What does it mean when your blood count is high?

If your white blood cell count is higher than normal, you may have an infection or inflammation. Or, it could indicate that you have an immune system disorder or a bone marrow disease. A high white blood cell count can also be a reaction to medication.

What happens if platelet count is high?

A high platelet count can cause blood clots to develop spontaneously. Normally, your blood begins to clot to prevent a massive loss of blood after an injury. In people with primary thrombocythemia, however, blood clots can form suddenly and for no apparent reason. Abnormal blood clotting can be dangerous.

What happens if your platelets are too high?

Thrombocytosis is a condition in which there is an excessive number of platelets in the blood. Platelets are blood cells in plasma that stop bleeding by sticking together to form a clot. Too many platelets can lead to certain conditions, including stroke, heart attack, or a clot in the blood vessels.

What infections cause thrombocytosis?

Essential thrombocythemia (ET) was the most common cause of primary thrombocytosis. Among secondary, non-infectious etiologies, tissue damage was the most common, followed by malignancy and iron-deficiency anemia. The most common infectious causes of thrombocytosis were soft-tissue, pulmonary and GI infections.

Can stress cause high platelets?

Stressful life events and anxiety usually cause an increase in platelet volume and activity through various mechanisms. Mean platelet volume (MPV), which is indicative of platelet size, is accepted as an indication of platelet activity.
