Ua kapa ʻia ʻo Coagulation INR ʻo PT-INR ma ke kino, ʻo PT ka manawa prothrombin, a ʻo INR ka pae honua maʻamau.ʻO ka PT-INR kahi mea hōʻike hoʻokolohua a me kekahi o nā hōʻailona no ka hoʻāʻo ʻana i ka hana coagulation koko, he waiwai koʻikoʻi koʻikoʻi i ka hana lapaʻau.

ʻO ka laulā maʻamau o PT he 11s-15s no nā mākua, a he 2s-3s no nā keiki hānau hou.ʻO ka laulā maʻamau o PT-INR no nā mākua he 0.8-1.3.Inā hoʻohana ʻia nā lāʻau anticoagulant, e like me ka warfarin sodium tablets, ua ʻōlelo ʻia ka laulā o PT-INR e hoʻomalu ʻia ma 2.0-3.0 e hoʻokō i kahi hopena anticoagulant maikaʻi.Hoʻohana mau ʻia nā papa pāpaʻi sodium Warfarin i nā anticoagulants hauʻoli no ka mālama ʻana i ka thrombosis vein hohonu a i ʻole ka maʻi thrombotic i hoʻokumu ʻia e ka fibrillation atrial, maʻi valvular, pulmonary embolism, etc. ʻO ke kumu hoʻi no nā kauka e hoʻoponopono i ka nui o nā papa sodium warfarin.Inā kiʻekiʻe loa ka PT-INR, hōʻike ia i ka piʻi ʻana o ke koko.Inā haʻahaʻa loa ka pae PT-INR, hōʻike paha ia i ka pilikia o ke koko koko.

I ka hoʻāʻo ʻana i ka PT-INR, pono e lawe i ke koko venous.ʻAʻole pono kēia ʻano hoʻokē ʻai, a ʻaʻole pono nā mea maʻi e mālama inā hiki iā lākou ke ʻai a ʻaʻole paha.Ma hope o ka huki ʻana o ke koko, ʻōlelo ʻia e hoʻohana i kahi pulupulu sterile e hoʻōki i ke koko, i mea e pale aku ai i ka nui o nā pae PT-INR, ʻo ka coagulation maikaʻi ʻole e hoʻoulu i ka ʻeha subcutaneous.
