Genomics and Pathology Services (GPS), a collaborative initiative between the Department of Pathology & Immunology and the Department of Genetics, is a clinical genomics laboratory at Washington University School of Medicine in St. Louis.

Located in the state-of-the-art Cortex building, our CAP-accredited, CLIA-certified laboratories deliver clinically validated testing supported by extensive clinical and genomic experience and advanced technologies.

GPS’ clinical genomic tests improve patient care by enabling a personalized approach to medicine. Our next-generation sequencing tests return actionable genomic intelligence across multiple key disease-relevant genes.

Sequencing results are interpreted by board-certified pathologists and clinical geneticists. Variants are categorized by medical significance in a concise clinical report. These results help ordering physicians stratify disease subtypes and identify optimal patient treatment strategies.
