Cov hlab ntshavmuaj anticoagulant
1) Cov hlab ntshav uas muaj heparin sodium los yog heparin lithium: heparin yog mucopolysaccharide uas muaj sulfate pawg, muaj zog tsis zoo, uas muaj kev ua haujlwm ntawm kev ntxiv dag zog rau antithrombin III kom inactivate serine protease, yog li tiv thaiv kev tsim ntawm thrombin, thiab tiv thaiv platelet aggregation thiab Lwm cov teebmeem anticoagulant.Heparin raj feem ntau yog siv rau kev tshawb nrhiav biochemistry thaum muaj xwm txheej ceev thiab ntshav rheology, thiab yog qhov kev xaiv zoo tshaj plaws rau kev kuaj xyuas electrolyte.Thaum kuaj sodium ions hauv cov ntshav kuaj, heparin sodium tsis tuaj yeem siv, thiaj li tsis cuam tshuam rau qhov kev xeem.Nws kuj tsis tuaj yeem siv rau kev suav cov qe ntshav dawb thiab kev faib tawm, vim tias heparin yuav ua rau cov ntshav dawb sib sau ua ke.
2) Sau cov hlab ntsha uas muaj ethylenediaminetetraacetic acid thiab nws cov ntsev (EDTA -): ethylenediaminetetraacetic acid yog ib qho amino polycarboxylic acid, uas tuaj yeem ua tau zoo chelate calcium ions hauv cov ntshav.Lub chelated calcium yuav tshem tawm calcium los ntawm cov tshuaj tiv thaiv taw tes, uas yuav tiv thaiv thiab tshem tawm cov txheej txheem endogenous lossis exogenous 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 lub agglutination ntawm cov qe ntshav thiab cov morphology ntawm cov qe ntshav, Yog li ntawd, Desheng EDTA ntsev (2K, 3K, 2Na) feem ntau yog siv los ua anticoagulants.Nws yog siv rau kev kuaj hematological dav dav, tab sis tsis yog rau cov ntshav coagulation, kab mob thiab kuaj PCR.
3) Cov hlab ntshav uas muaj sodium citrate anticoagulant: sodium citrate plays lub luag haujlwm anticoagulant los ntawm kev ua ntawm calcium ion chelation hauv cov ntshav kuaj.Lub National Committee for Clinical Laboratory Standardization (NCCLS) pom zoo 3.2% lossis 3.8%, thiab qhov piv ntawm cov tshuaj tiv thaiv rau cov ntshav yog 1: 9.Nws yog tsuas yog siv nyob rau hauv fibrinolysis system (prothrombin lub sij hawm, thrombin lub sij hawm, activated ib nrab thrombin lub sij hawm, fibrinogen).Thaum noj ntshav, ua tib zoo saib xyuas cov ntshav kom txaus kom ntseeg tau tias qhov tseeb ntawm qhov ntsuas tau.Tom qab noj cov ntshav, nws yuav tsum tau rov qab tam sim ntawd thiab sib tov 5-8 zaug.
4) Lub raj muaj cov poov tshuaj oxalate / sodium fluoride (1 feem ntawm sodium fluoride thiab 3 qhov chaw poov tshuaj oxalate): sodium fluoride yog cov tshuaj tiv thaiv tsis muaj zog, muaj txiaj ntsig zoo rau kev tiv thaiv kev degradation ntawm cov ntshav qabzib, thiab yog ib qho tshuaj zoo heev rau kev kuaj ntshav qabzib. .Thaum siv nws, nws yuav tsum tau ua tib zoo sib xyaw ua ke maj mam.Nws feem ntau yog siv rau kev kuaj ntshav qabzib, tsis yog rau kev txiav txim siab urea los ntawm txoj kev urease, lossis rau kev kuaj alkaline phosphatase thiab amylase.
