platelets are the tiny cells that circulates around the body through blood. if blood test shows high platelets it is danger as it have no capacity to fight with the infection. so it is not good to health. it will be not good for blood clotting.
It could mean a lot of things. It is normal for people who exercise a lot, just had a baby, or live at high altitudes. If your platelets are still sticky, they can stick together and cause an embolism.
First talk this over with your doctor. Ask him the risks of having this. It is different for the young and old. It could be serious. I have a high count. Many years ago I give the platelets to a cancer patient, at that time I was told it would help their immune system.
