Idexx Laboratories reported strong third quarter earnings Tuesday, with revenue up 10 percent and net income up 29 percent from the same period a year earlier.

The Westbrook-based maker of veterinary diagnostic tests reported revenue of $448.3 million for the quarter, a 10.3 percent increase over the third quarter of 2015. Its net income of $56.5 million, or 62 cents per share, was up 29 percent.

The company’s net income for the quarter beat analyst expectations by 2 cents per share, while revenue fell short by $350,000, according to online investor service Seeking Alpha.

Idexx Chairman and CEO Jonathan Ayers attributed the company’s results to strong growth in pet health care, including the increasing use of diagnostics, which he said is supported by a “deeply-rooted, global trend of the strengthening bond between humans and their pets.”

“With sustained strength in our global markets, our third quarter results reflect the power of our durable, recurring revenue business model,” Ayers said in a news release. “Momentum continues to build in our commercial organization, as customers accelerate their adoption of our latest stream of innovations based on sound clinical evidence and the beneficial impact on their practices’ economics.”

Idexx trades on the Nasdaq exchange under the symbol IDXX. Following Tuesday morning’s earnings release, its stock price opened at $110.05, up 2.7 percent from Monday’s closing price of $107.14.
