Quest Lab Gap Closure is a value-based program that proactively closes laboratory testing gaps year-round, helping payers simultaneously improve quality performance measure scores and member health outcomes.

Improve lab-related quality measures, such as HEDIS®

Increase the likelihood that lab services are completed for members who don’t have test orders in the normal course of care

Pay only for testing gaps closed through the program, after the measure year is complete

Rely less on providers to initiate testing

Quest Lab Gap Closure offers convenience at its core

Optimal member engagement strategies, including data analysis and proactive member outreach to increase compliance

Quality reporting tools for efficiently collecting and submitting data, and quarterly updates on program effectiveness

Prescriptive authority and physician oversight, reducing the burden on physicians to initiate testing for their patients while competing with other priorities

Lab Gap Closure Hub

The Lab Gap Closure Hub, accessible within the Quest Member Insights Portal, features a dashboard with service-based statistics, open and closed gap tracking, and additional metrics to help improve quality outcomes and test completion for critical gaps in care.
