Prothrombin time (PT) and partial thromboplastin time (PTT) tests are commonly ordered for hospitalized patients. A significant reduction in laboratory workload and expense can be achieved if these tests are ordered appropriately. The likelihood that the patient will benefit from these tests is small.
凝血酶原时间（PT）和部分凝血活酶时间（PTT）检测常用于住院患者。如果这些检测的医嘱开具得当，可显著减少实验室工作量和费用。患者从这些检测中获益的可能性很小。
