21 , 22 Also, in another recent study, it was found that although there was an increased incidence of bleeding events during delivery in women with inherited thrombocytopenia and a platelet count of <50 × 10 9 L −1 , the increased incidence did not seem to be linearly correlated with platelet counts, as the odds ratio (OR) for bleeding events showed a nonsignificant trend towards lower incidences of bleeding in the tertile of platelets with a platelet count of 49‐80 × 10 9 L −1 in comparison with patients with a platelet count of > 80 × 10 9 L −1 . 23 These observations indicate that clinical decision making needs to be based on knowledge regarding both quantitative and qualitative defects in primary hemostasis.

Our results demonstrate dramatic and highly significant effects of sample platelet count on aggregation responses in the tested platelet count interval (Figures 1 G,H and 2 G,H).
