Improving Quality Patient Care Through Accurate Diagnostic Testing

The mission of Medical Laboratory Evaluation (MLE) is to administer a service-oriented laboratory proficiency testing program that provides the technical and educational tools necessary to assess, monitor and improve the quality of laboratory testing.

For over 40 years, MLE, a service of the American College of Physicians, has provided reliable, user-friendly laboratory proficiency testing (PT) services at a substantial cost savings for those labs that perform diagnostic testing where blood and bodily fluids are drawn. Our clients include a wide array of public and private clinical laboratories in over 50 countries.

MLE is approved by CMS, COLA, TJC, US state agencies and International regulatory bodies.

Are you CAP accredited? Whether you use MLE as your primary or secondary laboratory proficiency testing provider, you'll save on PT for the CAP accepted analytes that we offer and we'll even waive the annual administration fee your first year with us! When you order, select discount offer #10.
