Platelet Esoteric Testing

A Case Study

Differential Diagnosis ?

Slide 10

June 2010

Based on these laboratory results, here are some potential differential diagnoses:
1. Her bleeding is most likely caused by thrombocytopenia, a quantitative platelet deficiency, since there is no evidence of a qualitative platelet disorder. 2. Qualitative platelet dysfunction present (detected by prolonged PFA100-Epinephrine closure time). 3. Patient most likely has persistent ITP. 4. In light of patient’s significant bleeding history and abnormal peripheral blood findings, further platelet testing is indicated. We favored number 4, therefore we further pursued additional testing.
