O le taimi o le Prothrombin (PT) o se faʻailoga taua tele e faʻaalia ai le faʻaogaina o le ate, galuega faʻaagaga, faʻamaʻi maʻi ma faʻamaʻi.I le taimi nei, o le suʻesuʻeina o falemaʻi o mea faʻapitoa ua avea ma mea moni, ma o le a tuʻuina atu muamua ma sili atu faʻamatalaga saʻo nai lo le PT i le faʻamasinoina o le tulaga o le maʻi ate.

Fa'aaogāga fa'apitoa ole PT ile fa'ama'i ate:

Le falesuesue lipoti PT i auala e fa: prothrombintime activitypercentagePTA (prothrombin time ratio PTR) ma faava o malo tulaga masani INR.O fa'ailoga e fa 'ese'ese tau fa'aoga ile falema'i.

Ole aoga ole PT ile fa'ama'i ate: O le PT e fa'atatau ile maualuga ole coagulation factor IIvX fa'apipi'iina e le ate, ma o lana matafaioi ile fa'ama'i ate e taua tele.O le fua faatatau faaletonu o le PT i hepatitis matuitui sa 10% -15%, hepatitis faaumiumi sa 15% -51%, cirrhosis sa 71%, ma hepatitis ogaoga sa 90%.I le faʻataʻitaʻiga o faʻamaʻi pipisi o le hepatitis viral i le 2000, o le PTA o se tasi lea o faʻailoga o le faʻatulagaina o falemaʻi o tagata mamaʻi ma le hepatitis viral.Ma'i hepatitis viral tumau ma PTA malu> 70%, feololo 70% -60%, ogaoga 60% -40%;cirrhosis fa'atasi ai ma le tulaga tau totogi PTA>60% decompensated tulaga PTA<60%;hepatitis ogaoga PTA<40%" I le Child-Pugh fa'avasegaga, 1 mata mo PT fa'aumiumi o 1 ~ 4s, 2 points mo 4 ~ 6s, 3 points mo> 6s, fa'atasi ma isi fa'ailoga 4 (albumin, bilirubin, ascites, encephalopathy ), o le galuega o le ate o tagata mamaʻi e maua i le ate Faʻasao ua vaevaeina i ABC grades; MELD score (Model for end-stageliver disease), lea e fuafua ai le ogaoga o le faʻamaʻi i tagata mamaʻi e maua i le faʻamaʻi o le ate ma le faʻasologa o le totoina o le ate, le fua ole .8xloge[bilirubin(mg/dl)+11.2xloge(INR)+ 9.6xloge[creatinine (mg/dl]+6.4x (mafuaaga: biliary poʻo le ava malosi 0; isi 1), INR o se tasi o 3 faʻailoga.

DIC fa'ata'ita'iga mo fa'ama'i ate e aofia ai: PT fa'aumiumi mo le sili atu nai lo le 5s po'o le fa'agaoioia vaega o le thromboplastin taimi (APTT) mo le sili atu i le 10s, fa'ailoga VIII gaioiga <50% (mana'omia);PT ma platelet count e masani ona faʻaaogaina e iloilo ai le biopsy o le ate ma le taotoga O le maʻi toto o gasegase, e pei o platelets <50x10 ° / L, ma le faʻalauteleina o le PT e sili atu i le masani mo le 4s o faʻalavelave mo le biopsy o le ate ma le taotoga e aofia ai le totoina o le ate.E mafai ona iloa o le PT o loʻo i ai se sao taua i le suʻesuʻeina ma le togafitiga o tagata mamaʻi e maua i le ate.
