The Thromboplastin Generation Test

Abstract

Collection of Blood.-Venous blood is collected from a normal subject and the patient under investi- gation. Part of each sample is citrated by adding 1 part of 3.8% sodium citrate to 9 parts of blood. The plasma is separated after centrifuging at 2,000 r.p.m. for 15 minutes. Five millilitres of blood will suffice for the thromboplastin-generation test.
