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A full bone marrow exam in which samples of the fluid (aspiration) and solid (biopsy) portions of bone marrow are withdrawn with a needle under local anesthesia may also be performed.
