Sheep were dosed with natural and synthetic anticoagulants to prolong prothrombin time (PT) in the one stage PT test. The stability of subsequent values of PT of up to 40 seconds was measured at various times over a 24 hour period in plasma and whole blood stored at 0, 20 and 30 degrees C, representing ideal to unsuitable conditions of sample preparation and storage. In contrast to cautions in the literature, the various treatments had little influence on PT. These findings should encourage the use of PT in field diagnosis and research in sheep by surmounting the tenet of the difficulty in effectively preserving blood samples for PT determinations.
给绵羊注射天然和合成抗凝剂，以延长一期凝血酶原时间（PT）测试中的凝血酶原时间。在0℃、20℃和30℃下储存的血浆和全血中，于24小时内的不同时间测量长达40秒的后续PT值稳定性，这些温度代表了样本制备和储存从理想到不合适的条件。与文献中的注意事项相反，各种处理对PT影响很小。这些发现应鼓励在绵羊的现场诊断和研究中使用PT，因为这克服了有效保存血样用于PT测定存在困难这一原则问题。
