I-PCR Kits vs. Uvavanyo oluKhawulezayo: Yeyiphi Eyeyona Ilungele IiMfuno Zakho?

Kwinkalo yovavanyo lokuxilonga, ngakumbi kumxholo wezifo ezosulelayo ezifana ne-COVID-19, iindlela ezimbini eziphambili ziye zaba zezona zisetyenziswa kakhulu: iikiti zePCR kunye novavanyo olukhawulezayo. Nganye kwezi ndlela zokuvavanya zineenzuzo zayo kunye nokungalunganga, ngoko ke abantu kunye nababoneleli bezempilo kufuneka baqonde ukungafani kwabo ukugqiba ukuba yeyiphi indlela efanelekileyo kwiimfuno ezithile.

Funda malunga nezixhobo zePCR

Iikhithi zePolymerase chain reaction (PCR) ziyilelwe ukufumanisa imathiriyeli yemfuzo yeentsholongwane. Indlela inobuntununtunu kakhulu kwaye ithe ngqo, iyenza ibe ngumgangatho wegolide wokufumanisa usulelo olufana ne-COVID-19. Uvavanyo lwe-PCR lufuna isampulu, edla ngokuqokelelwa nge-swab yeempumlo, ethi emva koko ithunyelwe elabhoratri ukuze ihlalutywe. Le nkqubo ibandakanya ukukhulisa i-RNA yentsholongwane kwaye inokubona nomthamo wentsholongwane.

Enye yeenzuzo eziphambili zeIikhithi zePCRkukuchaneka kwazo. Banokwazi ukubona usulelo kumanqanaba abo okuqala, nangaphambi kokuba kuvele iimpawu, nto leyo ebalulekileyo ekulawuleni ukusasazeka kwezifo ezosulelayo. Icala eliphantsi, nangona kunjalo, lelokuba iimvavanyo ze-PCR zinokuthatha naphi na ukusuka kwiiyure ezimbalwa ukuya kwiintsuku ezimbalwa ukubuyisela iziphumo, ngokuxhomekeke kumthwalo welabhu kunye namandla okusebenza. Oku kulibaziseka kunokuba yingozi enkulu kwiimeko apho kufuneka iziphumo ezikhawulezayo, ezifana nongxamiseko okanye ngenxa yeemfuno zokuhamba.

Phonononga uvavanyo olukhawulezayo

Iimvavanyo ezikhawulezayo, kwelinye icala, zenzelwe ukunika iziphumo ngexesha elifutshane, ngokuqhelekileyo phakathi kwe-15 ukuya kwimizuzu engama-30. Olu vavanyo lukholisa ukusebenzisa indlela yokubona i-antigen ukuchonga iiproteni ezithile kwintsholongwane. Uvavanyo olukhawulezayo lusebenziseka lula kwaye lunokulawulwa kwiindawo ezahlukeneyo, kubandakanya iikliniki, iikhemesti, kunye nasekhaya.

Iinzuzo eziphambili zokuvavanya ngokukhawuleza zikhawuleza kunye nokulula. Bavumela ukwenziwa kwezigqibo ngokukhawuleza, nto leyo eyinzuzo ngokukodwa kwiimeko ezifana nezikolo, iindawo zokusebenza, kunye nemisebenzi efuna iziphumo ezikhawulezileyo ukuqinisekisa ukhuseleko. Nangona kunjalo, iimvavanyo ezikhawulezayo ziqhelekile ukuba nobuntununtunu kunovavanyo lwe-PCR, okuthetha ukuba zinokuvelisa izinto ezingezizo ezingezizo, ngakumbi kubantu abanomthamo wentsholongwane egazini. Lo mda unokukhokelela kuluvo olungeyonyani lokhuseleko ukuba iziphumo ezingalunganga zitolikwa ngaphandle kovavanyo olongezelelweyo.

Yeyiphi eyona ifanele iimfuno zakho?

Ukhetho phakathi kweekhithi zePCR kunye novavanyo olukhawulezayo ekugqibeleni luxhomekeke kwiimeko ezithile kunye neemfuno zomntu okanye umbutho. Xa ukuchaneka kunye nokufunyanwa kwangoko kubaluleke kakhulu, ngakumbi kwiindawo ezinomngcipheko ophezulu okanye kubantu abaneempawu, iikiti ze-PCR zikhetho lokuqala. Kukwacetyiswa ukuba uqinisekise ukuxilongwa emva kweziphumo zovavanyo olukhawulezayo.

Ngokuchasene noko, ukuba iziphumo ezikhawulezileyo ziyafuneka, njengokujongwa kwisiganeko okanye kwindawo yokusebenza, uvavanyo olukhawulezileyo lunokufaneleka ngakumbi. Banokuququzelela ukwenziwa kwezigqibo ngokukhawuleza kwaye bancede ekuchongeni uqhambuko olunokwenzeka ngaphambi kokuba lunyuke. Nangona kunjalo, emva kwesiphumo sovavanyo olukhawulezayo olubi, uvavanyo lwe-PCR luyimfuneko, ngakumbi ukuba kukho iimpawu okanye ukuvezwa kwentsholongwane okwaziwayo.

Isishwankathelo

Ngamafutshane, zombiniIikhithi zePCRkunye novavanyo olukhawulezayo ludlala indima ebalulekileyo kwinkalo yovavanyo lokuxilonga. Ukuqonda iiyantlukwano zabo, amandla, kunye nezithintelo kubalulekile ekwenzeni izigqibo ezisekelwe kwiimfuno kunye neemeko zomntu ngamnye. Kungakhathaliseki ukuba ukhetha ukuchaneka kwekiti ye-PCR okanye ukulungelelaniswa kovavanyo olukhawulezayo, injongo yokugqibela iyafana: ukulawula ngokufanelekileyo nokulawula ukusasazeka kwezifo ezithathelwanayo.
