Lab outreach services

Ensure your outreach program is a competitive advantage

Lab outreach programs offer a valuable service to the community, help your lab operate closer to capacity, and support your health system's overall strategy, but managing the process isn’t always easy. 

If your hospital offers laboratory outreach programs that serve physicians in your community, Quest may be able to complement and enhance your efforts by improving quality, increasing efficiency, and lowering costs with our laboratory outreach solutions. 

Phlebotomy services

We can optimize your draw network, including the location of patient service centers and staffing phlebotomists.

Turnaround times

With our vast network of regional and esoteric labs and Patient Service Centers, we can help you reduce turnaround times.

 Logistics

We can manage specimen transportation for you—using our network or yours.

We can manage billing, leveraging the strength of our payer relationships, and ultimately help to reduce administrative complexity.
