Classification thiab piav qhia ntawmcov hlab ntshav
1. Biochemical
Cov hlab ntshav biochemical tau muab faib ua cov raj tsis muaj tshuaj ntxiv (liab cap), coagulation-txhim hlab (txiv kab ntxwv-liab cap), thiab sib cais roj hmab raj (daj cap).
Sab hauv phab ntsa ntawm cov khoom siv zoo-dawb cov ntshav sau cov raj yog sib npaug nrog cov tshuaj kho phab ntsa sab hauv thiab lub qhov ncauj kho tus neeg saib xyuas kom tsis txhob muaj cov cell tawg thaum lub sij hawm centrifugation thiab cuam tshuam rau cov txiaj ntsig kev xeem, thiab sab hauv phab ntsa ntawm lub raj thiab cov kua dej ntshiab. thiab pob tshab, thiab tsis muaj ntshav dai ntawm lub qhov ncauj ntawm lub raj.
Ntxiv nrog rau cov phab ntsa sab hauv ntawm lub raj coagulation yog uniformly coated nrog lub puab phab ntsa kho tus neeg saib xyuas thiab lub nozzle kho tus neeg saib xyuas, cov tshuaj tsuag yog siv nyob rau hauv lub raj kom lub coagulation accelerator sib npaug zos rau lub raj phab ntsa, uas yog yooj yim rau sai sai. thiab tag nrho sib xyaw cov ntshav kuaj tom qab kuaj, uas tuaj yeem txo lub sijhawm coagulation.Thiab tsis muaj nag lossis daus ntawm fibrin filaments kom tsis txhob thaiv lub pinhole ntawm cov khoom siv thaum lub sijhawm ua piv txwv.
Thaum lub raj sib cais roj hmab yog centrifuged, cov gel sib cais yog txav mus rau qhov chaw ntawm lub raj, uas nyob nruab nrab ntawm cov ntshav los yog ntshav thiab cov ntshav tsim cov khoom.Tom qab lub centrifugation tiav lawm, nws solidifies tsim ib tug barrier, uas kiag li cais cov ntshav los yog plasma los ntawm lub hlwb thiab xyuas kom meej stability ntawm cov tshuaj lom neeg muaj pes tsawg leeg., tsis muaj kev hloov pauv tseem ceeb hauv lub tub yees rau 48 teev.
Lub raj roj hmab inert sib cais yog ntim nrog heparin, uas tuaj yeem ua tiav lub hom phiaj ntawm kev sib cais ntawm cov ntshav sai sai, thiab cov qauv tuaj yeem khaws cia rau lub sijhawm ntev.Cov hoses sib cais tau piav qhia saum toj no tuaj yeem siv rau kev soj ntsuam biochemical sai.Kev sib cais gel heparin raj yog tsim nyog rau kev kuaj biochemical thaum muaj xwm txheej ceev, mob hnyav hauv tsev kho mob (ICU), thiab lwm yam. Piv nrog rau cov hlab ntshav, qhov txiaj ntsig loj tshaj plaws yog cov ntshav ntshav (plasma) tuaj yeem sib cais sai, thiab qhov thib ob yog cov tshuaj. muaj pes tsawg leeg ntawm cov ntshav (plasma) tuaj yeem ruaj khov rau lub sijhawm ntev, uas yooj yim rau kev thauj mus los.
2. Anticoagulant
1) Heparin raj (ntsuab cap): Heparin yog ib qho zoo heev anticoagulant, uas muaj kev cuam tshuam me ntsis ntawm cov ntshav, tsis cuam tshuam rau lub ntim ntawm cov qe ntshav liab, thiab tsis ua rau hemolysis.Volume, erythrocyte sedimentation tus nqi thiab kev txiav txim siab dav dav biochemical.
2) Cov hlab ntsha hauv cov ntshav (ntsuab cap): EDTA yog chelated nrog calcium ions hauv cov ntshav, kom cov ntshav tsis coagulate.Feem ntau, 1.0 ~ 2.0 mg tuaj yeem tiv thaiv 1 ml ntawm cov ntshav los ntawm coagulating.Cov tshuaj tiv thaiv coagulant no tsis cuam tshuam rau suav thiab qhov loj ntawm cov qe ntshav dawb, muaj kev cuam tshuam tsawg kawg nkaus ntawm morphology ntawm cov qe ntshav liab, thiab tuaj yeem cuam tshuam kev sib sau ntawm cov platelets, yog li nws tsim nyog rau kev kuaj hematological.Feem ntau, cov txheej txheem ntawm kev txau yog siv los ua kom cov reagent sib npaug ntawm cov phab ntsa ntawm lub raj, kom cov qauv ntshav tuaj yeem sai thiab sib xyaw ua ke tom qab kuaj.
3) Ntshav coagulation raj (xiav cap): ntau npaum li cas kua sodium citrate anticoagulant tsis yog ntxiv rau hauv cov ntshav sau raj.Anticoagulant thiab cov ntsuas ntshav ntim ntim tau ntxiv rau hauv qhov sib piv ntawm 1: 9 rau kev kuaj xyuas cov khoom siv coagulation (xws li PT, APTT).Lub hauv paus ntsiab lus ntawm anticoagulation yog ua ke nrog calcium los tsim cov calcium chelate soluble kom cov ntshav tsis coagulate.Qhov pom zoo anticoagulant concentration xav tau rau kev kuaj hemagglutination yog 3.2% lossis 3.8%, uas yog sib npaug rau 0.109 lossis 0.129 mol / L.Rau kev kuaj ntshav coagulation, yog tias cov ntshav sib piv tsawg dhau, lub sijhawm APTT yuav ncua ntev, thiab cov txiaj ntsig prothrombin (PT) kuj tseem hloov pauv.Yog li ntawd, seb qhov piv ntawm cov tshuaj tiv thaiv coagulant rau qhov ntsuas ntshav ntim ntim yog qhov tseeb lossis tsis yog nyob ntawm hom khoom no.tus qauv tseem ceeb ntawm kev ua tau zoo.
4) ESR raj (dub cap): Cov txheej txheem anticoagulation ntawm cov hlab ntim cov ntshav yog tib yam li cov ntshav coagulation raj, tshwj tsis yog tias sodium citrate anticoagulant thiab cov ntsuas ntshav ntim tau ntxiv hauv qhov piv ntawm 1: 4 rau ESR. kev tshuaj xyuas.
5) Ntshav qab zib raj (grey): Cov tshuaj fluoride ntxiv rau hauv cov hlab ntshav los ua cov tshuaj inhibitor.Vim yog qhov sib ntxiv ntawm cov inhibitor thiab kev kho tshwj xeeb ntawm cov phab ntsa sab hauv ntawm lub raj kuaj, cov khoom qub ntawm cov qauv ntshav tau khaws cia rau lub sijhawm ntev, thiab cov metabolism hauv cov qe ntshav yog qhov tseem ceeb.Nws yog dav siv hauv kev kuaj ntshav qabzib, ntshav qabzib siab, erythrocyte electrophoresis, anti-alkali hemoglobin, thiab piam thaj hemolysis.
