I-Coagulation INR ibizwa nangokuthi i-PT-INR ngokomtholampilo, i-PT isikhathi se-prothrombin, kanti i-INR iyisilinganiso esijwayelekile samazwe ngamazwe.I-PT-INR iyinto yokuhlola elabhorethri futhi ingesinye sezinkomba zokuhlola umsebenzi wokuhlangana kwegazi, onenani elibalulekile lereferensi ekusebenzeni komtholampilo.

Uhla olujwayelekile lwe-PT luyi-11s-15s kubantu abadala, kanye no-2s-3s lwezingane ezisanda kuzalwa.Ibanga elijwayelekile le-PT-INR kubantu abadala lingu-0.8-1.3.Uma kusetshenziswa izidakamizwa ze-anticoagulant, njengamaphilisi e-warfarin sodium, ububanzi be-PT-INR kunconywa ukuthi bulawuleke ku-2.0-3.0 ukuze kuzuzwe umphumela osebenzayo we-anticoagulant.Amaphilisi e-Warfarin sodium asetshenziswa kakhulu ama-anticoagulants omtholampilo ekwelapheni i-deep vein thrombosis noma isifo se-thrombotic esibangelwa i-atrial fibrillation, isifo se-valvular, i-pulmonary embolism, njll. I-PT-INR iyinkomba ebalulekile yokuhlola ukusebenza kwe-coagulation emzimbeni, futhi futhi isisekelo sokuthi odokotela balungise umthamo wamaphilisi e-warfarin sodium.Uma i-PT-INR iphezulu kakhulu, ikhombisa ingozi yokopha.Uma izinga le-PT-INR liphansi kakhulu, lingabonisa ubungozi bokuhlule kwegazi.

Lapho kuhlolwa i-PT-INR, ngokuvamile kuyadingeka ukuthatha igazi le-venous.Le ndlela ayinayo imfuneko ecacile yokuzila ukudla, futhi iziguli azidingi ukukhathalela ukuthi ziyadla noma cha.Ngemuva kokukhishwa kwegazi, kunconywa ukusebenzisa i-swab kakotini oyinyumba ukumisa ukopha, ukuze ugweme amazinga e-PT-INR eqile, ukuhlangana okungekuhle kuzodala imihuzuko engaphansi kwesikhumba.
