We offer a full range of lab testing services. Test results are immediately transmitted to your physician’s office. Patients may also have specimens collected and tested here and the results sent to a specialist in another city. In addition to routine lab tests most often requested by your physician, we also provide health screens to promote wellness and reduce health risks in our community.
