Thrombocytopenia refers to a low platelet count in the blood. A platelet is the part of blood that helps you stops bleeding when you get cut. They are made in the bone marrow like other blood cells. A low platelet count, thrombocytopenia, can be caused by chemotherapy, infection, medications, viruses or other factors. If the platelet count is low, a person is at a greater risk for bleeding.

Guidelines for platelet count are:

>150,000 - Normal Count
100,000 - 150,000 - Adequate
50,000 - 100,000 - Minimal risk for bleeding due to low platelets
20,000 - 50,000 - Some increased risk for bleeding due to low platelets with trauma or sugery. Treatment may be given. 
<20,000 - At higher risk for bleeding due to low platelets. Treatment may be given.
