Kusvika iye zvino, nzira yePCR (polymerase chain reaction) ndiyo imwe yenzira dzakadzidza uye dzakarurama kupfuura dzose dzokugadzirisa utachiona mumuviri womunhu. Mukuenzanisa nezvimwe zvinongororwa, hazvina kukanganisa, izvo zvinobvumira kuona DNA yeAIDS inotapukira uye yakasikwa.
PCR ndiyo nheyo yeyo nzira
Chinokosha chemuitiro ndechekuona uye nekuwedzera kuwedzera DNA chikamu chepathogen mune zvinyorwa zvehupenyu zvakagadzirirwa kudzidza. Kutakura, kuongorora mashekeri nemaitiro ePCR, unogona kusarudza nyore nyore chero DNA uye RNA ye microorganisms. Sezvo rimwe nerimwe razvo rakave rakasiyana nerinoti genetic detector, iyo, kana chidimbu chakafanana chinowanika mune shanduro yezvinyorwa, inotanga nzira yekuumba nhamba yakawanda yemakopi. Panyaya iyi, kunyatsoshandiswa kwenzira yacho kunosimbisa mhinduro yakarurama, kunyange kana imwe DNA chikamu chetachiona ichiwanika mumuenzaniso.
Mukuwedzera, kuongororwa kwemakemikari uchishandisa nzira yePCR uye kuongorora kwayo kunotevera kunosanganisa kuonekwa kwehutachiona hunopfurikidza kunyange munguva yekudzivirira, apo kliniki zviratidzo zvechirwere hazvipo.
Chinhu chakakosha zvikuru chekutungamira PCR ndechokutanga kugadzirira uye kunyatsotaridzika kwemashoko acho.
Nzira yePCR - inotorwa sei?
Chimwe chezvakakosha zvakakosha zveyo nzira ndeyekuti zvakasiyana zvakasiyana siyana zvebhaibheri zvinokodzera kudzidza. Iyo inogona kunge yakasununguka kumudzimai , smears kubva mumuviri wechibereko kana urethra, urini kana ropa. Chinhu chose chinoenderana nechinonzi pathogen uye nzvimbo yayo.
Kazhinji, kugadzirisa zvirwere zvepabonde uchishandisa nzira yePCR, kuvharwa kwebonde kunotorwa kuti kuone kuti chirwere chetachiona hepatitis C kana HIV chinotorwa neropa rekuenzanisa.
Chero zvazvingava, vanachiremba vanokurudzira vasati vapa nyaya yekuongorora:
- Mazuva matatu tisati tatarisira zuva rekuunganidza zvinhu kuti tisaita zvepabonde;
- nguva isati yatanga kuzvipira, hapana chinhu chiri mangwanani;
- muna manheru, kwete kushamba ne soda antibacterial , asi mangwanani chete nemvura, kwete douche;
- 2-3 maawa asati aedzwa, usashamba;
- Zvakanakisisa kutungamira mutsva pakarepo mushure mekupera kwekuenda kumwedzi.
Zvinonyatsojeka kuti PCR inovimbisa uye inyanzvi yekutsvakurudza nzira, nyore kushandisa, uye inewo zviratidzo zvekunzwisisa. Mukuwedzera pamishonga inoshanda, iyo polymerase chain reaction inoshandiswa mune zvesayenzi.
