Coagulation disgnostic e aofia ai le plasma prothrombin time (PT), activated partial prothrombin time (APTT), fibrinogen (FIB), thrombin time (TT), D-dimer (DD), International standardization Ratio (INR).

PT: E faʻaalia tele le tulaga o le faʻaogaina o le tino, lea e masani ona faʻaogaina le INR e mataʻituina ai vailaʻau faʻamaʻi.O le faʻaumiumi o loʻo faʻaalia i le congenital coagulation factor ⅡⅤⅦⅩ deficiency ma fibrinogen deficiency, ma le mauaina o le coagulation factor deficiency e masani lava ona vaaia i le vitamini K deficiency, maʻi ogaoga ate, hyperfibrinolysis, DIC, oral anticoagulants, ma isi;fa'apuupuu e va'aia i le toto hypercoagulable tulaga ma thrombosis ma'i, ma isi.

APTT: E faʻaalia tele le tulaga o le faiga o le coagulation, ma e masani ona faʻaaogaina e mataʻituina ai le vailaʻau o le heparin.Fa'ateleina i le plasma factor VIII, fa'ailoga IX ma fa'ale XI fa'aititia le maualuga: pei ole hemophilia A, hemophilia B ma le fa'aletonu XI;faʻaititia i le hypercoagulable state: e pei o le faʻauluina o mea procoagulant i totonu o le toto ma faʻateleina le gaioiga o mea faʻapipiʻi, ma isi.

FIB: e masani ona atagia ai mea o loʻo i totonu o le fibrinogen.Faʻateleina i le faʻalavelave faʻafuaseʻi o le myocardial ma faʻaitiitia i le DIC consumptive hypocoagulable dissolution period, fibrinolysis muamua, hepatitis ogaoga, ma le ate cirrhosis.

TT: E atagia mai ai le taimi na liua ai le fibrinogen i le fibrin.O le faʻaopoopoga na vaʻaia i le tulaga o le hyperfibrinolysis o le DIC, faʻatasi ai ma le maualalo (leai) fibrinogenemia, hemoglobinemia faʻaletonu, ma le faʻateleina o oloa faʻaleagaina (fibrinogen) (FDP) i le toto;o le fa'aititia e leai se taua fa'apitoa.

INR: O le International Normalized Ratio (INR) e fuafua mai le taimi o le prothrombin (PT) ma le International Sensitivity Index (ISI) o le suʻega suʻega.O le faʻaaogaina o le INR e faʻatusatusa ai le PT i fale suʻesuʻe eseese ma faʻalavelave eseese e faʻatusatusa, lea e faʻafaigofie ai le tuʻufaʻatasia o tulaga o vailaʻau.

O le tāua tele o le suʻesuʻeina o le toto mo tagata gasegase, o le siakiina lea pe o iai se faʻafitauli i le toto, ina ia mafai ai e fomaʻi ona malamalama lelei i le tulaga o le maʻi i le taimi, ma faigofie ai mo fomaʻi ona ave saʻo vailaʻau ma togafitiga.O le aso sili mo le tagata maʻi e fai ai suʻega e lima o le coagulation o loʻo i luga o le manava gaogao, ina ia sili atu le saʻo o taunuuga o le suʻega.A maeʻa le suʻega, e tatau i le tagata maʻi ona faʻaalia iuga o suʻega i le fomaʻi e suʻe ai faʻafitauli o le toto ma puipuia ai le tele o faʻalavelave.
