Ib qho laj thawj tseem ceeb vim li cas cov tshuaj ntsuas ntshav hauv tsev muag lawv cov ntawv xeem ntawm tsuas yog ib nrab ntawm tus nqi ntawm cov khoom lag luam txawv teb chaws yog lawv cov khoom muag qis dua. Tsis tas li ntawd, qhov tseeb tias yuav luag txhua lub tsev kho mob siv cov khoom lag luam txawv teb chaws qhia tias muaj qhov sib txawv ntawm cov khoom siv hauv tsev thiab txawv teb chaws.
Thaum ua tiav kev ruaj ntseg zoo thiab raug nyob rau hauv ib lossis ob pawg ntawm cov ntawv xeem tsis yog qhov nyuaj, kom ntseeg tau tias muaj kev ruaj ntseg thiab raug nyob thoob plaws txhua pawg yog qhov nyuaj. Txawm tias cov tuam txhab lag luam loj thoob ntiaj teb tawm tsam los lav qhov tseeb zoo txhua lub sijhawm. Piv txwv li, Johnson & Johnson tau rov qab los ntawm ntau pawg ntawm cov ntawv xeem thoob ntiaj teb hauv xyoo 2005 vim yog qhov yuam kev coding. Qhov sib txawv ntawm thev naus laus zis no yog nyob rau hauv qhov tseeb tias cov tuam txhab lag luam thoob ntiaj teb feem ntau tuaj yeem tswj kev ruaj ntseg nyob rau hauv 5% thiab qhov tseeb mus rau ntau dua 95%, thaum cov tuam txhab me thiab cov khoom lag luam hauv tsev feem ntau poob qis ntawm cov qib no.
Hauv ntej, cov thev naus laus zis tseem ceeb ntawm kev soj ntsuam ntshav qabzib ceev yog qhov nyuaj heev. Qhov sib txawv ntawm kev siv tshuab ntawm cov neeg tsim khoom tsuas tuaj yeem raug ntaus nqi rau leej twg muaj kev nkag siab zoo dua ntawm cov tshuab. Tsis muaj chaw tsim khoom muaj kev tswj xyuas tag nrho cov thev naus laus zis tseem ceeb. Txhua leej txhua tus tab tom tshawb nrhiav. Johnson & Johnson calibration xwm txheej nyob rau hauv 2005 thiab Roche FDA qhov teeb meem nyob rau hauv lub tebchaws United States nyob rau hauv 2007 ob qho tib si qhia tau hais tias txawm lub sab saum toj thoob ntiaj teb tuam txhab uas muag tsis muaj kiag li kev tswj ntawm ceev ceev ntshav qab zib technology. Yog tias qhov no yog rooj plaub rau cov tuam txhab loj, ces qhov xwm txheej rau cov tuam txhab me tuaj yeem xav txog.
