and Institute for Hygiene today announced that
Luminex's newly released xTAG(R) Gastrointestinal Pathogen Panel (GPP) is
being used successfully as a first-line screen for patients at Kliniken der
Stadt Koln suspected of having an E. coli infection. This includes the
detection of hemolytic-uremic syndrome (HUS) causing Shiga-like toxin
producing E. coli strain responsible for the current outbreak.

Kliniken der Stadt Koln Institut fur Pathologie worked with Luminex last
week to quickly implement this new diagnostic assay when they successfully
showed xTAG GPP was able to accurately detect the outbreak pathogens in
patient samples.

As of 7 June at 15:00 CET World Health Organization (WHO) reported 2,745
people in 12 European countries have been sickened by E. coli. Since the
beginning of May, there have been 722 notified cases of HUS and 25 deaths -
nineteen fatalities resulting from HUS infections and six fatalities from E.
coli non-HUS infections. Staff at Kliniken der Stadt Koln Institut fur
Pathologie, who use the Luminex xTAG Respiratory Viral Panel (RVP), have
quickly adopted xTAG GPP as an important first line screen to help manage the
current outbreak in Germany.

Since xTAG GPP can rapidly and simultaneously identify 95% of acute
gastroenteritis pathogens, infected patients can be quickly identified and
appropriately managed. Positive STEC patients can be closely monitored and
treated in parallel with confirmatory testing. Additionally, patients who are
infected with other causative infectious agents; or those who are negative,
can be quickly identified and receive appropriate care or be discharged, thus
making healthcare resources available to those most in need.

"Prior to the approval last month of xTAG GPP, we did not have a test
that would allow us to rapidly detect a comprehensive array of
disease-causing pathogens for infectious gastroenteritis," said PD Dr. Frauke
Mattner, of Kliniken der Stadt, Institute of Pathology and Institute for
Hygiene. "The ability of xTAG GPP to detect not only several different types
of E. coli, but also the presence of the Stx-2 gene, a key marker of this
more severe STEC strain, is allowing rapid identification of patients who may
be suffering from an infection of this outbreak strain. This innovative
technology is an important advance and an invaluable tool in the management
of the current crisis."

"We are pleased and proud that our new innovative assay, xTAG GPP, is
helping health care professionals in Germany rapidly identify patients who
may be infected with this pathogen and is assisting them during this crisis,"
said Patrick J. Balthrop, president and CEO of Luminex. "All of my Luminex
colleagues across the globe share a serious concern for those affected and
hope for a resolution to the current situation as quickly as possible."

About xTAG Gastrointestinal Pathogen Panel (GPP)

Luminex's xTAG GPP can simultaneously detect fifteen of the most common
disease-causing gastrointestinal pathogens, including viruses, bacteria and
parasites, such as E. coli, Campylobacter, Salmonella and C. difficile all
within 5 hours. xTAG GPP received CE mark approval in May of 2011 from
European regulatory authorities and is now being used as an important aid for
patient triage in the current outbreak.
