Mu myaka yashize, uburyo bwa PCR burigihe (polymerase chain reaction) bwahinduye urwego rwo kurwanya indwara zanduza. Ibi bikoresho byifashishwa mu gupima molekuline byateje imbere cyane ubushobozi bwacu bwo kumenya, kubara, no gukurikirana indwara ziterwa na virusi mugihe nyacyo, biganisha ku gucunga neza indwara zanduza. Iyi ngingo iragaragaza ingaruka zikomeye za sisitemu nyayo ya PCR mugihe cyo kurwanya indwara zandura, yibanda ku byiza byabo, kubishyira mu bikorwa, ndetse n’ubushobozi buzaza.
Sisitemu nyayo ya PCRtanga umubare wingenzi wingenzi kurenza uburyo bwa gakondo bwo gusuzuma. Kimwe mubigaragara cyane ni umuvuduko wabo no gukora neza. Mugihe umuco gakondo ushingiye kubitera indwara bishobora gufata iminsi cyangwa ibyumweru kugirango utange ibisubizo, igihe nyacyo PCR irashobora gutanga ibisubizo mumasaha. Iki gihe cyihuta cyo guhinduka ni ingenzi mu mavuriro, kuko kwisuzumisha ku gihe bishobora kuganisha ku kuvura ku gihe no ku musaruro mwiza w'abarwayi. Kurugero, kubandura virusi nka COVID-19, PCR nyayo yagize uruhare runini mukworohereza gutahura hakiri kare, bituma ingamba zihuse zita kubuzima rusange.
Ikindi kintu cyingenzi kiranga sisitemu nyayo-PCR nuburyo bukomeye kandi bwihariye. Izi sisitemu zirashobora kumenya ndetse na acide nucleic aside nyinshi, bigatuma bishoboka kumenya urugero ruto cyane rwa virusi. Ubu bushobozi ni ingenzi cyane mubijyanye n'indwara zandura, aho gutahura hakiri kare bishobora gukumira icyorezo no kurwanya ikwirakwizwa. Kurugero, igihe nyacyo PCR yakoreshejwe cyane mugutahura indwara zandurira mu mibonano mpuzabitsina (STIs), igituntu, nizindi ndwara zandura, byemeza ko abantu bavurwa neza mbere yuko bakwirakwiza abandi.
Byongeye kandi, sisitemu nyayo ya PCR iratandukanye kandi irashobora guhuzwa kugirango hamenyekane ubwoko bwinshi bwa virusi, harimo bagiteri, virusi, hamwe nibihumyo. Uku guhuza n'imihindagurikire y'ikirere ni ingenzi cyane mu guhangana n'indwara zandura zigaragara, kuko zituma iterambere ryihuta ry’ibizamini bisuzumwa kugira ngo bikemure ibibazo bishya. Icyorezo cya COVID-19 cyagaragaje ibi, aho PCR nyayo yabaye igipimo cyizahabu cyo gusuzuma SARS-CoV-2, virusi itera indwara. Guhuza byihuse no guteza imbere ibizamini bya virusi nshya byagaragaye ko ari ingenzi mu kurwanya icyorezo no kurengera ubuzima rusange.
Usibye ubushobozi bwo gusuzuma, sisitemu nyayo ya PCR nayo igira uruhare runini mugukurikirana epidemiologiya. Mugukurikirana ubwiyongere bwa virusi hamwe nubwoko butandukanye, sisitemu zirashobora gutanga amakuru yingenzi kugirango amenyeshe ingamba zubuzima rusange. Kurugero, PCR nyayo irashobora gukoreshwa mugukurikirana ikwirakwizwa rya bagiteri zirwanya antibiyotike, bigatuma inzego zubuzima zishyira mubikorwa ingamba zigamije gukumira no kurengera ubuzima bwabaturage.
Urebye imbere, sisitemu nyayo-PCR ifite amasezerano akomeye yo gukoresha mugukumira indwara zanduza. Iterambere ry'ikoranabuhanga nko guhuza ubwenge bwa artile no kwiga imashini biteganijwe ko bizarushaho kunoza ukuri no gukora neza kwa sisitemu. Byongeye kandi, iterambere ryibintu-byitaweho-nyabyo-ibikoresho bya PCR bizatuma ibizamini byoroha, cyane cyane mu turere dukennye cyane aho ibikorwa remezo bya laboratoire bishobora kuba bidahagije.
Muri make,sisitemu nyayo ya PCR zagize ingaruka zihinduka mukurwanya indwara zanduza. Umuvuduko wabo, ibyiyumvo byabo, hamwe nuburyo bwinshi bituma uba igikoresho cyingirakamaro mukurwanya indwara zanduza. Mu gihe ikoranabuhanga rikomeje gutera imbere, ubushobozi bwa sisitemu nyayo ya PCR mu rwego rwo kuzamura ibisubizo by’ubuzima rusange no kuzamura umusaruro w’abarwayi bizakomeza kwiyongera, bishimangira umwanya wabo nk'ifatizo ry’imicungire y’indwara zanduye zigezweho.
