Is it possible to have a prolonged bleeding time but a normal platelet count?

Abnormalities of platelet function can result in defective hemostasis and a prolonged bleeding time in spite of a normal platelet count.

How does aspirin affect the bleeding time?

Aspirin influences the bleeding time, presumably through the inhibition of prostaglandin biosynthesis and the resultant platelet secretion reaction. This can be measured by prolongation of the bleeding time and changes in platelet function results.

What is the normal range of BT and CT?
