There is still a possibility that Bryson could have a coagulation disorder. A detailed patient history could give us details to assist in making the proper diagnosis.

Specific questions to ask could include:

  • Have you noticed prolonged oozing after a finger or heel stick?
  • Are his bruises often raised?
  • Has he ever had surgery?
  • Were there any problems with bleeding?
