I a koe e hapu ana, he mea noa te maha o ngā pātai mō te tamaiti kei roto i tō kōpū. Hei kimi i ngā whakautu ki ētahi o ēnei pātai, ka whakahaerehia e mātou ngā whakamātautau maha (whakamātautau i mua i te whānautanga) i te wā e hapu ana. Nō reira, ko tētahi o ēnei whakamātautau motuhake e kiia ana ko te NIPT. Mā tēnei ka taea e tātou te mōhio mēnā kei te mōrearea tō pēpi ki te whakawhanake i ētahi āhuatanga ira, pērā i te Down syndrome . Heoi, ehara tēnei i te whakamātautau motuhake 100%. Nō reira, ko ētahi tākuta e pai ake ana ki te kī ko te NIPS (tātari) kaua ko te NIPT (whakamātautau). Nā te mea he tohu noa iho tēnei i te mōrearea.
Me pēhea te mahi i te whakamātautau NIPT? He tino māmā!
Kua rongo katoa tātou i te DNA. He rite ki tētahi pukapuka kei roto i ia pūtau o tō tātou tinana, e pupuri ana i ō tātou mōhiohio ira katoa. I mōhio koe kei te rere haere hoki ngā wahi iti o tēnei DNA i roto i ō tātou toto. Ka kiia tēnei he DNA kore-pūtau, he `cfDNA` rānei?
Nō reira, i a koe e hapu ana, kei roto i ō toto tō ake `cfDNA`, me ngā kongakonga o te DNA o tō pēpi (cell-free fetal DNA - cffDNA) . He mea whakamiharo tēnā? Ko te whakamātautau NIPT he tango i tētahi tauira toto māmā mai i a koe, ka whakamātautau mō ngā kongakonga o te DNA o tō pēpi, hei hoatu i ngā tohu mō ētahi āhuatanga ira. Nā te mea he whakamātautau kore-whakaeke, kāore he mōrearea ki a koe, ki tō pēpi rānei.
He aha tā tātou e ako ai i te whakamātautau NIPT?
Ko te whakamātautau NIPT te mea nui hei tirotiro i ngā āhuatanga rerekē o ngā chromosome. He māmā noa iho, he takirua ngā chromosome i roto i ō tātou pūtau. Engari i ētahi wā, hei utu mō ngā tārua e rua o te chromosome, ka toru pea. Ka kiia tēnei he trisomy .
Anei ngā āhuatanga matua o te trisomy e tirohia ana e te whakamātautau NIPT me tōna tika:
| Āhuatanga ira | Tau o te ira-ira (Trisomy) | Te Tika o te NIPT |
|---|---|---|
| Te mate Down | Trisomy 21 | ~99% |
| Te mate Edwards | Trisomy 18 | ~97% |
| Te mate Patau | Trisomy 13 | ~87% |
Kia maumahara: He whakamātautau tirotiro noa iho te NIPT e whakaatu ana mēnā he mōrearea kei roto. Kāore e taea te tino mōhio kei te pāngia tētahi mate.
Mena he pai te hua o te NIPT, arā, he tohu mō te mōrearea, me whakahaere he whakamātautau tātaritanga hei whakaū. E rua ngā whakamātautau e mahia ana mō tēnā:
1. Te whakamātautau ira tangata: He tikanga e tango ana i tētahi tauira o te wai amniotic mai i roto i te kōpū, ka whakamātautau ai.
2. Te Tātaritanga o ngā Korowai o te Pēpi (CVS): He tikanga e tango ana i ētahi pūtau mai i te whenua o te pēpi, ka whakamātautau i aua pūtau.
Nā te mea he whakaekenga kino ēnei whakamātautau e rua ( invasive ), he iti noa te mōrearea. Nō reira, tera pea ētahi whaea e kore e pai ki te mahi i ēnei.
Hei tāpiritanga, ka taea hoki e te NIPT te whakatau i te ira tangata o te pēpi. Ki te kore koe e hiahia ki te mōhio, kaua e wareware ki te kōrero ki tō tākuta i mua i te whakamātautau.
Ko wai e hiahia ana ki te mahi i te whakamātautau NIPT?
Ka taea tēnei whakamātautau e tetahi whaea kua tekau wiki te roa o te hāputanga. Heoi, ehara i te mea he whakamātautau whakahau. Heoi, ko ngā whaea he nui te mōrearea ki ētahi āhuatanga ira ka nui ake te hiahia ki tēnei.
Ko wai kei te mōrearea nui ake?
- Ngā whaea neke atu i te 35 tau te pakeke.
- Ngā whaea kua whānau i mua i tētahi tamaiti me te mate trisomy.
- Ko ngā whaea kua kitea kei te mōrearea rātou mā tētahi atu whakamātautau tirotiro (hei tauira, te tirotiro i te toru marama tuatahi o te hapūtanga).
Ngā āhuatanga kāore pea e tino pono ngā hua NIPT
Ko te whakamātautau NIPT e whakawhirinaki ana ki te nui o te DNA pēpi i roto i te toto o te whaea. He iti noa iho tēnei ōrau, tata ki te 10%-20%. Nō reira, ka pā pea ētahi āhuatanga i roto i te tinana o te whaea ki ēnei hua.
- Mena he 30, he teitei ake rānei tō taupū papatipu tinana (BMI).
- Mena i hapu te tamaiti me te hua manu i tukuna.
- Mena kei te whakamahi koe i ētahi rongoā whakaheke toto.
- Mena he māhanga, he maha atu rānei ngā tamariki kei roto i te kōpū.
I tēnei wā, he pai ake te kōrero ki tō tākuta me te whakatau mēnā he tika te whakamātautau NIPT māu.
He aha tāu e mahi ai i muri i te whiwhinga o ngā hua NIPT?
He mea noa te pouri me te ohorere ina kitea he mōrearea tō hua (he hua pai) mai i te whakamātautau NIPT. Kaua e mataku. Tuatahi, kia mahara ehara tēnei i te whakatau whakamutunga. I tēnei wā, he mea nui kia kōrero koe ki tētahi kaitohutohu ira, ki tō tākuta rānei kia mārama ai koe ki ngā hua.
He whakamātautau tohu mōrearea noa iho te NIPT. Kaua e whakatau i ngā whakatau nui mō tāu tamaiti i runga i taua hua anake.
Ki te hiahia koe, ka taea e koe te whai i tētahi whakamātautau tātaritanga pērā i te `amniocentesis`, `CVS` rānei kua whakahuatia ake nei hei whakaū i te āhuatanga 100%. Mēnā rānei, kei a koe te tika kia kaua e whai i aua whakamātautau. Kōrerohia marietia ki tō tākuta mō ēnei mea katoa.
Karere Tangohia ki te Kāinga
- He whakamātautau NIPT e mahia ana mā te whakamahi i tētahi tauira toto noa i tangohia mai i te whaea hāpu, ā, kāore he mōrearea ki a koe, ki tāu pēpi rānei.
- Ehara tēnei i te tātaritanga tuturu 100%. He whakamātautau tirotiro noa iho tēnei e whakaatu ana i te mōrearea o ngā āhuatanga pēnei i te Down syndrome.
- Mena he pai te hua o te NIPT, me whakahaere tētahi atu whakamātautau, pērā i te amniocentesis, hei whakaū.
- Me kōrero tonu ki tō tākuta mō ngā hua o te NIPT me ngā mahi e whai ake nei, kaua e whakatau i a koe anō.
