CASE STUDY (#24-28): Cameron is a 7 year-old girl who has an obvious petechial rash, along with other bleeding symptoms. Her physician orders coagulation screening tests, and here are the results: Platelet Count – 276,000/μL             PT – 12 seconds;              aPTT – 27 seconds  The physician decided to order platelet aggregation studies.  Results from the platelet aggregation studies were as follows:ADP –abnormal 2nd wave (normal 1st wave)        Collagen–abnormal        Epinephrine–abnormal 2nd wave (normal 1st wave) Ristocetin-normal What do Cameron’s platelet aggregation study results indicate?
