NgoJuni 2, 2021 |Ukuthotyelwa, ubugwenxa boMthetho kunye noNyango, iZixhobo kunye neZixhobo, iiNdaba zeLebhu, ukuSebenza kweLebhu, iPathology yeLabhoratri, uLawulo kunye nokuSebenza
Nangona uvavanyo lwelebhu ye-RT-PCR isengumgangatho wegolide xa uxilonga i-COVID-19, uvavanyo lwe-antigen lwasekhaya lubonelela ngeziphumo zovavanyo olulula nolukhawulezayo.Kodwa ngaba zichanile?
Ngaphantsi kweenyanga ezintandathu emva kokuba i-US Food and Drug Administration (FDA) ikhuphe u-Ellume ugunyaziso lokuqala lokusebenzisa olungxamisekileyo (EUA) kuvavanyo lokuxilonga lwe-SARS-CoV-2 lwe-COVID-19 ekhaya, abathengi Iimvavanyo ezinokuthi zenziwe ekhaya zikhule ngokwaneleyo ukuba isayensi edumileyo ipapashe uphononongo lwezixhobo zovavanyo ze-COVID-19 zabathengi.
Iilabhoratri zeklinikhi kunye neengcali zezifo ziyavuma ngokubanzi ukuba uvavanyo lwe-RT-polymerase chain reaction (RT-PCR) iseyeyona ndlela ikhethwayo yokufumanisa isifo se-COVID-19.Nangona kunjalo, ngokweengxelo "zeNzululwazi edumileyo", iimvavanyo ze-antigen zasekhaya ezikhawulezayo ezinokuchonga ngokuchanekileyo abantu abathwele inani elikhulu leentsholongwane ziba sisixhobo esibalulekileyo sokulwa nokusasazeka kwe-coronavirus.
“Siphonononge uvavanyo lwe-COVID-19 oludumileyo lwasekhaya.Nantsi into esiyifundileyo: Zininzi nangakumbi iinketho zokuvavanyelwa i-COVID ekhaya, yonke into ekufuneka uyazi, ”iSayensi edumileyo yavavanya ngokulula ukusetyenziswa kunye nokusebenza kolu vavanyo lulandelayo:
Uninzi lweemvavanyo zamva nje zekhaya aluvumeli kuphela abasebenzisi ukuba baqokelele ii-swabs zabo okanye iisampulu zamathe, kodwa ezinye zinokubonelela ngeziphumo ngaphantsi kweyure, ezinokuthi zithunyelwe kwi-smartphone yomsebenzisi.Ngokuchaseneyo, iikiti zokuqokelelwa kwekhaya ezibuyiselwe kwilebhu yeklinikhi ukuze zivavanywe zinokuthatha iiyure ezingama-48 okanye ngaphezulu ukuba zithunyelwe kwaye ziqwalaselwe.
UMara Aspinall, unjingalwazi kwiSikolo sezeMpilo kwiYunivesithi yaseArizona, uxelele iSayensi edumileyo: “Okukhona sisenza uvavanyo olulula, oluqhelekileyo, lwasekhaya, kokukhona silufuna kancinci.”Iyakuba ngumkhwa, njengokuxukuxa amazinyo, ”wongeze watsho.
Nangona kunjalo, kwi "Pathologists zibongoza ukuba zilumke kwiiKhithi zoVavanyo ze-COVID-19 ekhaya", iMedPage namhlanje ixele kwingxelo yeendaba kwiKholeji yaseMelika yeePathologists (CAP) nge-11 kaMatshi, ichaza ukuba i-COVID-19 ekhaya -19. Ukungalungi kokufumanisa.
Imiba ekhankanyiweyo ibandakanya iisampulu ezingonelanga kunye nokuphathwa ngendlela engafanelekanga okunokukhokelela kwiziphumo ezingachanekanga, kunye nokungaqiniseki malunga nokuba uvavanyo lwe-antigen ekhaya luza kubhaqa na iintlobo ezahlukeneyo ze-COVID-19.
Uvavanyo lwe-Quest Direct kunye ne-LabCorp Pixel-zombini zithunyelwa kwilebhu yenkampani kuvavanyo lwe-PCR-kwizalathi-manani ezibini eziphambili zobuntununtunu bokusebenza (isivumelwano sepesenti esivumayo) kunye neenkcukacha (imvumelwano yepesenti engalunganga) Amanqaku aphezulu.Ngokweengxelo "zeNzululwazi eNgcotshiweyo", uvakalelo kunye neenkcukacha zolu vavanyo lusondele kwi-100%.
Isayensi edumileyo ifumanise ukuba olu vavanyo lulula ukulusebenzisa kwaye lugqibe kwelokuba zisisixhobo esiluncedo (ukuba asifezekanga) kumlo ochasene ne-COVID-19.
"Ukuba awugonywanga kwaye uneempawu, ziyindlela elungileyo yokuqinisekisa usulelo lwe-COVID-19 ngaphandle kokubeka umngcipheko wokuphuma," utshilo iSayensi edumileyo kwinqaku layo."Ukuba awugonywanga kwaye awunazimpawu kwaye ufuna nje ukwazi ukuba unokuthatha inxaxheba ngokukhuselekileyo kwisidlo sangokuhlwa sosapho okanye kwimidlalo yebhola ekhatywayo, uvavanyo ekhaya kuseyindlela engafezekanga yokuzivavanya.Khumbula: ukuba iziphumo zovavanyo zisithi awunayo , Iziphumo zisenokuba zingalunganga.Ukuba awunxibi imaski, unokuthi ngempazamo ubonakale kwabanye abantu ngaphakathi kweenyawo ezintandathu kwabanye. ”
Ngokuduma kovavanyo lwe-COVID-19 ekhaya, iilabhoratri zeklinikhi ezenza uvavanyo lwe-RT-PCR zinokunqwenela ukunika ingqwalasela enkulu kwisidingo sovavanyo olukhawulezayo lwe-antigen ekhaya, ngakumbi ngoku ezinye iimvavanyo zifumaneka ngaphandle komyalelo.
Uhlaziyo lweCoronavirus (COVID-19): I-FDA igunyazisa uvavanyo lwe-antigen njengovavanyo lokuqala kwikhawuntara, uvavanyo lokuxilonga ekhaya ngokupheleleyo lwe-COVID-19
