Is it abnormal to have 54000 platelets?

Answer 1

Yes it is abnormal. More information: Normal platelet counts for children and adults are between 150,000-400,000 per mm3. For babies, normal limits are 200,000-475,000, and for newborns, normal would be 150,000-300,000 mm3. Platelets are responsible for blood clotting, so a low count count would put the person at risk for uncontrolled bleeding.
