Our Children's Oncology Group team provides more than a test result. We work to establish relationships with care providers, clinical research assistants, and clinical staff to provide the best patient care. Our physicians offer test-ordering recommendations and provide trusted opinions on a case-by-case basis. Because of our large COG test volumes, we employ a dedicated COG team with laboratorians, technical specialists, and laboratory directors focused on pediatric patient cases. Our team:

  • Reviews and submits all COG paperwork for approval in clinical trials.
  • Offers testing on all specimen types, including bone marrow, blood, formalin-fixed paraffin-embedded tissue, and more.
  • Provides customized, interpretive reports for even the most complex cases.
