Ko ngā tohu mō te toto totoka ko te wā prothrombin plasma (PT), te wā prothrombin wāhanga whakahohe (APTT), te fibrinogen (FIB), te wā thrombin (TT), te D-dimer (DD), me te ōwehenga paerewa ā-ao (INR).

PT: E whakaata ana i te āhua o te pūnaha toto toto o waho, ā, ko te INR te nuinga o te wā e whakamahia ana hei aroturuki i ngā rongoā toto toto ā-waha. Ka kitea te roa o te wā i roto i te ngoikore o te take toto toto whānau ⅡⅤⅦⅩ me te ngoikore o te fibrinogen, ā, ko te ngoikore o te take toto toto kua whiwhihia ka kitea i roto i te ngoikore o te huaora K, te mate ate kino, te hyperfibrinolysis, te DIC, ngā rongoā toto toto toto, me ētahi atu; ka kitea te poto i roto i te āhua toto toto totoka me te mate thrombosis, me ētahi atu.

APTT: E whakaata ana i te āhua o te pūnaha toto toto taketake, ā, e whakamahia ana hei aroturuki i te horopeta o te heparin. Ka piki ake te taumata o te matū toto VIII, te matū toto IX me te matū toto XI, ka heke iho: pērā i te hemophilia A, te hemophilia B me te koretake o te matū toto XI; ka heke iho i te āhua toto totoka nui: pērā i te urunga o ngā matū procoagulant ki roto i te toto me te pikinga o te mahi a ngā matū totoka, me ētahi atu.

FIB: e whakaata ana i te nui o te fibrinogen. Ka piki ake i te infarction myocardial acute, ka heke iho i te wā memeha hypocoagulable DIC consumptive, te fibrinolysis tuatahi, te hepatitis kino, me te cirrhosis ate.

TT: E whakaata ana i te wā e hurihia ai te fibrinogen hei fibrin. I kitea te pikinga i te wāhanga hyperfibrinolysis o te DIC, me te iti (kāore) o te fibrinogenemia, te hemoglobinemia rerekē, me te pikinga o ngā hua whakararu fibrin (fibrinogen) (FDP) i roto i te toto; kāore he hiranga haumanu o te hekenga.

INR: Ka tatauhia te Ōwehenga Whakaōrite o te Ao (INR) mai i te wā prothrombin (PT) me te Taurangi Aromātai o te Ao (ISI) o te matū whakamātautau. Mā te whakamahinga o te INR ka taea te whakataurite i te PT i inehia e ngā taiwhanga rerekē me ngā matū rerekē, ā, ka āwhina i te whakakotahitanga o ngā paerewa rongoā.

Ko te hiranga matua o te whakamātautau toto toto mō ngā tūroro he tirotiro mēnā he raruraru kei roto i te toto, kia taea ai e ngā tākuta te mārama ki te āhua o te tūroro i te wā tika, ā, he watea hoki mō ngā tākuta te tango i ngā rongoā me ngā maimoatanga tika. Ko te rā pai mō te tūroro ki te mahi i ngā whakamātautau toto toto toto e rima ko te wā e takoto kau ana te puku, kia tika ake ai ngā hua o te whakamātautau. I muri i te whakamātautau, me whakaatu e te tūroro ngā hua o te whakamātautau ki te tākuta kia kitea ai ngā raruraru o te toto, kia āraihia ai hoki ngā aituā maha.
