In 34 patients undergoing anticoagulant therapy with warfarin a close relationship has been observed between the logarithm of the 'Thrombotest' response to a loading dose (10 mg/day for three days) and the maintenance dose required to achieve an anticoagulant response of 8-12% (thrombo-test). This relationship appears to be close enough to enable maintenance dosages to be predicted.
