How does a doctor know if a child has a platelet function disorder?

Platelet function disorders can be identified through the following tests:

  • bleeding time, which measures how long it takes for a cut to stop bleeding
  • complete blood count
  • additional blood and urine tests (to measure clotting times and detect possible infections)
  • possible bone marrow testing to identify any abnormal cells
  • careful review of your child's medications

A full bone marrow exam in which samples of the fluid (aspiration) and solid (biopsy) portions of bone marrow are withdrawn with a needle under local anesthesia may also be performed.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
