Thrombocyte is the medical term for platelet. Thrombocytopenia means a lower
platelet count in the blood compared to the normal range. Thrombocytosis refers
to a greater number of platelets compared to the normal range.
Platelets are important elements in the blood that are important for blood
coagulation (clotting
and prevention of bleeding). The normal platelet count ranges between 150,000
and 450,000 per microliter (one-millionth of a liter).
Although the number of platelets is decreased, their function may remain intact
in most cases of thrombocytopenia.
All blood cells (white cells, red cells, and
platelets) are made in the bone marrow. Platelets are derived from larger cells in the bone marrow called
megakaryocytes. Fragments of megakaryocytes are platelets, which are released
into the bloodstream. Only about 2/3 of platelets released into the blood stream
circulate in the blood, and the remaining 1/3 is typically captured by the
spleen. The life cycle of platelets is usually about 7-10 days; therefore, the
old ones are continuously being replaced by new ones.
