The team of medical professionals at the Marian Professional Building Laboratory Services seeks to be a community health resource for your non-emergent medical needs. Our team takes the time to ensure the comfort of our patients, as we provide the highest quality blood testing, perinatal testing, and nutritional counseling services. 


Blood Testing – Catholic Health laboratory services test and process blood locally, allowing for fast, same-day results. Our locations offer an extensive catalog of blood tests, helpful in diagnosing disease, measuring risk factors, and evaluating a patient's overall health. On the day of your visit, be prepared with a prescription, identification, and insurance information. Make sure to follow any specific instruction from your doctor as well.

Perinatal Testing – During pregnancy, several tests to monitor your baby’s health and growth are necessary. If you do not plan on delivering at a Catholic Health facility, we will ensure that your provider receives the results of your tests as soon as possible in order to efficiently manage any medical complications. Make sure to bring your prescription, insurance, and identification to your appointment.

Nutrition Counseling – Counseling sessions with our expert dietitians provide a way for patients to examine how their lifestyle and diet are reflected in the way they feel. We hold ourselves to the highest standard of care by taking the time to understand patient concerns and observing your privacy.
