Ithetha ukuthini iPCR? -Ilungile kwaye ayiquki [Fumana]
Ukuthetha nge-CRP kuthetha ukuba sempilweni ngokwasemzimbeni kumntu wonke. Yiyo loo nto kubalulekile ukuba ungala ukwenza uvavanyo lwe-PCR ngexesha olucelwe ngalo ngabasemagunyeni bezonyango. Kwingxaki yezempilo efana nale sinayo, ngenxa yobhubhani we-Covid 19, abantu abaninzi ngakumbi basengozini engenakuthelekiswa nanto ebomini; nto leyo esishiya umyalezo wesazela malunga noxanduva lomntu kunye noluntu.
Ke ngoko, iPCR yenye yezona zibalaseleyo izixhobo zokuhlola izifo usulelo olusulelayo. Kwaye yenye yeendlela eziphambili zokuqalisa ukulwa ne-archaic kunye ne-microorganisms ezintsha eziba yingozi kwimpilo yoluntu.
Ithetha ukuthini iPCR?
I-PCR imele "I-Polymerase Chain Reaction". Kwaye iqulethwe kukwenza uvavanyo lokuxilonga olwenza ukuba kufumaneke isiqwenga sezinto zofuzo ze-pathogen okanye i-microorganism. Ukwenza oku, kuyafuneka ukuba kuqhutywe uphando lophando lwebhubhoratri olwenziwa ngeempumlo kunye ne-buccally.
Olu pho nonongo luya kuququzelela ukuzimisela konyango olusebenzayo nolusebenzayo kwisigulane. Ngoko ke, sinokuthi i I-PCR imele ukubonwa kwezifo ezosulelayo elabhoratri oko kunokubeka impilo yamawaka abantu emngciphekweni.
Umzekelo, olu luphononongo lwezonyango oluqhutywayo ngoku ukubona intsholongwane ye-Covid 19, uhlobo olunobundlongondlongo losulelo lokuphefumla olubangela ukufa okungazange kubonwe ngaphambili. Enkosi kolu vavanyo loxilongo, kube nokwenzeka ukuchonga ukuba ngubani onokuba ngumthwali wosulelo oluxeliweyo.
Kukho konke, i-PCR luvavanyo olufuna ukunakekelwa okukhulu kunokwenzeka kwisicelo sayo, ekubeni ubunzima bayo bokuhlalutya bufuna; kungoko ukubaluleka kokwenziwa ngabasebenzi abaziingcali kulo msebenzi, ekubeni ubunyani kunye nokuthembeka kweziphumo kuxhomekeke kuyo.

Ithetha ukuthini i-PCR positive?
Uvavanyo lwe-PCR luthetha ukuba iziphumo zoxilongo ubungqina bobukho kunye nobukho besifo kumzimba wesigulana. Umzekelo, kwimeko ye-Covid 19, ukuba uvavanyo luvelisa iziphumo ezilungileyo, isigulana kufuneka sithathe uthotho lwamanyathelo kunye nezilumkiso, ukuqala ekufumaneni unyango, ukuhlala yedwa kunye nokuphumla, kunye nokulandela nayiphi na enye iprothokholi yokhuseleko ngokwemiqathango ezempilo, ukuphepha ukusasaza inani losulelo kubemi.
Ke ngoko, i-PCR eqinisekileyo ithetha ukufunyaniswa kwe-pathology yeklinikhi efanelwe ingqwalasela yonyango njengelungelo lomguli ebomini, kunye nenqanaba lokuqala lokumisa ukusasazeka kwentsholongwane, ngaloo ndlela kuncitshiswa inani elincinci lamaxhoba ngezifo ezosulelayo. satsho isifo.
Ithetha ukuthini iPCR engaqukiyo?
I-PCR engaqukiyo ithetha a iziphumo ezingagqibekanga, phantsi kwamathandabuzo, oko kukuthi, akucaci ukuba kukho isifo esosulelayo okanye akukho. Ukungachaneki kwiziphumo kusenokuba ngenxa yezinto ezahlukeneyo zangaphakathi nangaphandle, ezinje: ukuhla koqikelelo lokuqikelelwa komntu ukubona intsholongwane efana ne-Covid 19, inani elincinci legazi lethu elithathiweyo, okanye ngenxa yokusilela kobugcisa okuphazamisayo. kunye nenkqubo yohlalutyo lovavanyo lwe-PCR.
Ke ngoko, i-PCR engaqukiyo ithetha ukuba kunokubakho izizathu ezininzi ezingabeki kukhanya ngokwaneleyo kuxilongo olukhuselekileyo noluqinisekileyo. Kwiimeko ezinje, kufanelekile ukwenza uvavanyo lwesibini ukuze ukwazi ukubona ngokupheleleyo ubukho bentsholongwane ethile eyosulelayo efana ne-Covid 19, uGawulayo, okanye ezinye iintlobo ezahlukeneyo zokungaqondi kakuhle ezinjengomhlaza, phakathi kwezinye.
Ukongeza kwi-PCR, zeziphi ezinye iimvavanyo ezikhoyo?
Ngaphandle kwe-PCR, kukho ezinye iimvavanyo ezikwaziyo ukubona kunye nokufumanisa isifo esosulelayo. Injalo imeko yovavanyo lweSerology, uvavanyo lweHemogram, uvavanyo lweNucleic Acid, phakathi kwabanye. Nangona kunjalo, kweli candelo siza kugxila kuphela kwiimvavanyo ezimbini, i Uvavanyo lwe-Antigen kunye noVavanyo lwe-Antibody.
Uvavanyo lweAntigen
Uvavanyo olukhawulezayo olunobungcali be yenza ukuxilongwa ngokukhawuleza. Oko kukuthi, kwimizuzu nje embalwa, ngaloo ndlela ityhila ubukho okanye hayi usulelo oluthile. Ngobhubhani we-Covid 19, olu hlobo lovavanyo lusebenza kakhulu kwaye luyimfuneko ekubhaqweni kwale ntsholongwane. Ukuyibona ngeentsuku zokuqala zokubamba, okanye kwinqanaba eliphambili.
Olu hlobo lovavanyo lwenziwa ngokuthatha imfihlo yeempumlo kunye nomlomo. Ke ngoko, kuyaqondwa ukuba, xa kusetyenziswa iimvavanyo ezikhawulezayo ezifana nezi, kunokuba yimfuneko ukwenza ezinye iimvavanyo ezinzulu ngakumbi njenge-PCR. Nangona kunjalo ukuphumelela kovavanyo lwe-antigen yenye yeyona ndlela ilungileyo yenkqubo yokuxilonga. Oko kuya kuba negalelo ekuphunyezweni kweprotocol yonyango ukwenzela ukunciphisa isantya apho i-microorganism ethile ihlasela kwaye isasaze usulelo.

Uvavanyo lwe-Antibody
Iqukethe i- uvavanyo lwegazi, oluqheliselwa ukuze kwaziwe ukuba umntu uye wasulelwa ngexesha elithile. Oku kuluncedo ukufumanisa ukuba umntu ebephethe i-Covid 19, okona kubaluleke nangakumbi, kuthathelwa ingqalelo ukuba abantu abaninzi abafumana le ntsholongwane baba ngabathwali be-asymptomatic.
Umzekelo, isiphumo esihle se-Covid 19 sibonisa ukuba isigulana sinokhuselo, okanye amajoni omzimba ngokuchasene ne-Covid. Nangona kunjalo, akukho zifundo zokugqibela ezibonisa ukuba i-antibody ephuhlisiweyo iyakuthintela usulelo lwesibini lwe-Covid 19.
