Cov Khoom Siv Thrombin Time (TT)

TT yog lub sijhawm ntshav txhaws tom qab ntxiv cov thrombin txheem rau hauv cov ntshav. Hauv txoj kev coagulation, cov thrombin tsim tawm hloov fibrinogen mus rau hauv fibrin, uas tuaj yeem cuam tshuam los ntawm TT. Vim tias fibrin (proto) degradation products (FDP) tuaj yeem ntev TT, qee tus neeg siv TT ua kev kuaj mob rau fibrinolytic system.

Qhov tseem ceeb ntawm kev kho mob:

(1) TT ntev dua (ntau dua 3s ntau dua li kev tswj hwm ib txwm) heparin thiab heparinoid cov tshuaj nce ntxiv, xws li lupus erythematosus, kab mob siab, kab mob raum, thiab lwm yam. Qis (tsis muaj) fibrinogenemia, fibrinogenemia txawv txav.

(2) FDP nce ntxiv: xws li DIC, thawj fibrinolysis thiab lwm yam.

Lub sijhawm thrombin ntev (TT) pom tau tias muaj cov fibrinogen hauv cov ntshav tsawg dua lossis cov qauv tsis zoo; kev siv tshuaj heparin hauv kev kho mob, lossis cov tshuaj heparin zoo li anticoagulants ntau dua hauv kab mob siab, kab mob raum thiab kab mob lupus erythematosus; ua haujlwm ntau dhau ntawm lub cev fibrinolytic. Lub sijhawm thrombin luv dua pom tau tias muaj cov calcium ions hauv cov ntshav, lossis cov ntshav muaj kua qaub, thiab lwm yam.

Lub sijhawm thrombin (TT) yog qhov kev xav ntawm cov tshuaj anticoagulant hauv lub cev, yog li nws qhov ntev qhia txog hyperfibrinolysis. Qhov ntsuas yog lub sijhawm tsim ntawm fibrin tom qab ntxiv cov qauv thrombin, yog li ntawd hauv cov kab mob fibrinogen qis (tsis muaj), DIC thiab Ntev nyob rau hauv qhov muaj cov tshuaj heparinoid (xws li heparin kho, SLE thiab kab mob siab, thiab lwm yam). Kev luv ntawm TT tsis muaj qhov tseem ceeb hauv kev kho mob.

Qhov Ntau Yam Ib Txwm Muaj:

Tus nqi ib txwm yog 16 ~ 18 vib nas this. Tshaj qhov kev tswj hwm ib txwm rau ntau tshaj 3 vib nas this yog qhov tsis zoo.

Lus Cim:

(1) Plasma yuav tsum tsis pub tshaj 3 teev ntawm chav sov.

(2) Disodium edetate thiab heparin yuav tsum tsis txhob siv ua anticoagulants.

(3) Thaum kawg ntawm kev sim, txoj kev kuaj lub raj mis yog raws li kev pib coagulation thaum muaj turbidity tshwm sim; txoj kev tais iav yog raws li lub peev xwm los ua rau cov fibrin filaments

Cov kab mob cuam tshuam:

Kab mob Lupus erythematosus
