Gel Yellow Blood Collection Tube

Kev sib cais gel cov hlab ntshav tau siv dav hauv cov chaw kuaj mob.Kev sib cais ntawm cov gel tuaj yeem tsim cov txheej txheem kev sib cais ntawm cov khoom siv ntawm tes thiab cov ntshav (plasma), tiv thaiv cov khoom sib pauv ntawm cov qe ntshav thiab ntshav (plasma), thiab ua kom muaj kev ruaj ntseg ntawm cov ntshav (plasma) cov khoom hauv ib lub sijhawm.Separating kua nplaum yog tsim los ntawm silicone roj hmab, macromolecular hydrocarbons, hydrophobic kua nplaum, thiab lwm yam. Raws li cov khoom siv polymer, nws yog insoluble hauv dej thiab inert.Nws yog thixotropic viscous kua nrog qhov ceev ntawm 1.04-1.05 mmol / Nruab nrab ntawm L, nws muaj qhov zoo ntawm oxidation tsis kam, kub tsis kam, tsis kub tsis kam, thiab huab cua nruj.Qhov ceev ntawm cov ntshav yog 1.026-1.031 mmol / L, thiab hematocrit yog 1.090-1.095.Vim yog lub ntiajteb txawj nqus, cov gel sib cais tsuas yog nyob nruab nrab ntawm cov ntshav thiab cov qe ntshav, yog li nyob rau hauv ib txwm muaj xwm txheej, ntshav yuav tshwm sim tom qab centrifugation.Ntshav, cais cov gel, thiab cov qe ntshav 3 pem teb.

Feem ntau muaj ob hom kev sib cais gel ntshav cov hlab feem ntau siv nyob rau hauv lub chaw soj nstuam: ntshav sib cais gel procoagulation raj thiab ntshav plasma cais gel anticoagulation raj.Lub raj xa dej sib cais gel procoagulation raj yog ntxiv cov coagulant rau hauv cov hlab ntim cov ntshav kom txo lub sijhawm cov ntshav coagulation, tau txais cov ntshav sai sai, thiab tshaj tawm cov txiaj ntsig hauv lub sijhawm luv.Cov hlab ntshav ntim cov iav tsis tas yuav ntxiv coagulants, thiab cov ntshav hu rau lub iav raj phab ntsa yuav ua rau coagulation.Txawm li cas los xij, thaum coagulation yam XI thiab XII tuaj rau hauv kev sib cuag nrog cov yas ntim cov hlab ntshav, lawv lub peev xwm ua kom muaj zog yog qhov tsis muaj zog, thiab cov coagulant yuav tsum tau ntxiv kom luv lub sij hawm coagulation.Lub plasma separation gel anticoagulation tube yog txau nrog cov tshuaj tiv thaiv coagulants xws li lithium heparin rau ntawm phab ntsa sab hauv ntawm cov gel cais cov hlab ntshav kom tau raws li qhov xav tau ntawm kev kuaj ntshav biochemical ceev ceev.

Hauv kev siv tswv yim, nws feem ntau pom tias cov nyhuv sib cais ntawm kev sib cais gel ntshav cov hlab ntshav tsis zoo, piv txwv li: hauv qee cov roj hmab sib cais, nws tuaj yeem pom tau tias cov khoom sib cais gel tawg lossis cov roj tee yog ntab rau saum npoo ntawm cov ntshav los yog raug tshem tawm hauv cov ntshav;Cov txheej txheem sib cais gel ntab rau ntawm cov kua dej.saum toj no thiab lwm yam. Sib cais cov gels kuj tuaj yeem cuam tshuam rau qee qhov kev xeem.Hauv peb lub tuam tsev, nws tau pom tias qhov tshwj xeeb batch ntawm reagents thiab cov kua dej sib cais gel accelerating raj reacted nrog rau ib leeg thaum lub sij hawm HBSAg nrhiav tau ntawm Abbott i2000SR nrhiav kom tau qhov system, uas ua rau cov txiaj ntsig tsis zoo.

Daim ntawv no feem ntau txheeb xyuas los ntawm ob yam, uas yog, vim li cas rau qhov tsis zoo ntawm kev sib cais ntawm cov gel cais, thiab kev cuam tshuam ntawm kev taw qhia ntawm kev sib cais gel ntawm kev ntsuas.

