Laboratory Services

Mercy Medical Group accesses the network of outpatient labs operated by Quest Diagnostics. All Quest Diagnostics Laboratory facilities are accredited by the College of American Pathology (CAP) and provide the same high level of care for outpatient services as is offered to patients in the hospital. If there is not a Quest Diagnostics lab in the Mercy Medical Group location where you are seeking treatment, there will be a lab within a mile of the clinic.
