I-PCR Kits vs. Ukuhlolwa Okusheshayo: Iyiphi Elungele Izidingo Zakho?

Emkhakheni wokuhlolwa kokuxilonga, ikakhulukazi esimweni sezifo ezithathelwanayo njenge-COVID-19, izindlela ezimbili eziyinhloko sezisetshenziswe kakhulu: kits PCR kanye nokuhlolwa okusheshayo. Ngayinye yalezi zindlela zokuhlola inezinzuzo zayo kanye nokubi kwayo, ngakho-ke abantu ngabanye nabahlinzeki bezokunakekelwa kwempilo kufanele baqonde umehluko wabo ukuze banqume ukuthi iyiphi indlela elungele izidingo ezithile.

Funda ngamakhithi e-PCR

Amakhithi e-Polymerase chain reaction (PCR) aklanyelwe ukuthola izakhi zofuzo zamagciwane. Indlela izwela kakhulu futhi icacile, okuyenza ibe izinga eligolide lokuxilonga izifo ezinjenge-COVID-19. Ukuhlolwa kwe-PCR kudinga isampula, ngokuvamile eqoqwe nge-swab yamakhala, bese ithunyelwa elabhorethri ukuze ihlaziywe. Inqubo ihilela ukukhulisa i-RNA yegciwane futhi ikwazi ukubona ngisho namanani omkhondo wegciwane.

Enye yezinzuzo eziyinhloko zePCR kitsukunemba kwazo. Bangakwazi ukubona izifo zisanda kuqala, ngisho nangaphambi kokuba kuvele izimpawu, okubalulekile ekulawuleni ukusabalala kwezifo ezithathelwanayo. Okubi, nokho, ukuthi ukuhlolwa kwe-PCR kungathatha noma yikuphi ukusuka emahoreni ambalwa kuya ezinsukwini ezimbalwa ukubuyisela imiphumela, kuye ngomthwalo welebhu kanye namandla okucubungula. Lokhu kubambezeleka kungaba ukonakala okukhulu ezimweni lapho kudingeka khona imiphumela esheshayo, njengezimo eziphuthumayo noma ngenxa yezidingo zohambo.

Hlola ukuhlolwa okusheshayo

Ukuhlola okusheshayo, ngakolunye uhlangothi, kuklanyelwe ukunikeza imiphumela ngesikhathi esifushane, ngokuvamile phakathi kwemizuzu eyi-15 kuya kwengama-30. Lezi zivivinyo ngokuvamile zisebenzisa indlela yokuthola i-antigen ukukhomba amaprotheni athile egciwane. Ukuhlola okusheshayo kuyasebenziseka kalula futhi kungenziwa ezindaweni ezihlukahlukene, okuhlanganisa imitholampilo, amakhemisi, ngisho nasekhaya.

Izinzuzo eziyinhloko zokuhlolwa okusheshayo yijubane nokulula. Bavumela ukuthathwa kwezinqumo ngokushesha, okuzuzisa kakhulu ezindaweni ezifana nezikole, izindawo zokusebenza, nemisebenzi edinga imiphumela esheshayo ukuze kuqinisekiswe ukuphepha. Kodwa-ke, ukuhlola okusheshayo ngokuvamile akuzweli kangako kunokuhlolwa kwe-PCR, okusho ukuthi kungakhiqiza ama-negetive angamanga, ikakhulukazi kubantu abanegciwane eliphansi. Lo mkhawulo ungase uholele emuzweni oyiphutha wokuphepha uma imiphumela engemihle itolikwa ngaphandle kokuhlolwa okwengeziwe.

Iyiphi evumelana kangcono nezidingo zakho?

Ukukhetha phakathi kwamakhithi e-PCR nokuhlola okusheshayo ekugcineni kuncike ezimweni ezithile nezidingo zomuntu noma inhlangano. Uma ukunemba nokutholwa kusenesikhathi kubalulekile, ikakhulukazi kuzilungiselelo ezinobungozi obukhulu noma kubantu abanezimpawu, amakhithi e-PCR ayinketho yokuqala. Kubuye kunconywe ukuqinisekisa ukuxilongwa ngemuva kwemiphumela yokuhlolwa okusheshayo.

Ngokuphambene, uma imiphumela esheshayo idingeka, njengokuhlola umcimbi noma indawo yokusebenza, ukuhlolwa okusheshayo kungase kufaneke kakhulu. Bangakwazi ukwenza izinqumo ngokushesha futhi basize ekuhlonzeni okungase kube nokuqubuka ngaphambi kokuthi kubhebhetheke. Nokho, ngemva komphumela wokuhlolwa okusheshayo omubi, ukuhlolwa kwe-PCR kuyadingeka, ikakhulukazi uma izimpawu noma ukuchayeka okwaziwayo kugciwane kukhona.

Ngokufigqiwe

Kafushane, kokubiliPCR kitskanye nokuhlolwa okusheshayo kudlala indima ebalulekile emkhakheni wokuhlolwa kokuxilonga. Ukuqonda umehluko, amandla, kanye nemikhawulo yabo kubalulekile ekwenzeni izinqumo ezisekelwe ezidingweni nezimo zomuntu ngamunye. Kungakhathaliseki ukuthi ukhetha ukunemba kwekhithi ye-PCR noma ukunethezeka kokuhlolwa okusheshayo, umgomo omkhulu uyafana: ukuphatha ngempumelelo nokulawula ukusabalala kwezifo ezithathelwanayo.
