Uma ungumama ozoba nomntwana, udokotela wakho kungenzeka ukuthi ukutshelile ngezivivinyo ezahlukahlukene. Phakathi kwazo, kungenzeka ukuthi uke wezwa ngesivivinyo esibizwa ngokuthi 'i-NIPT'. Omama abaningi bazizwa besaba kancane lapho bezwa leli gama. Imibuzo efana nokuthi 'Kuyini lokhu?', 'Ingabe lokhu kuzolimaza ingane?' ifika engqondweni. Ngakho-ke namuhla, ake sithole izimpendulo ezilula kuyo yonke imibuzo onayo mayelana nalesi sivivinyo se-NIPT.
Kuyini lokhu kuhlolwa kwe-NIPT?
Kalula nje, i-NIPT iwukuhlolwa kokuhlola okuhlola ingozi yokuphazamiseka kwe-chromosome embungwini ngesikhathi sokukhulelwa. Kulula kakhulu. Kwenziwa njengokuhlolwa kwegazi okuvamile, ngokuthatha isampula yegazi engalweni kamama.
Cabanga nje, uma ukhulelwe, igazi lakho liqukethe izingcezu ezincane ze-DNA yomntwana wakho kanye ne-DNA yakho. Lokhu sikubiza ngokuthi "i-DNA engenamaseli (cfDNA)". Ngakho-ke okwenziwa ukuhlolwa kwe-NIPT ukuhlola lezi zingcezu ze-DNA yomntwana wakho kusampula yegazi lakho bese uthola umbono wolwazi lwezakhi zofuzo lomntwana.
Into ebaluleke kakhulu ukuthi lokhu kumane nje kuwukuhlolwa. Lokho kusho ukuthi kukutshela kuphela ukuthi usengozini yesimo esithile. Akusikho ukuxilongwa . Kungakutshela nobulili bomntwana (umfana noma intombazane).
Ukuhlolwa kwe-NIPT kubheka ini?
Lokhu kuhlolwa akukwazi ukuthola zonke izifo zofuzo, kodwa kungasiza ekutholeni ingozi yokuphazamiseka okuningana okuvamile kwe-chromosome.
| Isimo Sihlolwe | Incazelo Elula |
|---|---|
| I-Down syndrome (i-Down syndrome - i-trisomy 21) | Isimo esibangelwa ukuba khona kwekhophi eyengeziwe (ezintathu) ye-chromosome 21 esikhundleni sezimbili. |
| I-Edwards syndrome (i-Edwards syndrome - i-trisomy 18) | Isimo esibangelwa ukuba khona kwama-chromosome amathathu esikhundleni sama-chromosome amabili, 18. |
| I-Patau syndrome (i-trisomy 13) | Isimo esibangelwa ukuba khona kwama-chromosome amathathu esikhundleni sama-chromosome amabili, 13. |
| Izinkinga ze-chromosome yocansi | Ukwehluka kwenani elijwayelekile lama-chromosomes e-X kanye ne-Y. Izibonelo: I-Turner syndrome, i-Klinefelter syndrome. |
Akuzona zonke izivivinyo ze-NIPT ezibheka zonke lezi, ngakho-ke kubalulekile ukukhuluma nodokotela wakho ukuze uthole ukuthi i-NIPT yakho izofunani ngempela.
Kungani kwenziwa lokhu kuhlolwa kwe-NIPT? Kungcono kubani?
Inhloso eyinhloko yalolu vivinyo ukuthola kusengaphambili ukuthi ingane engakazalwa isengozini yesifo esithile sofuzo. Ngaphambilini, lolu vivinyo lwalunconywa kuphela komama abakhulelwe abasengozini enkulu. Okungukuthi:
- Umama oke waba nengane enenkinga ye-chromosome ngaphambili.
- Uma kukhona okungavamile okubonakala enganeni ngesikhathi sokuhlolwa.
- Uma olunye ukuhlolwa kwangaphambilini lubonise noma iyiphi ingozi.
Kodwa-ke, isincomo sakamuva ukuthi noma yimuphi owesifazane okhulelwe ofuna ukwenza lokhu kuhlolwa kufanele anikezwe ithuba lokwenza kanjalo, kungakhathaliseki ukuthi ingozi ingakanani. Lokhu kungokubona kwakho ngokuphelele.
Yisiphi isikhathi esingcono kakhulu sokubhala lesi sivivinyo?
I-NIPT ingenziwa noma nini ngemva kwamasonto ayi-10 okukhulelwa . Ngokuvamile ingenziwa kuze kube yilapho ibelethwa.
Isizathu salokhu ukuthi ayikho i-DNA eyanele egazini lakho ngaphambi kwamasonto ayi-10. Ngakho-ke, kunzima ukuthola umphumela onembile uma ukwenza lokhu ngaphambi kwamasonto ayi-10.
