What Physicians Need to Know

Patient Portal Integration
Quest AI Companion is an AI-powered chat feature seamlessly integrated into the secure, HIPAA-compliant MyQuest patient portal and mobile app. It allows adult users to analyze and understand their Quest laboratory test results without leaving the platform.
Appointment Scheduling AI
While the Quest AI Companion focuses on interpreting lab results, the MyQuest portal itself, where the AI Companion resides, enables patients to schedule appointments for sample collection and manage their existing appointments.
Symptom Checker Accuracy
Quest AI Companion is explicitly stated to be for educational purposes only and not for use in the diagnosis of disease or other conditions. It is not a symptom checker and cannot provide medical advice or diagnoses.
Multi-Language Patient Support
Quest Diagnostics provides language assistance services free of charge in English, Spanish, and Traditional Chinese, accessible via a phone number. This support is for Quest Diagnostics services in general, which would include MyQuest and by extension, the AI Companion.
Health Literacy Adaptation
The AI Companion aims to improve health literacy by explaining lab test results, medical terminology, and lab values in personalized, easy-to-understand language. It also helps patients prepare questions for their healthcare providers to facilitate more informed conversations.
Chronic Disease Management
The tool can analyze up to five years of an individual's Quest lab data to identify trends and patterns that may indicate health risks, which can be valuable for tracking chronic conditions and discussing them with a healthcare provider.
Patient Education Content
The primary function of Quest AI Companion is to provide personalized patient education by explaining lab test results, defining medical terms, clarifying reference ranges, and summarizing patterns across multiple tests.
Accessibility Compliance
Quest Diagnostics states that it complies with applicable federal civil rights laws and does not discriminate on the basis of race, color, national origin, age, disability, or sex. While not specifically detailing AI Companion accessibility, the MyQuest platform aims for broad accessibility.
Physician Tip

Encourage patients to utilize Quest AI Companion to better understand their lab results and formulate questions prior to appointments. Emphasize that the AI Companion is an educational tool to facilitate discussions, not a diagnostic or treatment recommendation system. Review the AI-generated summaries and patient questions to guide more focused and efficient consultations. Remind patients that the AI Companion only accesses Quest lab results and does not have a complete medical history, including medications or diagnoses, reinforcing the importance of comprehensive clinical context.

Quest AI Companion is powered by Google's Gemini family of models, a result of a strategic collaboration with Google Cloud established in March 2025. This partnership integrates Google Cloud's advanced AI technologies within Quest's secure, HIPAA-compliant MyQuest platform. The data sent to Quest AI Companion is kept separate from Google's public AI services and is not used to train any public large language models.
