Cov Khoom Siv Ua Haujlwm Ib Feem Thromboplastin Sijhawm (APTT)

Kev ntsuas APTT yog qhov feem ntau siv tshuaj ntsuam xyuas qhov ntsuas ntsuas ntsuas kom pom cov kev ua haujlwm coagulation ntawm endogenous coagulation system.Nws yog siv los txheeb xyuas endogenous coagulation yam tsis xws luag thiab lwm yam inhibitors thiab tshuaj ntsuam qhov tshwm sim ntawm activated protein C kuj.Nws muaj ntau yam kev siv nyob rau hauv cov nqe lus ntawm kev tshuaj xyuas, kev saib xyuas ntawm heparin txoj kev kho, kev kuaj mob ntxov ntawm disseminated intravascular coagulation (DIC), thiab kev kuaj ua ntej.

Clinical tseem ceeb:

APTT yog ib qho kev ntsuas kev ua haujlwm coagulation uas qhia txog txoj hauv kev endogenous coagulation, tshwj xeeb tshaj yog cov kev ua haujlwm ntawm coagulation yam hauv thawj theem.Nws yog dav siv los tshuaj xyuas thiab txiav txim siab qhov tsis xws ntawm coagulation yam hauv txoj hauv kev endogenous, xws li yam Ⅺ , Ⅷ , Ⅸ , nws kuj tuaj yeem siv rau kev tshuaj ntsuam xyuas ua ntej ntawm cov kab mob los ntshav thiab kuaj xyuas ntawm heparin anticoagulation therapy.

1. Ntev ntev: tuaj yeem pom hauv hemophilia A, hemophilia B, kab mob siab, plab hnyuv sterilization syndrome, qhov ncauj anticoagulants, diffuse intravascular coagulation, mob hemophilia;FXI, FXII deficiency;ntshav Anticoagulant tshuaj (coagulation yam inhibitors, lupus anticoagulants, warfarin los yog heparin) nce;ntau cov ntshav khaws cia tau hloov pauv.

2. Shorten: Nws tuaj yeem pom hauv lub xeev hypercoagulable, kab mob thromboembolic, thiab lwm yam.

Kev siv ntau yam ntawm tus nqi ib txwm muaj

Qhov ib txwm siv tus nqi ntawm lub sijhawm ua haujlwm ib nrab thromboplastin (APTT): 27-45 vib nas this.

Cov kev ceev faj

1. Tsis txhob kuaj ntshav hemolysis.Cov qauv hemolyzed muaj phospholipids tso tawm los ntawm kev tawg ntawm cov qog ntshav liab uas paub tab, uas ua rau APTT qis dua qhov ntsuas tus nqi ntawm cov qauv uas tsis yog hemolyzed.

2. Cov neeg mob yuav tsum tsis txhob koom nrog kev ua ub ua no hauv 30 feeb ua ntej tau txais cov ntshav kuaj.

3. Tom qab khaws cov ntshav, maj mam muab cov hlab ntshav ntsuas uas muaj cov ntshav coj los ua piv txwv txog cov ntshav nrog anticoagulant hauv kev sim raj.

4. Cov qauv ntshav yuav tsum raug xa mus kuaj sai li sai tau.