Ukuhlolwa kwe-NIPT kunembe futhi kuphephile kangakanani?
Ukunemba
Ukunemba kwalokhu kuphakeme kakhulu. Kunembile kakhulu ekutholeni i-Down syndrome, ngokunemba okucishe kube ngu-99% . Kwezinye izimo, ukunemba kungaba phansi kancane. Kodwa-ke, uma kuqhathaniswa nezinye izivivinyo zokukhulelwa (isb. isikrini se-quad), amathuba okuba nemiphumela engalungile evela ekuhlolweni kwe-NIPT aphansi kakhulu.
Ukuphepha
Lena yinkinga enkulu kunazo zonke omama abaningi abanayo.
Lokhu kuhlolwa akubeki ingozi enganeni.Lokhu kuphephile ngokuphelele ngoba kwenziwa ngegazi likamama kuphela. Akumthinti umntwana nganoma iyiphi indlela.
Ithini imiphumela?
Ngokuvamile kuthatha cishe amasonto amabili ukuthola imiphumela. Uma uthola imiphumela, bazosho into efana nale:
- Ingozi Ephansi / Embi: Lokhu kusho ukuthi ingane yakho inethuba eliphansi kakhulu lokuthola izimo ezihlolwe.
- Ingozi Ephakeme / Enhle: Lokhu kusho ukuthi ingane yakho ingaba nethuba elithile lokuthola esinye noma ngaphezulu sezimo ezihlolwe.
Umphumela "wengozi ephezulu" awusho ukuthi ingane inalesi sifo nakanjani. Usho nje ukuthi kukhona ingozi nokuthi kudingeka ukuhlolwa okwengeziwe ukuqinisekisa ukuthi lesi sifo sikhona noma cha.
Uma ingozi iphezulu, yini oyenzayo ngokulandelayo?
Uma kunjalo, udokotela wakho uzoncoma ukuhlolwa kokuxilonga okuzokunikeza impendulo eqinisekile ethi "yebo" noma "cha" .
- I-Amniocentesis: Ukuhlolwa okuthatha inani elincane loketshezi (i-amniotic fluid) oluzungeze umntwana. Lokhu ngokuvamile kungenziwa ngemva kwamasonto ayi-15.
- Ukusampula Kwe-Chorionic Villus (CVS): Ukuhlolwa okuthatha isampula encane kakhulu yamaseli avela ku-placenta yomntwana. Lokhu kuvame ukwenziwa phakathi kwamasonto ayi-10 kuya kwangu-13.
Udokotela wakho uzokutshela okwengeziwe ngalezi zivivinyo.
Unquma kanjani ukuthi uzobhala lolu vivinyo noma cha?
Akukho sibopho sokwenza lokhu kuhlolwa. Lesi yisinqumo somuntu siqu ngokuphelele kuwe nomndeni wakho. Ukuze sikusize wenze leso sinqumo, zibuze le mibuzo:
- Bengingazizwa kanjani uma ukuhlolwa okufana nalokhu kungabuya nomphumela "oyingozi"?
- Uma kunjalo, ngingavuma yini ukwenza ukuhlolwa kokuqinisekisa okufana ne-'Amniocentesis' noma i-'CVS'?
- Uma ngithola kusenesikhathi ukuthi ingane yami inesifo sofuzo, ingabe lokho kuzothinta izinqumo zami?
- Ingabe ukwazi lolu lwazi kuzongenza ngizizwe ngidabukile noma ngikhathazekile? Noma kuzongisiza yini ngilungiselele ngokwengqondo nangokomzimba ukunakekela umntwana?
- Ingabe ukwazi lezi zinto kusenesikhathi kuzosiza odokotela ukuthi banakekele kahle umntwana ngemva kokubeletha?
Ngezimpendulo ozinikezayo kule mibuzo, khuluma nodokotela wakho ngokukhululekile bese wenza isinqumo esingcono kakhulu.
Umlayezo Wokuya Nawe Ekhaya
- I-NIPT iwukuhlolwa okuphephile kakhulu okwenziwa egazini likamama okhulelwe futhi akulimazi ingane.
- Lokhu kumayelana nengozi yezimo zofuzo ezifana ne-Down syndrome. Akuyona into yokugcina etholakala ukuthi inesifo.
- Lokhu kuhlolwa kungenziwa nganoma yisiphi isikhathi ngemva kwamasonto ayi-10 okukhulelwa.
- Ungakhathazeki uma umphumela uthi "Ingozi Ephakeme." Kusho ukuthi kudingeka ukuhlolwa okwengeziwe ukuqinisekisa lesi sifo.
- Ukuthi ukhetha ukwenza lokhu kuhlolwa noma cha kuyisinqumo sakho siqu ngokuphelele. Xoxa nganoma yimiphi imibuzo noma ukukhathazeka ongase ube nakho nodokotela wakho.
