correct, high HB and HCT isnt a problem when platelets are normal. its a normal reaction to hormones, body is getting more optimised. BUT when platelets go up, then there is danger of clotting and thats the last thing you want.

check if you have polycythaemia vera. genetic disorder where the body produces not more red blood cells but also white cells and platelets

keeping platelets in the normal is very important

interestingly you have LOW RBC's but high platelets: this could indicate an IRON issue, so be sure to test the following: total iron, transferrin, iron saturation and very very importantly your ferritin
