PCR mune gynecology (polymerase chain reaction method) ndiyo nzira yekuziva zvirwere zvezvirwere zvezvirwere zvakasiyana-siyana zvinopararira, izvo zvinoenderana nekugadzirisa kwemazwi avo ekutakura kubva kumurwere. Mukuita chidzidzo ichi, nyaya yacho inowanikwa mune imwechete, inonzi "reactor". Sezvo muedzo wokuenzanisa unogona kuita: secretion, ropa, mucus. Zvimwe zvinhu zvinokonzerwa nemakemikari zvinowanikwa kune samuenzaniso yakatorwa. Nekubatsira kwavo, kopi yeDNA yepathogen inogadzirwa. Izvi zvinoshandiswa neketani. Nokuda kweiyo nzira uye ine zita racho.
Inguva ipi inoshandiswa?
Kuongororwa kwehutachiona neCPR inzira yakaoma, kugadziriswa kwemigumisiro inoshandiswa nevanyanzvi. Iyi nzira inobatsira kuziva zvirwere zvakawanda zvakavanzika izvo zvinowanikwa muPCR:
- papillomavirus;
- urogenital (chlamydia, trichomoniasis, ureaplasmosis ).
PCR ndiyo nzira huru yekuongorora hutachiona hweHIV.
Tsanangudzo
Pashure pekuongororwa kwehutachiona uchishandisa nzira yePCR, mhinduro dzekutsvaga dzakagadziriswa. Muchiitiko ichi, maumbirwo maviri anoshandiswa: "mhinduro isina kunaka" uye "chiitiko chakanaka".
Nechikonzero chakanaka, vanachiremba vanogona kutaura nechivimbo kuti kune rimwe kana rimwe rinokonzera causative mumuviri wehurukuro. Mhinduro isina kunaka inoratidza kusakwana kwese kwehutachiwana mumuviri womunhu.
Kubatsira kwePCR
Iyi nzira yekuongororwa ine mikana yakawanda, iyo huru iyo ndeiyi:
- Kutarisa kuongororwa kwekuvapo kwepathogen mumuviri. Dzimwe nzira dzekuongororwa dzinogona kuratidza zviri mukati momuviri wemaproteni-marker chete. PCR inonyatsoratidzawo kuvepo mumuviri wechinhu chinonzi pathogen.
- High degree of specificity. Izvi zvinokonzerwa nekuti mumuenzaniso wezvinhu zvakadzidzwa nechiremba
iyo nzvimbo yeDNA chain ye pathogen inoratidzwa, iyo inozivikanwa. - Kunyanya kunzwisisika kwemuitiro. Nzira yePCR inoita kuti zvive nyore kuona masero ega ega. Iyi pfuma inokosha, sezvo zvirwere zvakawanda zvinokanganisa uye zvine ngozi kune hutano hwevanhu mune nhamba huru chete. Kuonga PCR, utachiona hunogona kusimbiswa pasina kumirira nguva iyo pathogen inowedzera.
- Iko kukwanisa kuitika pamwe chete kuongorora zvirwere zvakasiyana-siyana, kutora samu imwe chete yezvinyorwa.