1. Cov txheej txheem ntawm kev sib cais cov ntshav thiab ntshav los ntawm kev sib cais gel Separating gel yog thixotropic mucocolloid tsim los ntawm hydrophobic organic compounds thiab silica hmoov.Cov qauv muaj ntau ntawm hydrogen bonds.Lub hav zoov ntawm hydrogen bonds tsim cov tshuaj hauv paus ntawm thixotropy ntawm kev sib cais gel..Lub ntiajteb txawj nqus tshwj xeeb ntawm cov gel sib cais yog khaws cia ntawm 1.05, qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov kua hauv cov ntshav yog kwv yees li 1.02, thiab lub ntiajteb txawj nqus ntawm cov ntshav tsim yog kwv yees li 1.08.Thaum cov gel sib cais thiab cov ntshav coagulated (los yog cov ntshav anticoagulated tag nrho) yog centrifuged nyob rau hauv tib lub raj, Vim lub centrifugal quab yuam siv rau cov sib cais gel, cov hydrogen bond network qauv yog tawg mus rau hauv ib tug saw-zoo li cov qauv, thiab sib cais. gel ua cov kua dej uas tsis muaj viscosity.Vim yog qhov sib txawv ntawm lub ntiajteb txawj nqus, qhov sib cais gel yog thim rov qab thiab stratified los ua peb txheej ntawm cov ntshav txhaws (anticoagulated tag nrho cov ntshav) / cais gel / ntshav (plasma).Thaum lub centrifuge nres rotating thiab poob centrifugal quab yuam, cov saw hais nyob rau hauv lub sib cais gel tsim ib tug network qauv dua los ntawm hydrogen bonds, restore lub thawj high-viscosity gel lub xeev, thiab tsim ib tug cais txheej ntawm cov ntshav (plasma) thiab cov ntshav txhaws (anticoagulated. ntshav tag nrho)..

2. Yog vim li cas rau kev sib cais tsis zoo ntawm kev sib cais gel

2.1 Separating Gel Quality Lub ntiajteb txawj nqus ntawm cov gel sib cais yog nruab nrab ntawm cov ntshav (plasma) thiab cov qe ntshav, uas yog lub hauv paus ntawm lub cev rau kev thim rov qab ntawm cov gel sib cais thiab kev sib cais ntawm cov ntshav (plasma).Yog tias qhov zoo ntawm kev sib cais gel ntawm lub raj xa dej tsis zoo thiab lub ntiajteb txawj nqus tshwj xeeb tsis ua raws li qhov yuav tsum tau ua, nws yuav ua rau muaj kev cuam tshuam ntawm kev sib cais ntawm cov ntshav (plasma), thiab qhov tshwm sim uas cov gel thiab ntshav (plasma) sib cais. intertwined yuav tshwm sim.

2.2 Tsis tiav cov ntshav coagulation Tom qab centrifugation, qee zaum cov kev sib cais gel compartment thiab cov ntshav thiab cov ntshav txhaws tsis tau sib cais tag nrho, thiab fibrin filaments tshwm nyob rau hauv cov ntshav.Yog vim li cas feem ntau yog cov ntshav tsis tag nrho ua ntej centrifugation.Kev ua tsis tiav cov ntshav coagulation tuaj yeem ua rau fibrin sib xyaw hauv cov txheej txheem cais.Lub raj xa dej sib cais roj hmab yuav tsum tau siv kom raug raws li cov lus qhia, thiab cov ntshav tuaj yeem npaj tau los ntawm centrifugation tom qab cov ntshav tau coagulated tag (feem ntau, lub raj yas uas muaj cov coagulant yuav tsum tau muab tso ncaj rau li 30 feeb, thiab cov ntshav. Lub raj xa dej uas tsis muaj cov coagulant yuav tsum tau muab tso ncaj rau 60-90 feeb).high-quality serum qauv.

2.3 Centrifugation kub Lub centrifugation kub muaj qhov cuam tshuam loj rau cov nyhuv ntawm kev sib cais cov ntshav los ntawm kev sib cais gel raj.Cov dej ntshiab tau pom tseeb nyob rau hauv lub inert separating gel accelerated coagulation raj sib cais los ntawm ib tug zoo tib yam centrifuge nyob rau hauv chav tsev kub, tab sis oily hlaws ntawm txawv qhov ntau thiab tsawg tshwm nyob rau hauv 15% mus rau 20% ntawm cov qauv.Ntawm qhov tod tes, tsis muaj cov hlaws oily tau pom nyob rau hauv cov ntshav sib cais los ntawm qhov ntsuas lub raj centrifuged los ntawm qhov kub thiab txias centrifuge.Thaum qhov kub siab tshaj qhov ntsuas kub uas yuav tsum tau muaj rau kev sib cais gel, inert gel yuav yaj hauv cov ntshav.Nws yuav tsis tsuas thaiv thiab kis tus qauv koob thiab cov tshuaj tiv thaiv khob ntawm biochemical analyzer, tab sis kuj muaj kev cuam tshuam loj heev rau qee qhov kev ntsuas biochemical.
