I te wa e pa ana te mate o te toto, ka taea e koe te haere ki te hohipera ki te kimi i te plasma prothrombin.Ko nga waahanga motuhake o te whakamatautau mahi coagulation e whai ake nei:

1. Te kitenga o te plasma prothrombin: Ko te uara noa o te kitenga plasma prothrombin he 11-13 hēkona.Mena ka kitea te roa o te wa coagulation, e tohu ana i te kino o te ate, te mate ate ate, te ate cirrhosis, te jaundice aukati me etahi atu mate;Mena ka poto te wa o te coagulation, tera pea he mate thrombotic.

2. Whakahaerehia te tauwehenga o te ao: Koinei te tauwehenga whakahaere i waenga i te wa prothrombin o te manawanui me te wa prothrombin noa.Ko te awhe noa o tenei tau ko te 0.9~1.1.Mena he rereke mai i te uara noa, e tohu ana kua puta te mahi coagulation Ka nui ake te aputa, ka nui ake te raru.

3. Te rapunga o te wa thromboplastin wahanga whakahohe: He whakamatautau tenei ki te kite i nga ahuatanga o te coagulation endogenous.Ko te uara noa he 24 ki te 36 hēkona.Mena ka roa te wa whakakoi o te manawanui, e tohu ana tera pea ka raru te mate o te mate fibrinogen.Ka pa ki te mate ate, te jaundice arai me etahi atu mate, ka mate pea nga whanau hou i te whakaheke toto;Mena he poto ake i te waa noa, e tohu ana tera pea ka pa te mate o te manawanui ki te mate myocardial infarction, te whiu ischemic, te thrombosis venous me etahi atu mate.

4. Te kitenga o te fibrinogen: ko te awhe noa o tenei uara kei waenganui i te 2 me te 4. Mena ka piki ake te fibrinogen, ka tohu he mate whakapeka te manawanui, ka pangia pea e te atherosclerosis, te mate huka, te uremia me etahi atu mate;Ki te heke iho tenei uara, tera pea ka nui te mate hepatitis, ate cirrhosis me etahi atu mate.

5. Te whakatau i te wa thrombin;ko te awhe noa o tenei uara ko te 16 ~ 18, i te mea he roa ake i te uara noa ma te neke atu i te 3, he rereke, e tohu ana i te mate ate, te mate whatukuhu me etahi atu mate.Mena ka poto te wa thrombin, tera pea he katote konupūmā kei roto i te tauira toto.

6. Te whakatau i te D dimer: Ko te awhe noa o tenei uara ko 0.1~0.5.Mena ka kitea he nui te pikinga o te uara i te wa o te whakamatautau, tera pea he mate ngakau me te cerebrovascular, pulmonary embolism, me nga pukupuku kino.
