Idexx Laboratories (IDXX)

Its companion animal business is the core of the company. IDEXX supplies in-clinic analyzers for chemistry, hematology, urinalysis, and other testing, along with single-use diagnostic kits for common canine and feline conditions. These products allow veterinarians to produce results during a patient visit, improving the speed of diagnosis and treatment decisions. IDEXX also operates a network of reference laboratories that handle more complex or high-volume testing for veterinary clinics.

Beyond diagnostics, the company provides practice management software, client communication tools, and data services used by animal hospitals to run daily operations. These products connect clinical testing with appointment scheduling, medical records, billing, and customer engagement, making IDEXX an important technology supplier as well as a laboratory and medical device company.

IDEXX also serves livestock and poultry markets with tests used to detect, monitor, and manage infectious diseases in herd and flock health programs. In addition, the company has businesses related to water testing and other diagnostic applications.

Listed under the IDXX symbol, IDEXX benefits from long-term trends such as rising pet ownership, greater spending on companion animal care, and increased use of diagnostics in veterinary medicine. A meaningful portion of its revenue comes from outside the United States, giving the company exposure to international growth in pet healthcare and food animal disease monitoring.
