Feem ntau cov ntshav tsis khov txawm tias nws zoo lossis phem. Cov ntshav khov muaj lub sijhawm ib txwm muaj. Yog tias nws ceev dhau lossis qeeb dhau, nws yuav ua rau lub cev puas tsuaj.

Cov ntshav coagulation yuav nyob rau hauv ib qho ntau yam, yog li ntawd kom tsis txhob ua rau los ntshav thiab thrombus tsim nyob rau hauv tib neeg lub cev. Yog tias cov ntshav coagulation sai dhau, nws feem ntau qhia tau tias tib neeg lub cev nyob rau hauv lub xeev hypercoagulable, thiab cov kab mob plawv thiab cerebrovascular feem ntau tshwm sim, xws li cerebral infarction thiab Myocardial infarction, qis extremity venous thrombosis thiab lwm yam kab mob. Yog tias tus neeg mob cov ntshav coagulates qeeb dhau, nws yuav muaj teeb meem coagulation, feem ntau muaj cov kab mob los ntshav, xws li hemophilia, thiab nyob rau hauv cov xwm txheej hnyav, nws yuav tawm hauv cov pob qij txha deformations thiab lwm yam tsis zoo tshwm sim.

Kev ua haujlwm thrombin zoo qhia tau tias cov platelets ua haujlwm zoo thiab noj qab nyob zoo heev. Kev coagulation txhais tau hais tias cov ntshav hloov los ntawm lub xeev ntws mus rau lub xeev gel, thiab nws lub ntsiab lus yog cov txheej txheem ntawm kev hloov cov fibrinogen uas yaj tau mus rau hauv cov fibrinogen uas tsis yaj hauv cov ntshav. Hauv kev nkag siab nqaim, thaum cov hlab ntsha raug puas tsuaj, lub cev tsim cov coagulation factors, uas tau qhib kom ua rau tsim thrombin, uas thaum kawg hloov fibrinogen mus rau hauv fibrin, yog li txhawb kev coagulation ntshav. Kev coagulation feem ntau kuj suav nrog cov platelet ua haujlwm.

Kev txiav txim seb qhov coagulation zoo lossis tsis zoo yog feem ntau los ntawm kev los ntshav thiab kev kuaj hauv chaw kuaj mob. Kev ua haujlwm tsis zoo ntawm cov ntshav coagulation yog hais txog teeb meem nrog cov yam ntxwv coagulation, txo qis lossis ua haujlwm tsis zoo, thiab ntau yam tsos mob ntawm kev los ntshav. Kev los ntshav uas tshwm sim los ntawm tus kheej tuaj yeem tshwm sim, thiab purpura, ecchymosis, epistaxis, cov pos hniav los ntshav, thiab hematuria tuaj yeem pom ntawm daim tawv nqaij thiab cov ntaub so ntswg. Tom qab raug mob lossis phais, qhov ntau ntawm kev los ntshav nce ntxiv thiab lub sijhawm los ntshav tuaj yeem ntev dua. Los ntawm kev kuaj pom lub sijhawm prothrombin, lub sijhawm prothrombin ua haujlwm ib nrab thiab lwm yam khoom, nws pom tias kev ua haujlwm coagulation tsis zoo, thiab qhov ua rau mob yuav tsum tau piav qhia meej.
