Kana uri amai vane pamuviri, zvakajairika kuva nemibvunzo yakawanda nezvemwana mudiki ari mudumbu mako. Kuti tiwane mhinduro dzemimwe yemibvunzo iyi, tinoita bvunzo dzakasiyana-siyana (prenatal testing) panguva yekuzvitakura. Saka imwe yebvunzo idzi dzakakosha inonzi NIPT. Izvi zvinogona kutipa ruzivo rwekuti mwana wako ari panjodzi yekuve nemamwe majini here, akadai seDown syndrome . Zvisinei, iyi haisi bvunzo chaiyo ye100%. Saka, vamwe vanachiremba vanosarudza kuidana kuti NIPS (kuongorora) pane NIPT (kuongorora). Nekuti izvi zvinongoratidza njodzi yacho.
Nzira yekuita bvunzo yeNIPT sei? Zviri nyore kwazvo!
Tose takambonzwa nezveDNA. Yakaita sebhuku riri musero rega rega mumuviri wedu, rine ruzivo rwese rwemajini edu. Waizviziva here kuti zvidimbu zvidiki zveDNA iyi zviri kutendererawo muropa redu. Tinoidaidza kuti DNA isina masero, kana kuti `cfDNA`?
Saka kana uine pamuviri, ropa rako rine `cfDNA` yako, pamwe chete nezvidimbu zveDNA yemwana wako (DNA yemwana isina masero - cffDNA) . Hazvishamisi here izvozvo? Kuongororwa kweNIPT kunosanganisira kutora sampuro yeropa kubva kwauri woiedza zvidimbu zveDNA yemwana wako, zvichikupa ruzivo nezvemamwe mamiriro ezvinhu emajini. Sezvo iri bvunzo isingapindi, hapana njodzi kwauri kana kumwana wako.
Chii chatingadzidza kubva kubvunzo yeNIPT?
Kuongororwa kweNIPT kunonyanya kutarisa kusarongeka kwema chromosome. Zvichitaurwa zviri nyore, ma chromosome anowanzo kuuya ari maviri maviri mumasero edu. Asi dzimwe nguva, panzvimbo pemakopi maviri e chromosome, panogona kuva nematatu. Tinodaidza izvi kuti trisomy .
Heano mamiriro makuru e trisomy anotariswa ne NIPT test uye kururama kwawo:
| Mamiriro ezvemajini | Nhamba yechromosome (Trisomy) | Kururama kweNIPT |
|---|---|---|
| Down syndrome | Trisomi 21 | ~99% |
| Chirwere cheEdwards | Trisomi 18 | ~97% |
| Chirwere chePatau | Trisomi 13 | ~87% |
Ndapota yeukai: NIPT ingori bvunzo yekuongorora inoratidza kana paine njodzi. Hazvigone kuva nechokwadi che100% chekuti chirwere chiripo.
Kana mhedzisiro yeNIPT iine hutachiona, zvichireva kuti inoratidza njodzi, tinofanira kuenda kunoongororwa kuti tione kuti chirwere ichi chine njodzi. Kune bvunzo mbiri dzinoitwa pakuita izvozvo:
1. Amniocentesis: Maitiro anosanganisira kutora sampuro yemvura yeamniotic kubva mukati mechibereko woiedza.
2. Kuongororwa kweChorionic Villus Sampling (CVS): Maitiro anosanganisira kutora masero mashoma kubva muplacenta yemwana uye kuaedza.
Nekuti bvunzo idzi dzese dziri mbiri dzinopinda mumuviri ( invasive ), pane njodzi diki. Nokudaro, vamwe vanaamai vanogona kusada kuti dziitwe.
Pamusoro pezvo, NIPT inogonawo kuona kuti mwana ndewerudzii . Kana usingade kuziva, usakanganwa kuudza chiremba wako usati waongororwa.
Ndiani anoda kuita bvunzo yeNIPT?
Bvunzo iyi inogona kuitwa naamai chero vapi zvavo vane mavhiki gumi ekuzvitakura. Zvisinei, haisi bvunzo inosungirwa kuitwa. Zvisinei, vanaamai vari panjodzi huru yekubatwa nezvimwe zvirwere zvemajini ndivo vanofarira zvikuru izvi.
Ndiani ari panjodzi huru?
- Madzimai ane makore anopfuura 35 ekuberekwa.
- Vanaamai vakambobereka mwana ane chirwere chetrisomy.
- Vanaamai vakaonekwa kuti vari panjodzi nekuongororwazve (semuenzaniso kuongororwa kwe trimester yekutanga).
Mamiriro ezvinhu apo mhedzisiro yeNIPT ingave isina kuvimbika zvakanyanya
Kuongororwa kweNIPT kunoenderana nehuwandu hweDNA yemwana muropa raamai. Huwandu uhwu hunowanzova huwandu hushoma, hunenge 10%-20%. Saka, mamwe mamiriro ezvinhu mumuviri waamai anogona kukanganisa mhedzisiro iyi.
- Kana body mass index yako (BMI) iri 30 kana kupfuura.
- Kana mwana akabatirwa zai remupi.
- Kana uchishandisa mimwe mishonga inobvisa ropa.
- Kana wakatakura mapatya kana vana vakawanda mudumbu.
Muchiitiko ichi, zvakanaka kutaura nachiremba wako wosarudza kana bvunzo yeNIPT yakakunakira.
Unoitei mushure mekugamuchira mhedzisiro yeNIPT?
Zvakajairika kunzwa kusuruvara uye kushamisika paunoona kuti une njodzi (mhedzisiro yakanaka) kubva pakuongororwa kweNIPT. Asi usavhunduke. Kutanga, yeuka kuti iyi haisi sarudzo yekupedzisira. Panguva ino, zvakakosha kutaura nenyanzvi yemajini kana chiremba wako kuti unzwisise mhedzisiro yacho.
NIPT ingori bvunzo inoratidza njodzi chete. Usaite sarudzo dzinokosha nezvemwana wako zvichibva pane zvabuda chete.
Kana muchida, munogona kuenda kunoongororwa chirwere sezvakaita `amniocentesis` kana `CVS` yambotaurwa kuti musimbise mamiriro acho 100%. Kana kuti mune kodzero yekusaongororwa izvozvo. Taurai pachena nachiremba wenyu nezvezvinhu izvi zvose.
Mharidzo Yekuenda Nayo Kumba
- NIPT bvunzo inoitwa uchishandisa ropa rakatorwa kubva kuna amai vane pamuviri uye haina njodzi kwauri kana kumwana wako.
- Uku hakusi kuongororwa kwakakwana kwechirwere ichi. Kungori kuongororwa kunoratidza njodzi yezvirwere zvakaita seDown syndrome.
- Kana mhedzisiro yeNIPT ikaonekwa kuti yakanaka, imwe bvunzo, yakaita seamniocentesis, inofanira kuitwa kuti isimbiswe.
- Gara uchikurukura nachiremba wako nezvemigumisiro yeNIPT nematanho anotevera, pane kusarudza wega.
