Laboratory Notice Regarding COVID-19

You are a valued part of our Greenwood Diagnostic family, and we remain dedicated to you and your patients.

We are accepting specimens on our normal schedule and are not experiencing any testing delays at this time. We will keep you updated on any changes as we navigate these uncertain times together.

As clinic schedules are modified and more patients are being seen via telehealth, we can continue to serve your genetic testing needs with the following resources:

If you have an urgent request, please call the lab at 1-800-473-9411.

Thank you for your continued support of Greenwood Diagnostic Labs.

The diagnostic lab at Greenwood Genetic Center is named to honor the Center’s co-founder, Harold A. Taylor. The facility is made of three separate, but integrated laboratories: the biochemical lab, the cytogenetic lab and the molecular lab. All three laboratories use technologies to help physicians, patients and their families to better understand a disorder and the available treatments for it. The Greenwood Diagnostic Labs utilize traditional and cutting-edge tools such as next-generation sequencing, multiple array CGH platforms and expanding enzyme analysis testing to provide the most accurate and reliable diagnoses available. 

Lab requisitions must accompany all samples, and they should be completed by the referring physician or other healthcare provider. The process of ordering tests has been streamlined with our downloadable requisition forms and test finder. A complete list of test CPT Codes and Prices is also available. The test finder lists over 300 tests and general information for each test including:

  • Methodology
  • Specimen requirements
  • Turnaround time
  • CPT Codes
  • Costs

Laboratory faculty and staff are an invaluable part of GGC’s patient care team. They work closely with clinicians to facilitate testing and support genetic counselors and referring physicians with the information they need to provide answers to their patients.

One Mother's Story

After a long three-year struggle trying to have children, our son, Charlie, was born on April 18, 2009. He was our miracle...perfect in every way! When Charlie was five days old, our pediatrician called to notify us that one of the numbers from the heel prick test was a bit high. We headed to the hospital that afternoon for more tests. I will never forget the following day. It was cool and crisp - not a cloud in the sky. The next thing I know, our ...
