Final answer:
A normal platelet count is typically around 150,000/mm³ to 450,000/mm³. Low platelet count can cause uncontrolled bleeding, while a high count can increase the risk of blood clots.
Step-by-step explanation:
A normal platelet count is typically around 150,000/mm³ to 450,000/mm³. Platelets are small cells in the blood that help with clotting to prevent excessive bleeding. If the platelet count falls below 150,000/mm³, it is considered low (thrombocytopenia), which can lead to uncontrolled bleeding. On the other hand, if the platelet count goes significantly above the normal range, it can increase the risk of blood clots.
