Classification thiab piav qhia ntawmcov hlab ntshav
1. Cov hlab ntsha uas muaj lub hau liab, lub raj ntim ntshav tsis muaj tshuaj ntxiv, siv rau niaj hnub cov ntshav biochemistry, cov txhab nyiaj hauv ntshav thiab cov kev ntsuam xyuas serology.
2. Cov txiv kab ntxwv-liab lub taub hau npog ntawm cov hlab ntsha ceev ceev muaj cov coagulant nyob rau hauv cov ntshav sau raj kom ceev cov txheej txheem coagulation.Lub raj xa dej nrawm tuaj yeem coagulate cov ntshav sau hauv 5 feeb, thiab tsim nyog rau kev kuaj ntshav thaum muaj xwm txheej ceev.
3. Lub hau kub ntawm lub inert sib cais gel accelerator raj, thiab inert sib cais gel thiab coagulant yog ntxiv rau cov ntshav sau raj.Tom qab cov qauv no yog centrifuged, lub inert sib cais gel tuaj yeem cais cov kua dej (cov ntshav los yog ntshav) thiab cov khoom siv (cov qe ntshav liab, cov qe ntshav dawb, platelets, fibrin, thiab lwm yam) nyob rau hauv cov ntshav thiab ua kom tag nrho hauv nruab nrab. lub xeem raj los tsim ib tug barrier.ua kom ruaj khov.Procoagulants tuaj yeem qhib lub coagulation mechanism sai sai thiab ua kom cov txheej txheem coagulation, thiab tsim nyog rau kev kuaj ntshav biochemical thaum muaj xwm txheej ceev.
4. Heparin anticoagulation raj muaj lub hau ntsuab, thiab heparin ntxiv rau hauv cov hlab ntshav.Heparin ncaj qha muaj cov nyhuv antithrombin, uas tuaj yeem ua rau lub sijhawm coagulation ntawm cov qauv.Nws yog qhov tsim nyog rau kev kuaj ntshav liab fragility, kuaj ntshav roj, kuaj hematocrit, erythrocyte sedimentation tus nqi thiab kev txiav txim siab dav dav biochemical, tab sis tsis haum rau kev kuaj ntshav coagulation.Heparin ntau dhau tuaj yeem ua rau cov qe ntshav dawb sib sau ua ke thiab siv tsis tau rau kev suav cov qe ntshav dawb.Nws kuj tseem tsis tsim nyog rau kev faib cov leukocyte vim tias nws tuaj yeem ua rau cov ntshav cov yeeb yaj kiab stained nrog lub teeb xiav tom qab.
5. Lub teeb ntsuab lub taub hau ntawm lub plasma cais raj, ntxiv heparin lithium anticoagulant rau inert sib cais roj hmab raj, tuaj yeem ua tiav lub hom phiaj ntawm kev sib cais ntawm cov ntshav sai sai, uas yog qhov kev xaiv zoo tshaj plaws rau kev kuaj xyuas electrolyte, thiab tseem tuaj yeem siv rau niaj hnub. Kev ntsuas ntshav biochemical thiab ntshav ntshav thaum muaj xwm txheej ceev xws li ICU Biochemical kuaj.Cov qauv ntshav tuaj yeem thauj khoom ncaj qha rau ntawm lub tshuab thiab ruaj khov rau 48 teev nyob rau hauv tub yees.
6. EDTA anticoagulation tube ntshav cap, ethylenediaminetetraacetic acid (EDTA, molecular hnyav 292) thiab nws cov ntsev yog ib qho amino polycarboxylic acid, uas tuaj yeem ua tau zoo chelate calcium ions hauv cov ntshav kuaj, chelate calcium los yog cov tshuaj calcium.Kev tshem tawm ntawm qhov chaw yuav thaiv thiab txiav cov txheej txheem endogenous lossis exogenous coagulation, yog li tiv thaiv cov qauv ntshav los ntawm coagulating.Nws yog qhov tsim nyog rau kev kuaj ntshav hematological, tsis haum rau kev kuaj ntshav coagulation thiab kuaj ntshav platelet, lossis rau kev txiav txim siab ntawm calcium ion, potassium ion, sodium ion, hlau ion, alkaline phosphatase, creatine kinase thiab leucine aminopeptidase thiab PCR kuaj.
7. Lub raj tshuaj sodium citrate coagulation muaj lub teeb xiav lub hau.Sodium citrate plays cov nyhuv anticoagulant feem ntau los ntawm chelating calcium ions hauv cov qauv ntshav.Muaj feem xyuam rau cov kev sim coagulation, qhov anticoagulant concentration pom zoo los ntawm Standardization Committee ntawm National Provisional Laboratory yog 3.2% lossis 3.8% (sib npaug rau 0.109mol / L lossis 0.129mol / L), thiab qhov piv ntawm anticoagulant rau ntshav yog 1: 9.
8. Sodium citrate erythrocyte sedimentation rate test tube Dub cap, sodium citrate concentration xav tau rau kev kuaj erythrocyte sedimentation tus nqi yog 3.2% (sib npaug rau 0.109mol / L), thiab qhov piv ntawm anticoagulant rau ntshav yog 1: 4.
9. Potassium oxalate/sodium fluoride grey cap, sodium fluoride yog ib qho tsis muaj zog tiv thaiv coagulant, feem ntau ua ke nrog potassium oxalate lossis sodium iodate, qhov piv yog 1 feem ntawm sodium fluoride, 3 feem ntawm potassium oxalate.4mg ntawm qhov sib xyaw no tuaj yeem ua rau 1ml ntawm cov ntshav tsis coagulate thiab inhibit glycolysis hauv 23 hnub.Nws yog ib qho tshuaj zoo rau kev txiav txim siab ntshav qabzib, thiab tsis tuaj yeem siv rau kev txiav txim siab ntawm urea los ntawm txoj kev urease, lossis rau kev txiav txim siab ntawm alkaline phosphatase thiab amylase.Pom zoo rau kev kuaj ntshav qab zib.
