Meretek Diagnostics Announces BreathTek(TM) Testing Services Agreement With PAML

LAFAYETTE, Colo., April 3 /PRNewswire/ -- Meretek Diagnostics, manufacturer of the BreathTek(TM) UBT urea breath test for the bacterium Helicobacter pylori (H. pylori), has signed a testing services agreement with Pathology Associates Medical Laboratories (PAML) of Spokane, Wash., the largest independent laboratory in the Northwest.

Under terms of the agreement, PAML will provide testing services for Meretek's BreathTek UBT urea breath test. BreathTek UBT is a simple, non-radioactive, non-invasive, 95 percent sensitive and specific solution to diagnose and monitor treatment of active H. pylori infection, the leading cause of peptic ulcers.

"We were impressed with PAML's commitment to excellence and reputation as an industry leader," said Meretek President and Chief Executive Officer, Ryuichi Kishigami. "When it came to finding a reference lab to support testing for our products in this region, the choice was clear."

PAML operates a state-of-the-art, full-service reference laboratory and maintains other laboratory operations throughout the western U.S. The laboratory delivers a wide range of testing services to more than 90 hospitals in Washington, Idaho, Montana, Oregon, California, Utah and Alaska.

The BreathTek UBT is the only breath test for H. pylori that is FDA-cleared to confirm that a patient is cured after undergoing antibiotic therapy. Approximately 1 in 3 adults in the U.S. is infected with H. pylori. One in ten Americans may develop a peptic ulcer over their lifetime. Eighty to 90 percent of peptic ulcers are caused by an H. pylori infection.

Meretek products also include the UBiT(R)-IR 300 infrared spectrophotometer and POCone(TM) infrared spectrophotometer. For a complete listing of features and benefits of the BreathTek(TM) UBT, visit http://www.meretek.com/physician_testing.asp.
