PT txhais tau hais tias lub sijhawm prothrombin hauv cov tshuaj, thiab APTT txhais tau hais tias lub sijhawm ua haujlwm ib nrab ntawm thromboplastin hauv cov tshuaj.Cov ntshav coagulation ua haujlwm ntawm tib neeg lub cev tseem ceeb heev.Yog tias cov ntshav coagulation ua haujlwm tsis zoo, nws tuaj yeem ua rau thrombosis lossis los ntshav, uas tuaj yeem ua rau mob hnyav rau tus neeg mob lub neej.Kev soj ntsuam xyuas ntawm PT thiab APTT qhov tseem ceeb tuaj yeem siv los ua tus qauv rau kev siv qee cov tshuaj tiv thaiv coagulant hauv kev kho mob.Yog tias qhov ntsuas qhov ntsuas siab dhau lawm, nws txhais tau hais tias koob tshuaj anticoagulant yuav tsum tau txo, txwv tsis pub los ntshav yuav yooj yim tshwm sim.

1. Prothrombin lub sij hawm (PT): Nws yog ib qho ntawm cov cim qhia ntau dua ntawm tib neeg cov ntshav coagulation system.Nws yog qhov muaj txiaj ntsig zoo kom ncua sij hawm ntev dua 3 vib nas this hauv kev kho mob, uas tuaj yeem cuam tshuam seb qhov exogenous coagulation muaj nuj nqi yog qhov qub.Kev ncua ntev yog pom nyob rau hauv congenital coagulation Factor deficiency, mob cirrhosis hnyav, siab tsis ua hauj lwm thiab lwm yam kab mob.Tsis tas li ntawd, kev siv tshuaj ntau dhau ntawm heparin thiab warfarin kuj tseem tuaj yeem ua rau PT ntev;

2. Ua kom ib nrab thromboplastin lub sij hawm (APTT): Nws yog qhov tseem ceeb tshaj plaws uas qhia txog cov ntshav coagulation endogenous hauv kev kho mob.Qhov kev ncua ntev ntawm APTT feem ntau yog pom nyob rau hauv congenital los yog tau txais coagulation yam tsis txaus, xws li hemophilia thiab kab mob lupus erythematosus.Yog tias koob tshuaj anticoagulant siv vim thrombosis yog qhov txawv txav, nws tseem yuav ua rau lub sijhawm ntev ntawm APTT.Yog tias ntsuas tus nqi qis, xav txog tus neeg mob nyob rau hauv lub xeev hypercoagulable, xws li cov hlab ntsha sib sib zog nqus thrombosis.

Yog tias koj xav paub seb koj tus PT thiab APTT puas zoo li qub, koj yuav tsum tau qhia meej txog lawv qhov qub.Qhov ntau npaum li cas ntawm PT yog 11-14 vib nas this, thiab qhov ntau ntawm APTT yog 27-45 vib nas this.PT ncua ntev tshaj 3 vib nas this muaj qhov tseem ceeb ntawm kev kho mob ntau dua, thiab APTT ncua ntev dua 10 vib nas this muaj qhov tseem ceeb hauv kev kho mob.
