what causes a blood to get to thin
What Is Thin Blood or Thrombocytopenia? Thrombocytopenia is also known as 'thin blood', and is characterized by a drop in the amount of platelets in the blood. Whereas the normal levels of platelets are around 150,000 to 450,000 per microlitre, most definitions of thrombocytopenia involve levels of 50,000 and below.
