A capillary prothrombin time method was described using the Australasian Reference Thromboplastin (A.R.T.). The method was used for the control of oral anticoagulant therapy in 59 patients on 225 occasions and was found to be reliable and convenient. The capillary prothrombin ratio could be correlated with the conventional plasma prothrombin ratio.
