Cov hlab ntshavnrog anticoagulant nyob rau hauv lub raj
1 Cov hlab ntshav uas muaj sodium heparin lossis lithium heparin: Heparin yog mucopolysaccharide uas muaj cov sulfate pawg nrog cov nqi tsis zoo, uas muaj cov txiaj ntsig ntawm kev ntxiv dag zog rau antithrombin III kom inactivate serine protease, yog li tiv thaiv thrombin Tsim, thiab muaj cov nyhuv anticoagulant xws li tiv thaiv. platelet aggregation.Heparin raj feem ntau yog siv rau thaum muaj xwm txheej ceev biochemical thiab kuaj ntshav txaus, thiab yog qhov kev xaiv zoo tshaj plaws rau kev kuaj xyuas electrolyte.Thaum kuaj cov sodium ions hauv cov ntshav kuaj, yuav tsum tsis txhob siv heparin sodium, thiaj li tsis cuam tshuam rau qhov kev xeem.Nws kuj tsis tuaj yeem siv rau kev suav leukocyte thiab sib txawv, vim tias heparin tuaj yeem ua rau leukocyte aggregation.
2 Cov hlab ntshav uas muaj EDTA thiab nws cov ntsev (EDTA-): EDTA yog ib qho amino polycarboxylic acid, uas muaj peev xwm ua tau zoo chelate calcium ions hauv cov ntshav, thiab chelate calcium yuav tshem calcium los ntawm calcium.Kev tshem tawm ntawm cov tshuaj tiv thaiv taw tes yuav tiv thaiv thiab tshem tawm cov txheej txheem endogenous lossis extrinsic coagulation, yog li tiv thaiv cov ntshav coagulation.Piv nrog rau lwm cov tshuaj tiv thaiv coagulants, nws tsis tshua muaj kev cuam tshuam rau cov coagulation ntawm cov ntshav thiab cov morphology ntawm cov qe ntshav, yog li EDTA ntsev feem ntau yog siv.(2K, 3K, 2Na) ua anticoagulants.Nws yog siv rau kev kuaj hematological dav dav, thiab tsis tuaj yeem siv rau cov ntshav coagulation, kab mob thiab kuaj PCR.
3 Cov hlab ntshav uas muaj sodium citrate anticoagulant: Sodium citrate plays anticoagulant nyhuv los ntawm kev ua ntawm chelation ntawm calcium ions hauv cov ntshav.Qhov piv ntawm tus neeg sawv cev rau cov ntshav yog 1: 9, thiab nws yog tsuas yog siv nyob rau hauv lub fibrinolytic system (prothrombin lub sij hawm, thrombin lub sij hawm, activated ib nrab thrombin lub sij hawm, fibrinogen).Thaum sau cov ntshav, ua tib zoo saib xyuas cov ntshav uas tau sau tseg kom ntseeg tau tias qhov tseeb ntawm qhov ntsuas tau.Tam sim ntawd tom qab sau cov ntshav, nws yuav tsum tau inverted thiab sib tov 5-8 zaug.
4 Muaj sodium citrate, qhov concentration ntawm sodium citrate yog 3.2% (0.109mol / L) thiab 3.8%, qhov ntim piv ntawm anticoagulant rau ntshav yog 1: 4, feem ntau siv rau kev kuaj ESR, qhov feem pua ntawm cov tshuaj tiv thaiv coagulant siab dhau thaum nws yog siab, cov ntshav yog diluted, uas yuav ua rau kom lub erythrocyte sedimentation tus nqi.
5 Lub raj muaj cov poov tshuaj oxalate / sodium fluoride (1 feem ntawm sodium fluoride thiab 3 qhov chaw ntawm potassium oxalate): Sodium fluoride yog cov tshuaj tiv thaiv tsis muaj zog, uas muaj txiaj ntsig zoo rau kev tiv thaiv cov ntshav qab zib degradation, thiab yog ib qho tshuaj zoo heev rau kev kuaj ntshav qab zib. .Kev saib xyuas yuav tsum tau coj mus rau invert thiab sib tov maj mam thaum siv.Nws feem ntau yog siv rau kev kuaj ntshav qab zib, tsis yog rau kev txiav txim siab ntawm urea los ntawm txoj kev urease, lossis rau kev kuaj pom ntawm alkaline phosphatase thiab amylase.
