Whether your child needs a simple blood test or more advanced laboratory procedure, we understand it can be a frightening experience for a child and difficult for parents.

Children’s Laboratory Medicine team makes sure patients and their families are as comfortable as possible, and explains everything that happens during a procedure. You can even stay to hold and comfort your child.

The division’s care team members are specially trained to draw blood from pediatric and special needs patients, and the laboratory technicians and technologists are trained to perform tests and procedures exclusively for children. This means we have the technical expertise and know-how to provide the best care for younger patients.

Additional Services

Our team works closely with all other care teams at Children’s National and with care teams across the region who count on us for their patients’ services. We can run specialized tests and help in the interpretation and diagnosis of chronic or rare diseases.

When insurance requires external commercial laboratory services, Children’s National is a Quest and LabCorp collection site. However, our physicians and nurses still review and discuss test results with you, and determine next steps in your child’s care plan.
