Is 477 platelet count considered normal?

Answer 1

A normal platelet count is between 150,000 and 450,000 platelets per microliter (one-millionth of a liter, abbreviated mcL). The average platelet count is 237,000 per mcL in men and 266,000 per mcL in women. A platelet count below 150,000 per mcL is called thrombocytopenia, while a platelet count over 450,000 is called thrombocytosis.

Platelets seem to have a large backup capacity: blood typically still clots normally as long as the platelet count is above 50,000 per mcL (assuming no other problems are present).

Spontaneous bleeding doesn't usually occur unless the platelet count falls to 10,000 or 20,000 per mcL.

If you have listed yours without zeros, it is high (thrombocytosis). If there are no zeros, I am surprised you could ask this question.
