Kungekudala emva kokuba u-Abbott egqibe unikezelo lwezigidi ezili-150 zovavanyo lwe-antigen olukhawulezileyo kurhulumente womanyano ukuze lusasazwe ngokubanzi ekuphenduleni ubhubhani we-COVID-19, abaphandi abasuka kumaZiko oLawulo lweSifo kunye noThintelo (CDC) bapapashe uphononongo oluchaza ukuba uxilongo olusekwe kwikhadi lunokuthi. Ungosuleli Malunga nesibini kwisithathu seziganeko ezingenazimpawu.
Uphononongo lwenziwe kunye namagosa ezempilo asekuhlaleni ePima County, Arizona, engqonge iTucson City.Uphononongo luqokelele iisampulu ezidityanisiweyo kubantu abadala abangaphezu kwe-3,400 kunye nolutsha.Enye i-swab yavavanywa kusetyenziswa uvavanyo lwe-Abbott lwe-BinaxNOW, ngelixa enye yaqhutyelwa kusetyenziswa uvavanyo lwe-PCR-based test molecular.
Phakathi kwabo bavavanya ukuba banayo na, abaphandi bafumanise ukuba uvavanyo lwe-antigen lufumanise ngokuchanekileyo usulelo lwe-COVID-19 kwi-35.8% yabo bangakhange baxele naziphi na iimpawu, kunye ne-64.2% yabo bathi baziva bengaphilanga kwiiveki ezimbini zokuqala.
Nangona kunjalo, iintlobo ezahlukeneyo zovavanyo lwe-coronavirus azinakuyilwa ngokufanayo kwiindawo ezahlukeneyo kunye neemeko, kwaye zinokwahluka ngokwezinto ezikhutshiweyo kunye nexesha lokusetyenziswa.Njengoko u-Abbott (Abbott) wachazayo kwingxelo, iimvavanyo zayo ziqhube ngcono ekufumaneni abantu abanamandla osulelo kunye nokusasaza izifo (okanye iisampuli eziqulethe iintsholongwane eziphilayo).
Inkampani yachaza ukuba "i-BinaxNOW ilunge kakhulu ekufumaneni abantu abosulelayo," ekhomba abathathi-nxaxheba abanomdla.Uvavanyo luchonge i-78.6% yabantu abanokulima intsholongwane kodwa i-asymptomatic kunye ne-92.6% yabantu abaneempawu.
Uvavanyo lwe-immunoassay luqulethwe ngokupheleleyo kwincwadana yephepha ubungakanani bekhadi lesikweletu kunye ne-cotton swab efakwe kwaye ixutywe kunye namaconsi kwibhotile ye-reagent.Uluhlu lwemigca enemibala lubonakala lunika iziphumo ezilungileyo, ezimbi okanye ezingasebenziyo.
Uphononongo lwe-CDC lufumanise ukuba uvavanyo lwe-BinaxNOW lukwachaneke ngakumbi.Phakathi kwabathathi-nxaxheba ababonakalisa iimpawu ezichaza iimpawu zesifo kwiintsuku ze-7 ezidlulileyo, uvakalelo lwaluyi-71.1%, enye yokusetyenziswa okugunyazisiweyo kovavanyo oluvunywe yi-FDA.Kwangaxeshanye, idatha yeklinikhi ka-Abbott ibonise ukuba ubuntununtunu beqela elifanayo lezigulane ngama-84.6%.
Inkampani yathi: "Ngokulinganayo, ezi datha zibonisa ukuba ukuba isigulane asinazo iimpawu kwaye umphumo ubi, i-BinaxNOW iya kunika impendulo echanekileyo ye-96.9% yexesha," inkampani ibhekisela kumlinganiselo othile wovavanyo.
Amaziko aseMelika oLawulo lweSifo kunye noThintelo (CDC) avumelene novavanyo, esithi uvavanyo lwe-antigen olukhawulezayo lunesiphumo esisezantsi sobuxoki (nangona kukho imida xa kuthelekiswa novavanyo lwe-PCR oluqhutywa yilabhoratri) ngenxa yokusebenziseka kwayo ngokulula kunye nokukhawuleza. processing Ixesha kunye neendleko eziphantsi zisesona sixhobo sokuhlola esibalulekileyo.Imveliso kunye nokusebenza.
Abaphandi bathi: "Abantu abazaziyo iziphumo zovavanyo oluqinisekileyo phakathi kwemizuzu eli-15 ukuya kwengama-30 banokuvalelwa bodwa ngokukhawuleza kwaye banokuqalisa umkhondo wokunxibelelana kwangoko kwaye basebenza ngakumbi kunokubuyisela iziphumo zovavanyo kwiintsuku ezimbalwa kamva.""Uvavanyo lwe-antigen lusebenza ngakumbi."Ixesha lokutshintsha ngokukhawuleza linokunceda ukunciphisa ukusasazeka ngokuchonga abantu abosulelekileyo ukuba bahlaliswe bodwa ngokukhawuleza, ngakumbi xa besetyenziswa njengenxalenye yesicwangciso sovavanyo olulandelelanayo. ”
U-Abbott uthe kwinyanga ephelileyo uceba ukuqalisa ukunika iimvavanyo zeBinaxNOW ngokuthe ngqo ukuthengwa kwezorhwebo ukuze kusetyenziswe ekhaya nakwindawo ngababoneleli bezempilo, kwaye uceba ukuhambisa ezinye iimvavanyo ze-30 yezigidi ze-BinaxNOW ekupheleni kuka-Matshi, kunye nenye i-90 yezigidi ukuya. ekupheleni kukaJuni.
