Enye yezindlela zokuxilongwa kwee molecular ezisetyenziswa rhoqo kwi-gynecology yi-PCR-polymerase chain reaction. Ingundoqo yale ndlela ibandakanye ukwanda okwenziwe ngamakhulu angamawaka ngamaxesha e-DNA ye-pathogen, enceda ukuyiqonda ngaphandle kobunzima. Le ndlela ikuvumela ukuba ufumene izifo ezifihliweyo emzimbeni womfazi.
Izinto ezikulo sifundo zinokusebenza njengeendidi ezahlukeneyo zamanzi. Ingaba ngumtsalane, igazi, umchamo, umthi. Ukongezelela, i-smear kwi-PCR ithathwa kwinqanawa yomlomo wesibeleko okanye kwi-mucosa ye-vaginal.
Yibanjwe nini?
Izibonakaliso eziphambili zokuqhuba i-smear kwi- PCR kwabasetyhini zi:
- isigaba esichukumisayo se-STI;
- ukusola ngesiganeko esingapheliyo se-STI;
- ngokukhulelwa okukhulu;
- ukusekwa kwezizathu zokungabikho .
Ngokuqhelekileyo, le ndlela isetyenziswe xa kuyimfuneko ukucacisa ukunyanzelwa kwalo hlobo lwe-pathogen kwi-antibiotics. Ukongezelela, i-PCR isetyenziselwa ukuchonga izinga lokuhlanzeka kwegazi eliqokelelwa kubaxhasi.
Ukulungiselela
Ngaphambi kokwenza utywala usebenzisa indlela ye-PCR, ibhinqa kufuneka lilungiswe. Ngenxa yoko, kuyimfuneko ukugcina imithetho ethile yokuhanjiswa kwe-smear kwi-PCR. Ngoko, inyanga ngaphambi kokuba uthathe izixhobo zokwenza isifundo, nqama ngokupheleleyo ukuthatha imithi, kunye neenkqubo zonyango.
Isampulu sezinto eziphathekayo zenziwa ngaphambi kokuya esikhathini okanye emva kweentsuku ezi-1-4 emva kokupheliswa kwazo. Ebusuku, iintsuku ezingama-2-3, ibhinqa kufuneka libale ukulala ngokwesondo, kwaye xa uthatha izinto ezivela kwi-urethra, - ungabhodi kwiiyure ezingama-2 ngaphambi kokuba wenze inkqubo. Ukuthabatha izinto eziphathekayo kwiintsholongwane, njengomthetho, kwenziwa kwinqanaba lokuxakeka.
Kuqhutywa njani?
Olu hlobo lokufunda, i-smear kwi-PCR, lwenziwa xa i-STI ishintshiwe, kunye ne-HPV kunye nokukhulelwa. Ngaphambi kokwenza i-smear isebenzisa indlela ye-PCR, lo mfazi uqeqeshelwa ukufundisisa, ngokwesi sicwangciso esichazwe ngasentla.
Isampula samatampu kaSam senziwa kwibhubhoratri. Kufuneka kuqatshelwe ukuba ukuba igazi lisetyenziselwa i-PCR, ngoko ucingo luqhutyelwa kwisisu esingenalutho, apho umfazi esilumkisa malunga nangoko.
Izinto eziqokelelweyo zifakwe kwiibhubhu zokuvavanya, apho ziyakuthi zenziwe khona. Isiphumo sophando siyinxalenye ehlanganisiweyo ye-molecule ye-DNA ye-pathogen, apho ichazwa khona. Inkqubo ngokwayo ayithathi ingaphezulu kwemizuzu engama-5, kwaye umphumo wokugqibela uyaziwa kwiintsuku ezingama-2-3. Ngokuhambelana ne-pathogen eyenziweyo, unyango lubekwe.
