Muaj 9 hom tshuab nqus tsevcov hlab ntshav, uas yog qhov txawv ntawm cov xim ntawm lub kaus mom.
1. Common Serum Tube Red Cap
Lub raj xa dej tsis muaj cov tshuaj ntxiv, tsis muaj cov tshuaj tiv thaiv coagulant lossis procoagulant cov khoom xyaw, tsuas yog lub tshuab nqus tsev.Nws yog siv rau niaj hnub serum biochemistry, ntshav bank thiab serology hais txog kev kuaj, ntau yam biochemical thiab immunological kuaj, xws li syphilis, kab mob siab B kom muaj nuj nqis, thiab lwm yam. Nws tsis tas yuav tsum tau shaken tom qab nqus ntshav.Hom kev npaj cov qauv yog cov ntshav.Tom qab cov ntshav tau kos, nws muab tso rau hauv ib da dej ntawm 37 ° C rau ntau tshaj 30 feeb, centrifuged, thiab cov ntshav siab yog siv rau tom qab siv.
2. Ceev Ncua Tube Txiv kab ntxwv Cap
Muaj cov coagulant nyob rau hauv cov ntshav sau raj kom ceev cov txheej txheem coagulation.Cov hlab ntsha sai sai tuaj yeem coagulate cov ntshav sau hauv 5 feeb.Nws yog qhov tsim nyog rau kev kuaj ntshav thaum muaj xwm txheej ceev.Nws yog feem ntau siv coagulation xeem raj rau txhua hnub biochemistry, kev tiv thaiv kab mob, ntshav, tshuaj hormones, thiab lwm yam. Tom qab cov ntshav tau kos, invert thiab sib tov 5-8 zaug.Thaum qhov kub thiab txias qis, nws tuaj yeem muab tso rau hauv 37 ° C dej da dej rau 10-20min, thiab cov ntshav qab zib tuaj yeem centrifuged rau tom qab siv.
3. Lub hau kub ntawm lub inert sib cais gel accelerator raj
Inert separating gel thiab coagulant ntxiv rau hauv cov hlab ntshav.Cov qauv yog ruaj khov rau 48 teev tom qab centrifugation.Procoagulants tuaj yeem qhib lub coagulation mechanism sai sai thiab ua kom cov txheej txheem coagulation.Hom qauv npaj yog cov ntshav, uas yog tsim rau thaum muaj xwm txheej ceev biochemical kuaj thiab tshuaj pharmacokinetic.Tom qab sau, invert thiab sib tov 5-8 zaug, sawv ntsug rau 20-30 feeb, thiab centrifuge tus supernatant rau tom qab siv.
4. Sodium citrate ESR test tube dub cap
Qhov concentration ntawm sodium citrate xav tau rau kev kuaj ESR yog 3.2% (sib npaug rau 0.109mol / L), thiab qhov piv ntawm cov tshuaj tiv thaiv rau cov ntshav yog 1: 4.Muaj 0.4 mL ntawm 3.8% sodium citrate, thiab nqus ntshav mus rau 2.0 mL.Qhov no yog ib lub raj tshwj xeeb rau erythrocyte sedimentation tus nqi.Cov qauv qauv yog plasma, uas haum rau erythrocyte sedimentation tus nqi.Tam sim ntawd tom qab cov ntshav kos, invert thiab sib tov 5-8 zaug.Co zoo ua ntej siv.Qhov sib txawv ntawm nws thiab lub raj rau kev kuaj coagulation yog qhov sib txawv ntawm qhov concentration ntawm cov tshuaj tiv thaiv coagulant thiab qhov piv ntawm cov ntshav, uas yuav tsum tsis txhob tsis meej pem.
5. Sodium citrate coagulation kuaj raj lub teeb xiav cap
Sodium citrate feem ntau ua raws li cov tshuaj tiv thaiv coagulant los ntawm chelating calcium ions hauv cov ntshav kuaj.Lub anticoagulant concentration pom zoo los ntawm National Committee rau Standardization ntawm Clinical Laboratories yog 3.2% los yog 3.8% (sib npaug rau 0.109mol / L los yog 0.129mol / L), thiab qhov piv ntawm anticoagulant rau ntshav yog 1: 9.Lub tshuab nqus tsev sau cov ntshav muaj li 0.2 mL ntawm 3.2% sodium citrate anticoagulant, thiab cov ntshav tau sau rau 2.0 mL.Cov qauv npaj hom yog tag nrho cov ntshav lossis ntshav.Tam sim ntawd tom qab sau, invert thiab sib tov 5-8 zaug.Tom qab centrifugation, nqa lub plasma sab saud rau siv.Haum rau kev sim coagulation, PT, APTT, coagulation factor kuaj.
