Izindaba - Umthelela Wezinhlelo Ze-PCR Zesikhathi Sangempela Ekulawuleni Izifo Ezithathelwanayo

Eminyakeni yamuva nje, ukuvela kwezinhlelo ze-PCR (i-polymerase chain reaction) yesikhathi sangempela kuguqule umkhakha wokulawula izifo ezithathelwanayo. Lawa mathuluzi okuxilonga amangqamuzana athuthukile athuthukise kakhulu ikhono lethu lokubona, ukulinganisa, nokuqapha amagciwane ngesikhathi sangempela, okuholela ekulawuleni ngempumelelo izifo ezithathelwanayo. Lesi sihloko sihlola umthelela ojulile wezinhlelo ze-PCR zesikhathi sangempela ekulawuleni izifo ezithathelwanayo, sigxile ezinhlelweni zazo, izinhlelo zokusebenza, namandla esikhathi esizayo.

Izinhlelo ze-PCR zesikhathi sangempelanikeza inani lezinzuzo ezibalulekile ngaphezu kwezindlela zokuxilonga zendabuko. Enye yezinto eziphawuleka kakhulu ijubane nokusebenza kahle kwazo. Nakuba izindlela zokuthola igciwane lesandulela ngculaza ezisekelwe esikweni zingathatha izinsuku noma ngisho amasonto ukukhiqiza imiphumela, i-PCR yesikhathi sangempela inganikeza imiphumela phakathi namahora. Lesi sikhathi sokushintsha ngokushesha sibalulekile kuzilungiselelo zomtholampilo, njengoba ukuxilongwa ngesikhathi kungaholela ekwelapheni okufika ngesikhathi kanye nemiphumela engcono yesiguli. Isibonelo, ezifweni ezibangelwa amagciwane njenge-COVID-19, i-PCR yesikhathi sangempela ibambe iqhaza elibalulekile ekusizeni ukutholwa kusenesikhathi, okuvumela izindlela zokuphendula zezempilo zomphakathi ngokushesha.

Esinye isici esibalulekile sezinhlelo ze-PCR zesikhathi sangempela ukuzwela kwazo okuphezulu nokucaciswa kwazo. Lezi zinhlelo zingakwazi ukubona ngisho namanani amancane e-nucleic acid, okwenza kube nokwenzeka ukuhlonza amazinga aphansi kakhulu amagciwane. Leli khono libaluleke kakhulu emkhakheni wezifo ezithathelwanayo, lapho ukutholakala kusenesikhathi kungavimbela ukuqubuka nokulawula ukusakazeka. Isibonelo, i-PCR yesikhathi sangempela iye yasetshenziswa kabanzi ukuthola izifo ezithathelwana ngocansi (STIs), isifo sofuba, nezinye izifo ezithathelwanayo, ukuqinisekisa ukuthi abantu bathola ukwelashwa okufanele ngaphambi kokuba basakaze ukutheleleka kwabanye.

Ukwengeza, izinhlelo ze-PCR zesikhathi sangempela zisebenza ngezindlela eziningi futhi zingashintshwa ukuze kutholwe amagciwane ahlukahlukene, okuhlanganisa amagciwane, amagciwane, nesikhunta. Lokhu kuzivumelanisa nezimo kubalulekile ekuphenduleni izifo ezithathelwanayo ezivelayo, njengoba kwenza ukuthuthukiswa okusheshayo kokuhlolwa kokuxilonga ukubhekana nezinsongo ezintsha. Ukuqubuka kwe-COVID-19 kukugqamisile lokhu, lapho i-PCR yesikhathi sangempela iba indinganiso yegolide yokuxilonga i-SARS-CoV-2, igciwane elidala lesi sifo. Ukuzivumelanisa nezimo ngokushesha nokuthuthukisa izivivinyo zamagciwane amasha kufakazele ukuthi kubaluleke kakhulu ekulawuleni ukuqubuka nokuvikela impilo yomphakathi.

Ngokungeziwe emandleni okuxilonga, izinhlelo ze-PCR zesikhathi sangempela nazo zidlala indima ebalulekile ekuqashweni kwezifo eziwumshayabhuqe. Ngokuqapha ukwanda kwe-pathogen kanye nokuhlukahluka kofuzo, lezi zinhlelo ziyakwazi ukunikeza idatha ebalulekile ukwazisa amasu ezempilo yomphakathi. Isibonelo, i-PCR yesikhathi sangempela ingasetshenziswa ukulandelela ukusabalala kwamagciwane amelana nama-antibiotic, okuvumela iziphathimandla zezempilo ukuthi zisebenzise ukungenelela okuhlosiwe ukuze kunqandwe ukumelana nokuvikela impilo yomphakathi.

Uma ubheka phambili, amasistimu e-PCR esikhathi sangempela anesithembiso esihle sokusetshenziselwa ukulawula izifo ezithathelwanayo. Intuthuko yezobuchwepheshe efana nokuhlanganiswa kobuhlakani bokwenziwa nokufunda komshini kulindeleke ukuthi kuthuthukiswe ukunemba nokusebenza kahle kwalezi zinhlelo. Ukwengeza, ukuthuthukiswa kwamadivayisi e-PCR esikhathi sangempela kuzokwenza ukuhlola kube lula, ikakhulukazi ezindaweni ezingenazo izinsiza lapho ingqalasizinda yelabhorethri evamile ingase inganele.

Ngokufigqiwe,izinhlelo ze-PCR zesikhathi sangempela zibe nomthelela oguquguqukayo ekulawuleni izifo ezithathelwanayo. Ijubane lazo, ukuzwela, nokuguquguquka kwazo kuzenza zibe ithuluzi elibalulekile ekulweni nezifo ezithathelwanayo. Njengoba ubuchwepheshe buqhubeka nokuvela, amandla ezinhlelo ze-PCR zesikhathi sangempela zokuthuthukisa izimpendulo zezempilo zomphakathi kanye nokwenza ngcono imiphumela yesiguli azoqhubeka nokukhula, aqinise indawo yawo njengesisekelo sokulawulwa kwezifo ezithathelwanayo zesimanje.
