Kev lag luam IVD tuaj yeem muab faib ua tsib ntu: kev kuaj mob biochemical, immunodiagnosis, kuaj ntshav cell, kuaj molecular, thiab POCT.
1. Kev kuaj mob biochemical
1.1 Kev txhais thiab kev faib tawm
Cov khoom siv biochemical yog siv nyob rau hauv ib qho kev kuaj pom muaj xws li biochemical analyzers, biochemical reagents, thiab calibrators.Lawv feem ntau muab tso rau hauv tsev kho mob kuaj thiab cov chaw kuaj mob lub cev rau kev kuaj biochemical niaj hnub.
1.2 System classification
2. Immunodiagnosis
2.1 Kev txhais thiab kev faib tawm
Clinical immunodiagnosis muaj xws li chemiluminescence, enzyme-txuas immunoassay, colloidal kub, immunoturbidimetric thiab latex khoom nyob rau hauv biochemistry, tshwj xeeb protein analyzers, thiab lwm yam. Cov kev kho mob nqaim feem ntau yog hais txog chemiluminescence.
Lub chemiluminescence analyzer system yog ib qho kev sib xyaw ua ke ntawm cov tshuaj reagents, cov cuab yeej thiab cov txheej txheem analytical.Tam sim no, kev lag luam thiab kev lag luam ntawm chemiluminescence immunoassay analyzers ntawm kev ua lag luam raug faib raws li qib ntawm automation, thiab tuaj yeem muab faib ua semi-automatic (phaj hom luminescence enzyme immunoassay) thiab tag nrho tsis siv neeg (tube hom luminescence).
2.2 Indication function
Chemiluminescence tam sim no tsuas yog siv rau kev tshawb nrhiav cov qog, cov thyroid ua haujlwm, cov tshuaj hormones, thiab cov kab mob sib kis.Cov kev ntsuam xyuas niaj hnub no suav txog 60% ntawm tag nrho cov nqi lag luam thiab 75% -80% ntawm qhov ntsuas ntim.
Tam sim no, cov kev ntsuam xyuas no suav txog 80% ntawm kev ua lag luam.Qhov dav ntawm daim ntawv thov ntawm qee cov pob khoom muaj feem xyuam rau cov yam ntxwv, xws li kev siv tshuaj yeeb thiab tshuaj ntsuam xyuas, uas tau siv dav hauv Tebchaws Europe thiab Tebchaws Meskas, thiab tsawg tsawg.
3. Kev lag luam ntshav
3.1 Lus Txhais
Cov khoom lag luam suav cov ntshav muaj cov tshuaj ntsuam xyuas cov ntshav, cov tshuaj reagents, calibrators thiab cov khoom tswj kom zoo.Hematology analyzer tseem hu ua hematology analyzer, ntsuas ntshav cell, ntshav cell counter, thiab lwm yam. Nws yog ib qho ntawm cov cuab yeej siv dav tshaj plaws rau kev kuaj mob ntawm RMB 100 lab.
Cov ntshav ntsuas ntshav ntsuas cov qe ntshav dawb, cov qe ntshav liab, thiab cov platelets hauv cov ntshav los ntawm txoj kev tiv thaiv hluav taws xob, thiab tuaj yeem tau txais cov ntaub ntawv ntsig txog ntshav xws li hemoglobin concentration, hematocrit, thiab qhov sib piv ntawm txhua lub cell.
Hauv xyoo 1960, kev suav cov ntshav tau ua tiav los ntawm kev siv phau ntawv staining thiab suav, uas yog qhov nyuaj hauv kev ua haujlwm, kev ua haujlwm tsis zoo, tsis zoo hauv kev tshawb pom qhov tseeb, qee qhov kev tshuaj ntsuam xyuas, thiab cov kev xav tau siab rau cov kws kho mob.Ntau yam tsis zoo txwv nws daim ntawv thov hauv kev sim tshuaj.
Nyob rau hauv 1958, Kurt tau tsim ib qho yooj yim-rau-kev khiav hauj lwm cov ntshav cell counter los ntawm combining resistivity thiab electronics technology.
3.2 Kev faib tawm
3.3 Txoj kev loj hlob
Cov ntshav cell technology yog tib yam li cov hauv paus ntsiab lus ntawm kev ntws cytometry, tab sis cov kev ua tau zoo ntawm cov cytometry ntws tau zoo dua, thiab nws tau siv dav hauv cov chaw sim ua cov cuab yeej tshawb fawb tshawb fawb.Tseem muaj qee lub tsev kho mob loj loj uas siv cov cytometry ntws hauv cov chaw kho mob los txheeb xyuas cov ntsiab lus tsim hauv cov ntshav txhawm rau kuaj ntshav cov kab mob.Cov ntshav kuaj ntshav yuav txhim kho nyob rau hauv ib qho kev siv ntau dua thiab kev coj ua ke.
