The global pet antibody testing market is on a robust growth trajectory, projected to expand from USD 534.7 million in 2025 to USD 879.3 million by 2035, achieving a compound annual growth rate (CAGR) of 5.1% over the forecast period, according to the latest industry analysis.
Market Growth Drivers: Rising Pet Ownership and Preventive Healthcare
The surge in global pet ownership, coupled with heightened awareness of preventive healthcare, is significantly driving demand for pet antibody testing. This trend is further supported by increasing zoonotic disease surveillance, strict vaccination protocols for international pet travel, and the growing popularity of routine antibody titer checks among responsible pet owners.
“Antibody serology remains critical for detecting exposure to pathogens like heartworm, Lyme, and respiratory viruses in pets,” said Kevin Wilson, Chief Commercial Officer at Heska, a key player in veterinary diagnostics. Heska, recently integrated under Antech (Mars Petcare), introduced its Element i+™ Respiratory Profile, a multiplex antibody panel, in November 2023 to enhance veterinarians’ diagnostic capabilities.
