IDEXX Empowers Veterinarians with New Testing Insights that Support Earlier Diagnosis and Intervention for Preventive Care and Critical Cases

IDEXX Reference Laboratories Will Add Fecal Dx Antigen Testing with Flea Tapeworm Detection, Testing for the FGF-23 Kidney Biomarker, and Next-Day PCR Direct Testing Service

WESTBROOK, Maine, June 21, 2022—IDEXX Laboratories, Inc. (NASDAQ: IDXX), a global leader in pet healthcare innovation, announces new reference laboratory tests and services to help veterinarians gain insights during wellness screenings, develop treatment plans for cats with chronic kidney disease, and access fast, definitive answers for the most critical cases.

“The expansion of our reference laboratory menu demonstrates our continued focus on innovations that create clarity for our veterinary customers, supporting our shared mission to advance the standard of care for pets,” said Jay Mazelsky, IDEXX President and Chief Executive Officer. “The new offerings add to the unmatched customer experience at IDEXX Reference Laboratories, which includes access to specialists who offer personalized guidance, as an extension of the practice.”

Starting in September 2022, customers of IDEXX Reference Laboratories in North America will benefit from the following new tests and services:

  • Fecal Dx® antigen testing is expanded to include the detection of flea tapeworm in addition to current tests for hookworm, roundworm, and whipworm. Flea tapeworm is a common intestinal parasite that is transmitted anywhere fleas are found, and it may often remain undetected by testing methods like fecal flotation or other instrument-based optical methods that rely on the presence of eggs. With this addition, Fecal Dx antigen testing detects up to five times more of these common intestinal parasites, and earlier, than fecal flotation alone.1 This provides veterinarians with valuable insights as part of annual wellness screens and allows them to have more confident conversations with pet owners around treatment and prevention, supporting better patient outcomes. 
  • A first in North America, IDEXX is enhancing its suite of kidney health diagnostics with the addition of FGF-23, a kidney disease management biomarker. IDEXX FGF-23 provides quantifiable, evidence-based insights for veterinarians caring for cats with early chronic kidney disease (CKD),* enabling more confident treatment recommendations, such as dietary change. With IDEXX FGF-23 in addition to SDMA—the early indicator for a decline in kidney function—IDEXX has further enhanced the most comprehensive portfolio of renal diagnostic panels on the market today.
  • PCR Direct testing, a new service available through the opening of a state-of-the-art PCR laboratory. At no extra charge, IDEXX Reference Laboratories customers in the continental U.S. will have access to next-day PCR results, Monday through Friday, for their critical cases, including suspected zoonotic infections. By providing earlier access to diagnostic information, the next-day testing service enables veterinary professionals to start treatment for the most critical cases sooner, which can significantly improve patient outcomes.