Tsis tas li ntawd, qee cov khoom kuaj biochemical, xws li CRP, glycosylated hemoglobin thiab lwm yam khoom, tau ntim nrog kev kuaj ntshav hauv ob xyoos dhau los.Ib txoj hlab ntshav tuaj yeem ua tiav.Tsis tas yuav siv cov tshuaj rau kev kuaj biochemical.Tsuas yog CRP yog ib yam khoom, uas yuav tsum coj 10 billion chaw lag luam.
4.1 Kev Taw Qhia
Kev kuaj mob Molecular tau yog qhov chaw kub hauv xyoo tas los no, tab sis nws daim ntawv thov kev kho mob tseem muaj kev txwv.Kev kuaj mob molecular yog hais txog daim ntawv thov Molecular cov cuab yeej siv cov protein, thiab ntau yam immunicically nquag molecules cov lwg me me no.Raws li kev tshawb nrhiav sib txawv, nws tuaj yeem muab faib ua kev suav nyiaj hybridization, PCR amplification, gene chip, gene sequencing, mass spectrometry, thiab lwm yam. Tam sim no, kev kuaj mob molecular tau siv dav hauv cov kab mob sib kis, kuaj ntshav, kuaj pom ntxov, kho tus kheej, Cov kab mob caj ces, kev kuaj mob ua ntej yug menyuam, cov ntaub so ntswg ntaus ntawv thiab lwm yam.
4.2 Kev faib tawm
4.3 Kev ua lag luam
Kev kuaj mob molecular yog siv dav hauv cov kab mob sib kis, kuaj ntshav thiab lwm yam haujlwm.Nrog rau kev txhim kho ntawm tib neeg kev ua neej nyob, yuav muaj kev paub ntau dua thiab xav tau kev kuaj mob molecular.Txoj kev loj hlob ntawm kev lag luam kho mob thiab kev noj qab haus huv tsis txwv rau kev kuaj mob thiab kev kho mob, tab sis txuas ntxiv mus rau kev tiv thaiv kev sib deev tshuaj.Nrog rau kev txiav txim siab ntawm tib neeg daim ntawv qhia noob, kev kuaj mob molecular muaj kev cia siab dav hauv kev kho tus kheej thiab txawm tias siv ntau.Kev kuaj mob molecular yog tag nrho ntawm ntau yam tshwm sim yav tom ntej, tab sis peb yuav tsum tau ceev faj txog cov npuas ntawm kev kuaj xyuas kom zoo thiab kev kho mob.
Raws li kev siv thev naus laus zis, kev kuaj mob molecular tau ua rau muaj txiaj ntsig zoo rau kev kuaj mob.Tam sim no, daim ntawv thov tseem ceeb ntawm kev kuaj mob molecular hauv kuv lub tebchaws yog kev kuaj xyuas cov kab mob sib kis, xws li HPV, HBV, HCV, HIV thiab lwm yam.Cov ntawv thov kev kuaj cev xeeb tub kuj tseem paub tab, xws li BGI, Berry thiab Kang, thiab lwm yam, kev tshawb nrhiav DNA dawb hauv cov ntshav hauv plab hauv plab tau maj mam hloov cov txheej txheem amniocentesis.
5.POCT
5.1 Kev txhais thiab kev faib tawm
POCT yog hais txog cov txheej txheem kev tshuaj ntsuam xyuas uas cov kws tsis yog kws tshaj lij siv cov cuab yeej nqa tau yooj yim los soj ntsuam cov neeg mob sai thiab tau txais txiaj ntsig zoo nyob ib puag ncig tus neeg mob.
Vim muaj qhov sib txawv loj hauv kev sim cov txheej txheem, muaj ntau txoj hauv kev rau cov khoom sib koom ua ke, qhov kev siv ntau yam nyuaj los txiav txim siab, qhov kev ntsuas qhov tshwm sim yog qhov nyuaj los lav, thiab kev lag luam tsis muaj cov qauv kev tswj hwm zoo, thiab nws yuav nyob twj ywm. chaotic thiab dispersed rau lub sij hawm ntev.Nrog rau kev siv keeb kwm kev loj hlob ntawm POCT thoob ntiaj teb loj heev Alere, M&A kev koom ua ke hauv kev lag luam yog tus qauv kev txhim kho zoo.
5.2 Cov khoom siv POCT feem ntau siv
1. Ceev ceev ntsuas ntshav qabzib ntsuas
2. Ceev ceev ntshav roj analyzer
