====== Bleeding time ======
 

Historically, [[bleeding time]] (BT) was used as the [[screening]] [[test]] for abnormalities of [[platelet function]]. Due to unreliability, many [[institution]]s have replaced the BT with the [[platelet function]] assay (PFA) using the PFA-100 (platelet function analyzer). There are limited studies confirming its use according to the International Society of Thrombosis and Hemostasis
