Knowing what matters in Indiana
Transforming knowledge into insights and insights into solutions
Quest Diagnostics is proud to welcome the healthcare providers, patients, and community of Mid America Clinical Laboratories (MACL). MACL has been acquired by Quest Diagnostics, and you will continue to enjoy services as you have previously, plus be able to take advantage of new benefits through Quest. As part of this transition, you will start to notice changes occurring with removal of the MACL name, logo, and other similar items. With these changes comes access to new services and solutions.
You now have expanded access to specialized and advance testing
We also work with you to help engage your patients in their own health. Your patients can take advantage of our more than 30 Patient Service Centers across Indiana, online appointment scheduling and test results, and our broad insurance coverage.

We feel privileged to count you among our clients and customers. We look forward to working together toward better health. Click on the below depending on what you are looking for to explore Quest Diagnostics:
