Ukusukela oko kwaqhambuka ubhubhani we-COVID-19, abantu abaninzi abakhange baziqonde iindlela ezahlukeneyo zokubona, kubandakanya ukubhaqwa kwe-nucleic acid, ukufunyanwa kwe-antibody, kunye nokufunyanwa kwe-antigen.Eli nqaku ikakhulu lithelekisa ezo ndlela zokubona.
Ukuchongwa kwe-Nucleic acid okwangoku "ngumgangatho wegolide" wokufunyanwa kwenoveli coronavirus kwaye ngoku yeyona ndlela iphambili yovavanyo eTshayina.Ukufunyanwa kwe-Nucleic acid kuneemfuno eziphezulu zezixhobo zokubona, ukucoceka kwelabhoratri kunye nabaqhubi, kunye nezixhobo zePCR ezinovakalelo oluphezulu ziyabiza, kwaye ixesha lokubona lide.Ke ngoko, nangona kuyindlela yokuxilongwa, ayisebenzi kuvavanyo olukhulu olukhawulezayo phantsi kwemeko yokungabikho kwehardware.
Xa kuthelekiswa nokufunyaniswa kwe-nucleic acid, iindlela zangoku ezikhawulezayo zokufumanisa ikakhulu zibandakanya ukubhaqwa kwe-antigen kunye nokufunyanwa kwe-antibody.Ukufunyaniswa kwe-antigen kukhangela ukuba kukho iintsholongwane emzimbeni, ngelixa i-antibody ijonga ukuba ngaba umzimba uphuhliswe ukuxhathisa kwi-pathogen emva kosulelo.
Okwangoku, ukufunyaniswa kwe-antibody kuqhele ukufumanisa ii-antibodies ze-IgM kunye ne-IgG kwiserum yabantu.Emva kokuba intsholongwane ihlasele umzimba womntu, kuthatha malunga neentsuku ezi-5-7 ukuba i-antibodies ye-IgM iveliswe, kwaye i-IgG antibodies iveliswa kwiintsuku ezili-10-15.Ke ngoko, kukho ithuba elikhulu lokufunyanwa okuphosiweyo ngokufunyaniswa kwe-antibody, kwaye kusenokwenzeka ukuba isigulana esibhaqiweyo sosulele abantu abaninzi.
Umfanekiso 1:I-NEWGENE Antibody Detection Product
Xa kuthelekiswa nokubhaqwa kwe-antigen, ubhaqo lwe-antigen luyakwazi ukubona intsholongwane ngexesha lokufukamela, isigaba esibukhali okanye inqanaba lokuqala lesi sifo, kwaye ayifuni indawo yelabhoratri kunye nemisebenzi yobungcali.Ukufunyanwa kwe-Antigen kulungeleka ngokukodwa kwiimeko apho izixhobo zonyango zonyango kunye neengcali zingekho.Kubaluleke kakhulu ukubhaqwa kwangoko kunye nonyango lwakwangoko lwezigulana ezinobhubhani we-COVID-19.
Umfanekiso 2:I-NEWGENE Antigen Detection Product
I-Novel Coronavirus Spike Protein Detection Kit ephuhliswe yaze yaveliswa ngu-NEWGENE yenye yeemveliso zokuqala zokubona i-antigen zaphuhliswa e-China.Ibhaliswe yiBritish Medicines and Healthcare Products Regulatory Agency (MHRA), ifumene isatifikethi se-EU CE, kwaye ifakwe ngempumelelo "kuluhlu lwemvume yokuthumela ngaphandle" ye-Chinese Ministry of Commerce.
Imveliso ayigcinanga kuphela iingenelo zokufunyanwa ngokukhawuleza, ukusebenza okulula, iindleko eziphantsi, kunye nokuzinza okulungileyo, kodwa kwakhona kuphucula kakhulu ukufumanisa ukuchaneka kunye nokuchaneka.Kwangaxeshanye, obu buchwepheshe busebenza ngeendlela ezahlukeneyo ekufumaneni ii-coronavirus ezilamlwa yi-ACE2 receptor.Nangona intsholongwane iguqukela kwiinguqu, ikiti yokufumanisa inokufakwa ngokukhawuleza kwisicelo ngaphandle kokulinda ukuphuhliswa kwama-antibodies amatsha, okubonelela ngenkxaso ebalulekileyo yezobuchwepheshe kumsebenzi wokulwa nobhubhane wexesha elizayo.
