PT txhais tau tias lub sijhawm prothrombin hauv tshuaj, thiab APTT txhais tau tias lub sijhawm ua haujlwm ib nrab thromboplastin hauv tshuaj. Lub luag haujlwm coagulation ntshav ntawm tib neeg lub cev yog qhov tseem ceeb heev. Yog tias lub luag haujlwm coagulation ntshav tsis zoo, nws yuav ua rau thrombosis lossis los ntshav, uas yuav ua rau muaj kev phom sij rau lub neej ntawm tus neeg mob. Kev saib xyuas kev kho mob ntawm PT thiab APTT tus nqi tuaj yeem siv ua tus qauv rau kev siv qee cov tshuaj anticoagulant hauv kev kho mob. Yog tias cov nqi ntsuas siab dhau, nws txhais tau tias cov tshuaj anticoagulant yuav tsum tau txo qis, txwv tsis pub los ntshav yuav yooj yim tshwm sim.

1. Lub sijhawm Prothrombin (PT): Nws yog ib qho ntawm cov cim qhia txog kev coagulation ntawm tib neeg cov ntshav. Nws muaj lub ntsiab lus ntau dua los ncua lub sijhawm ntau dua 3 vib nas this hauv kev kho mob, uas tuaj yeem cuam tshuam seb qhov kev ua haujlwm coagulation sab nraud puas yog qhov ib txwm muaj. Kev ncua sijhawm feem ntau pom hauv cov neeg mob congenital coagulation Factor deficiency, cirrhosis hnyav, mob siab tsis ua haujlwm thiab lwm yam kab mob. Tsis tas li ntawd, kev noj tshuaj heparin thiab warfarin ntau dhau kuj tseem yuav ua rau PT ntev;

2. Lub sijhawm ua haujlwm ib nrab thromboplastin (APTT): Nws yog qhov ntsuas uas qhia txog kev ua haujlwm ntawm cov ntshav coagulation hauv kev kho mob. Kev ncua sijhawm ntawm APTT feem ntau pom muaj nyob rau hauv cov neeg mob uas muaj teeb meem coagulation factor los ntawm kev yug los lossis tau txais, xws li hemophilia thiab systemic lupus erythematosus. Yog tias cov tshuaj anticoagulant siv vim yog thrombosis tsis zoo, nws kuj tseem yuav ua rau APTT ntev dua. Yog tias tus nqi ntsuas qis, xav tias tus neeg mob nyob rau hauv lub xeev hypercoagulable, xws li cov leeg ntshav tob thrombosis.

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