Quest Diagnostics Launches AI Companion to Help Patients Interpret Lab Test Results

The tool is now available to adult users through the company’s secure patient platform, MyQuest, including its mobile app and web portal.

Quest Diagnostics has introduced Quest AI Companion, an artificial intelligence-powered chat feature designed to help patients analyze and understand their laboratory test results.

The tool is now available to adult users through the company’s secure patient platform, MyQuest, including its mobile app and web portal.

The AI-powered feature enables users to ask questions about their test results and receive immediate, personalized explanations without leaving the HIPAA-compliant MyQuest environment. According to the company, the tool can analyze up to five years of an individual’s laboratory data from Quest reports to identify patterns and trends that may indicate potential health risks.

Quest AI Companion is designed to help individuals better interpret medical terminology and laboratory values. Users can ask the tool to define test names, explain whether results fall above or below reference ranges, and translate medical language into simpler explanations. The system can also assist patients in preparing questions to discuss with their healthcare providers, with the goal of supporting more informed conversations during clinical visits.

“Patients often tell us they want help simplifying and understanding their test results and what the results communicate about their health,” said Nicole Antonson, vice president of digital solutions and interoperability at Quest Diagnostics. “Quest AI Companion builds on this history and empowers patients to analyze their results and spot trends they can discuss with their healthcare provider.”

The feature operates within Quest’s existing digital infrastructure, allowing users to access their laboratory data directly without uploading personal health information to public AI platforms. The company said this approach addresses concerns about privacy and data security that many individuals associate with external AI tools.

Quest Diagnostics cited survey findings indicating that although generative AI use is expanding in healthcare, many individuals remain hesitant to use public AI applications to interpret personal health information due to concerns around reliability, accuracy, and data protection.

“People want to understand their lab data, but not everyone feels comfortable uploading their health data to public AI platforms,” said Yuri Fesko, M.D., senior vice president and chief medical officer at Quest Diagnostics.

Quest AI Companion is powered by Google Cloud’s Gemini family of AI models and stems from a collaboration between Quest Diagnostics and Google Cloud announced in March 2025. The partnership focuses on applying advanced AI technologies to improve data management and patient engagement tools.

The company said the feature is intended for educational purposes and is not a substitute for professional medical advice. Patients are advised to consult healthcare providers regarding test results and treatment decisions.
