Is 500 a high platelet count?

The most common reason for an elevated platelet count is reactive thrombocytosis. Lifetime reactive thrombocytosis may also be present in patients who have had a splenectomy. Recent studies have found that between 87% and 96% of people found to have platelet counts over 500,000/μl had reactive thrombocytosis.

Keeping this in consideration, what is considered high platelet count?

In general, a platelet count more than 450,000 cells per microliter is considered elevated; this is known as thrombocytosis. There are numerous causes of thrombocytosis and fortunately, the majority are benign and transient.

Beside above, is 400 a high platelet count? Normal platelet counts are in the range of 150,000 to 400,000 per microliter (or 150 - 400 x 109 per liter), but the normal range for the platelet count varies slightly among different laboratories. Mild to moderately elevated platelet counts are commonly seen when chronic inflammation is present.

Subsequently, question is, what level of platelets is dangerous?

A count lower than 150,000 is considered thrombocytopenia and may affect your ability to donate platelets, among other things. A platelet count below 10,000 is considered severe thrombocytopenia. When your platelet count gets too low, it can cause dangerous internal bleeding.

Is 600 a high platelet count?

Thrombocytosis is defined as a platelet count above the normal value, in general more than 400,000 to 600,000/mm3 or more than 400 to 600 × 109/L (normal in adult humans, 150 to 450 × 109/L). Secondary (reactive) thrombocytosis is due to a variety of underlying conditions involving an acute phase reaction.
