Hematology

When most of us think of blood, we think of the red stuff in our veins, or boo boos that are quickly fixed with a bandage and a kiss. But for some kids and teens, there's a lot more to it.

Unless your child is diagnosed with a blood disorder or disease, chances are you've never given much thought to the word hematology or all of the functions of blood that our bodies depend upon. But if your child has been diagnosed with a blood disease or disorder, Cook Children's hematology team is here to help make things better.

Living with Hemophilia: Stories of Resilience

Any time a child gets a bump, cut or bruise, it's a scary moment for parents. Most of the time a bandage will mend things, but for a parent whose child has a bleeding disorder like hemophilia, it's a slightly different story.

Common referral diagnoses:

Cook Children's hematology team cares for children and teenagers with diseases of the blood that are non-malignant. Due to the fact that the blood system and clotting system are so complex, there is a broad range of disorders and diseases evaluated and treated by our hematology physicians. These include, but are not limited to:

In the past, many of these diseases and disorders would have prevented kids from participating in daily activities. Today, the hematology team at Cook Children's evaluates each case and, based on the condition he or she is diagnosed with, the patient is provided with an individualized treatment plan and guidelines to maximize a healthy lifestyle and minimize hospitalization.

Every tissue in the body depends upon the blood. For that reason, your care team has experience in multiple specialties and includes physicians, a nurse practitioner, dedicated nursing staff, a hematology data coordinator and support services such as Child Life, social services, physical therapy and neuropsychology.
