ʻO ka manawa Prothrombin (PT) kahi hōʻailona koʻikoʻi e hōʻike i ka hana o ka ate synthesis, ka hana mālama, ka nui o ka maʻi a me ka prognosis.I kēia manawa, ua lilo ka ʻike lapaʻau o nā kumu coagulation i mea ʻoiaʻiʻo, a hāʻawi ia i ka ʻike ma mua a ʻoi aku ka pololei ma mua o ka PT i ka hoʻoholo ʻana i ke ʻano o ka maʻi ate.
ʻO ka noi ʻana o ka PT i ka maʻi ate:
Hōʻike ka hale hana i ka PT ma nā ʻano ʻehā: prothrombintime activitypercentagePTA (prothrombin time ratio PTR) a me INR normalized ratio honua.Loaʻa i nā ʻano ʻehā nā waiwai hoʻohana lapaʻau like ʻole.
