D-dimer theem yuav yog nce siab nyob rau hauv ib qho kev kho mob uas txhaws daim ntawv. D-dimer theem tau nce siab hauv kev raug mob, kev phais tsis ntev los no, hemorrhage, qog noj ntshav, thiab sepsis. Ntau ntawm cov xwm txheej no cuam tshuam nrog kev pheej hmoo siab dua rau kev sib sib zog nqus venous thrombosis (DVT). D-dimer theem tseem nce siab hauv DVT txog li 7 hnub.

Koj puas muaj DVT thiab ib txwm D-dimer?

Neeg-yim ntawm 81 tus neeg mob uas muaj DVT muaj qhov qub D-dimer, piv nrog ob ntawm 56 tus neeg mob uas muaj DVT. Qhov rhiab heev rau DVT distal tsuas yog 65% piv nrog 96% rau DVT proximal; qhov kev kwv yees tsis zoo yog 84 thiab 99%, feem.

Dab tsi tuaj yeem ua rau D-dimer nce siab?

Tsis tas li ntawd, cov qib D-dimer siab tsis yog ib txwm tshwm sim los ntawm cov teeb meem txhaws. Lwm yam xwm txheej uas tuaj yeem ua rau D-dimer siab muaj xws li cev xeeb tub, kab mob plawv, thiab kev phais tsis ntev los no. Yog tias koj qhov D-dimer cov txiaj ntsig tsis zoo li qub, koj tus kws kho mob tej zaum yuav xaj ntau qhov kev ntsuam xyuas los kuaj mob.

D-dimer puas tuaj yeem dag siab?

Qhov tshwj xeeb feem ntau yog nyob nruab nrab ntawm 40% thiab 60%, ua rau siab tus nqi ntawm cov txiaj ntsig tsis tseeb. Ntau yam, uas tsis yog PE lossis cov hlab ntsha sib sib zog nqus (DVT), yog txuam nrog cov txiaj ntsig zoo D-dimer. Qee yam, xws li cov hnub nyoog siab, mob hnyav, thiab cev xeeb tub, tau piav qhia hauv cov ntaub ntawv kho mob.

Puas yog D-dimer ib txwm nce siab nrog PE?

Qib plasma ntawmD-dimer, cov khoom lag luam fibrin degradation (FDP), yog ze li ib txwm nce ntxiv thaum muaj mob ntsws embolism (PE). Li no, ib txwm D-dimer theem (hauv qab tus nqi txiav tawm ntawm 500 micrograms / L los ntawm enzyme-linked immunosorbent assay [ELISA]) tuaj yeem tso cai kom tsis suav nrog PE.
