<unk>  (or -paenia, or thrombopenia in short) is the presence of relatively few platelets in blood.
Generally speaking, a normal platelet count ranges from 150,000 and 450,000 per mm3. These limits, however, are determined by the 2.5th lower and upper percentile, and a deviation does not necessarily imply any form of disease. The number of platelets in a blood sample also decreases quickly with time and a low platelet count may be caused by a delay between sampling and analysis.
