Third menu expansion in four years broadens intestinal parasite detection in routine care

IDEXX Laboratories, Inc. (NASDAQ:IDXX), a global leader in pet healthcare innovation, today announced the expansion of its Fecal Dx™antigen testing platform with taeniid tapeworm, including Taenia and Echinococcus species. Proven to detect up to twice as many intestinal parasite infections earlier than fecal flotation alone,¹ Fecal Dx antigen testing delivers broader parasite detection in a single test for both wellness and sick-pet care.

IDEXX Fecal Dx™ antigen testing platform menu

Since launching in 2012, more than 50 million Fecal Dx antigen tests have been run worldwide,²reflecting strong clinical adoption over time. With each menu expansion, Fecal Dx has grown into a scalable diagnostic platform with increasing clinical scope and practice value.

"This advancement reflects how we innovate at IDEXX, developing platforms that grow with our customers as care evolves," said Mike Erickson, President and CEO of IDEXX. "By broadening the insight available through Fecal Dx, we're making fecal testing easier to incorporate into everyday decision-making, helping veterinary teams reach more pets with greater confidence."

Taenia and Echinococcus species are recognized by the Companion Animal Parasite Council (CAPC) as clinically important parasites,^3,4 with growing relevance for veterinarians worldwide. In particular, in areas where Echinococcus species is endemic, it can pose a significant zoonotic risk and remains a notable concern in parts of Europe, the United States and Canada. With this addition, Fecal Dx antigen testing now detects seven of the most clinically relevant intestinal parasite groups, including hookworm, roundworm, whipworm, flea tapeworm, taeniid tapeworm, Cystoisospora and Giardia (in select panels).

"The addition of taeniid tapeworm detection to IDEXX Fecal Dx makes this an even more complete intestinal parasite screen for cats and dogs," said Michael Rose, DVM, Managing Owner, Monticello Animal Hospital.* "This allows veterinarians to institute medical treatment early, which helps protect pet health and reduce zoonotic risk to owners."

Beginning in late June, Fecal Dx antigen testing panels and profiles for IDEXX Reference Laboratories customers in the United States and Canada will automatically include detection of taeniid tapeworm at no additional cost.
