The Partial Thromboplastin Time (PTT).

J Thromb Haemost. 2013 Dec 18;

Authors: Blatt PM, White GC

The Partial Thromboplastin Time (PTT) was described in 1953 by Langdell, Wagner, and Brinkhous (1). The evolution and significance of the PTT was reviewed in JTH in 2003 in a historical sketch (2). Recent publications (3,4) have attributed the PTT development to Proctor and Rapaport (5). In fact, the kaolin-activated PTT of Proctor and Rapaport is a refinement of the original PTT test previously published by Langdell, et al. (1). This article is protected by copyright.
