The platelet count is part of a routine coagulation profile or work-up for clotting abnormalities. It is also useful in the assessment of bleeding disorders occurind due to thrombocytopenia, uremia, liver disease or malignancies, and for monitoring the course of disease associated with bone marrow failure<sup>1</sup>.

===Buccal Mucosal Bleeding Time===
The buccal mucosal bleeding time is a simple test that gives a rapid assessment of platelet function, providing platelet numbers are normal. If platelet numbers are below 50x10<sup>9</sup>l, this test should not be performed since bleeding may not be easily stopped.
When a small slit is made in the skin, the hemostatic mechanisms necessary for coagulation are activated. Without the aid of external pressure, bleeding usually stops within 7 to 9 minutes.
