Question

Quizplus · Accepted Answer

A platelet count of 650 x 10^9/L is above the upper limit of normal (150-450 x 10^9/L). However, the absence of any other abnormalities in hematology tests and the lack of evidence of hemostasis failure suggest that it is reactive thrombocytosis. Essential thrombocythemia, DIC, and polycythemia vera will typically present with other abnormalities in hematology tests and may present with evidence of hemostasis failure.
