Platelet count is 450. should i be worried?

Platelets : If it is 450, 000 do not be worried.

Not necessarily: If elevated persistently on repeat testing, then it should be checked out. Elevated platelets happen for several reasons. They are an acute phase reactant so if you are sick or recently had surgery, they can be high. Essential or primary thrombocytosis is a bone marrow disorder that causes you to make too many platelets. Hope this helps.
