Thrombin lub sij hawm (TT) thiab prothrombin lub sij hawm (PT) feem ntau yog siv coagulation muaj nuj nqi nrhiav kom tau qhov taw qhia, qhov sib txawv ntawm ob qhov lus dag nyob rau hauv kev tshawb pom ntawm txawv coagulation yam.

Thrombin lub sij hawm (TT) yog ib qho qhia txog lub sij hawm uas yuav tsum tau kuaj xyuas cov kev hloov ntawm plasma prothrombin rau hauv thrombin.Nws yog tsuas yog siv los ntsuas qhov ua haujlwm ntawm fibrinogen thiab coagulation yam I, II, V, VIII, X thiab XIII hauv plasma.Thaum lub sijhawm kuaj pom, qee qhov ntawm cov nqaij mos prothrombin thiab calcium ions tau ntxiv los hloov cov prothrombin hauv cov ntshav mus rau thrombin, thiab lub sijhawm hloov pauv yog ntsuas, uas yog tus nqi TT.

Prothrombin lub sij hawm (PT) yog qhov ntsuas los ntsuas qhov ua haujlwm ntawm cov ntshav coagulation yam sab nraud ntawm cov ntshav coagulation system.Thaum lub sijhawm kuaj pom, qee qhov nyiaj ntawm coagulation yam muaj pes tsawg leeg (xws li coagulation yam II, V, VII, X thiab fibrinogen) yog ntxiv los qhib lub coagulation system, thiab lub sij hawm rau kev tsim cov ntshav yog ntsuas, uas yog tus nqi PT.Tus nqi PT qhia txog cov xwm txheej ntawm coagulation yam ua haujlwm sab nraum coagulation system.

Nws yuav tsum raug sau tseg tias ob qho tib si TT thiab PT qhov tseem ceeb feem ntau siv cov ntsuas los ntsuas kev ua haujlwm ntawm coagulation, tab sis ob qho tib si tsis tuaj yeem hloov ib leeg, thiab cov ntsuas ntsuas tsim nyog yuav tsum raug xaiv raws li cov xwm txheej tshwj xeeb.Nyob rau tib lub sijhawm, nws yuav tsum raug sau tseg tias qhov sib txawv ntawm cov txheej txheem tshawb pom thiab cov tshuaj reagents tuaj yeem cuam tshuam qhov tseeb ntawm cov txiaj ntsig, thiab yuav tsum tau them nyiaj rau cov qauv kev ua haujlwm hauv kev kho mob.
