What is hematology genetic counseling?

Hematology is the treatment and study of blood. Blood is made up of many components that are essential for bleeding, clotting, fighting infection and delivering oxygen throughout the body. Blood disorders can impact one or more of these processes and lead to harmful effects and health concerns.

While many factors may play a role in developing a blood disorder, some conditions result from underlying genetic changes. Identifying a hereditary (genetic) blood disorder can help us deliver the best treatment for your child and treat the same condition in other family members or future children.

About hematology genetic counseling at Children’s Colorado

At the Center for Cancer and Blood Disorders and the Hemophilia & Thrombosis Center, we offer genetic counseling to families with hereditary conditions. Talking with a genetic counselor helps you understand the genetic aspects of the disorder your child has. Our genetic counselors:

  • Assess your family’s chance of having a hereditary blood condition
  • Explore available genetic testing options, review results and discuss implications
  • Review how a condition is inherited and identify other family members who may also be impacted
  • Consider what steps you can take to prevent and detect symptoms of the disease
  • Evaluate reproductive health and options available to families with hereditary disorders
  • Assess family members’ risk for blood conditions and suitability as blood marrow donors for your child, if needed
  • Provide support resources and connections for families with the same or similar conditions
  • Connect families to research opportunities when applicable

Our genetic counselors hold master’s degrees from training programs accredited by the American Board of Genetic Counselors (ABGC)/Accreditation Council for Genetic Counseling (ACGC). They are also ABGC board-certified and actively involved in the National Society of Genetic Counselors.
