Ukuba ukhulelwe kwaye unemibuzo malunga notata womntwana wakho okhulayo, usenokuzibuza malunga nokhetho lwakho. Ngaba kufuneka ulinde ukukhulelwa kwakho konke ngaphambi kokuba umisele utata womntwana wakho?

Ngelixa uvavanyo lwasemva kokubeleka lukhetho lukhetho, kukwakho neemvavanyo ezinokwenziwa ngelixa ukhulelwe.

Uvavanyo lwe-DNA luya kugqitywa kwangoko kwiiveki ezili-9 kunye. Ukuqhubela phambili kwetekhnoloji kuthetha ukuba akukho mngcipheko umncinci kumama okanye kusana. Ukuba ukuseka ukuba nguyise yinto ekufuneka uyenzile, nantsi into ekufuneka uyazi malunga nokuthatha uvavanyo lotata ngexesha lokukhulelwa kwakho.

Kutheni le nto kubalulekile ukuba uthathe uvavanyo lukatata ngexesha lokukhulelwa?

Uvavanyo lobuzali lubonisa ubudlelwane bezinto eziphilayo phakathi komntwana notata. Kubalulekile kwizizathu zomthetho, zonyango kunye nezengqondo.

NgokukaMbutho waseMelika okhulelweyo (APA), ogqiba ngoyise:

• iseka izibonelelo zomthetho nezentlalo ezifana nelifa kunye nokhuseleko kwezentlalo
• ibonelela ngembali yezonyango yosana lwakho
• inokuqinisa ubudlelwane phakathi kukatata nomntwana

Ngezi zizathu, uninzi lwase-United States lunemithetho efuna ifom evuma ukuba utata uza kugqitywa esibhedlele emva kokuzalwa kosana.

Nje ukuba ifom igcwaliswe, izibini zinexesha elichongiweyo lokucela uvavanyo lwe-DNA yokuba nguyise kusini na ukuze kwenziwe izilungiso kule fomu. Le fomu ifayilishwe kwiQumrhu leeNkcukacha-manani eziBalulekileyo njengoxwebhu olubophelela ngokusemthethweni.

Uvavanyo lobuzali: Zeziphi iindlela zam?

Uvavanyo lobuzali lunokwenziwa ngexesha okanye emva kokukhulelwa. Uvavanyo lwasemva kokubeleka, okanye olo lwenziwe emva kokuba umntwana ezelwe, lunokugqitywa ngokuqokelelwa kwentambo emva kokubeleka. Kananjalo zinokwenziwa nge-swab ye-cheek okanye isampulu yegazi ethathwe kwilebhu emva kokuba umntwana ephumile esibhedlele.

Ukulinda ukumisela ubuzali kude kube ukuhanjiswa, ngelixa uqinisekisa iziphumo ezichanekileyo, kunokuba nzima kuwe nakutata otyholwayo. Kukho iimvavanyo ezininzi zobuzali ezinokwenziwa ngexesha lokukhulelwa.

Ubunina obungaphambi kokubeleka kokubeleka (NIPP)

Olu vavanyo olungavakaliyo yeyona ndlela ichanekileyo yokuseka ukuba nguyise ngexesha lokukhulelwa. Kubandakanya ukuthatha isampulu yegazi kulowo utyholwayo kunye nomama ukuqhuba uhlalutyo lweseli yomntwana. Iprofayili yemfuza ithelekisa iiseli zomntwana ezingekazalwa ezikhoyo kwigazi likamama kunye nelikayise otyholwayo. Iziphumo zingaphezulu kweepesenti ezingama-99 ezichanekileyo. Uvavanyo luyakwenziwa emva kweveki yesi-8 yokukhulelwa.

Amniocentesis

Phakathi kweeveki ezili-14 ukuya kuma-20 zokukhulelwa kwakho, uvavanyo lwe-amniocentesis lunokwenziwa. Ngokwesiqhelo, olu vavanyo luchaphazelayo lokuchonga lusetyenziselwa ukukhangela ukungasebenzi kakuhle kwetyhubhu ye-neural, ukungaqheleki chromosome, kunye nokuphazamiseka kwemfuza.

Ugqirha wakho uya kusebenzisa inaliti ende, ebhityileyo ukuthatha isampulu ye-amniotic fluid kwisibeleko sakho esiswini sakho. I-DNA eqokelelweyo iya kuthelekiswa nesampulu ye-DNA evela kutata onokubakho. Iziphumo zichanekile ngeepesenti ezingama-99 ekumiseni ubuzali.
I-Amniocentesis inomngcipheko omncinci wokukhulelwa kwesisu, onokubangelwa kukusebenza kwangoko, ukuphuka kwamanzi, okanye usulelo.

Iziphumo ebezingalindelekanga zale nkqubo zingabandakanya:

• ukopha kwilungu lobufazi
• ukuxinana
• ukuvuza kolwelo lwe-amniotic
• Ukucaphuka malunga nendawo yenaliti

Uya kuyidinga imvume kagqirha wakho ukuze ufumane i-amniocenteis eyenzelwe kuphela injongo yovavanyo lukatata.

Isampulu ye-chorionic villus (CVS)

Olu vavanyo lokuchonga lungalusebenzisi lusebenzisa inaliti encinci okanye ityhubhu. Ugqirha wakho uya kuyifaka kwilungu lobufazi nakumlomo wesibeleko. Usebenzisa i-ultrasound njengesikhokelo, ugqirha wakho uya kusebenzisa inaliti okanye ityhubhu ukuqokelela i-chorionic villi, iziqwenga ezincinci zethishu encanyathiselwe eludongeni lwesibeleko.

Esi sihlunu sinokuseka ukuba ngutata kuba i-chorionic villi kunye nosana lwakho olukhulayo banemfuzo efanayo. Isampulu ethathwe ngeCVS iyakuthelekiswa neDNA eqokelelwe kulowo utyholwayo. Kukho iipesenti ezingama-99 ezichanekileyo.

I-CVS inokwenziwa phakathi kweeveki ezili-10 ukuya kwezi-13 zokukhulelwa kwakho. Uya kuyidinga imvume kagqirha xa ugqibile ukuseka ukuba nguyise. Njenge-amniocentesis, iqhele ukusetyenziselwa ukufumanisa ukungaqheleki kwe-chromosome kunye nokunye ukuphazamiseka kwemfuza. Ngelishwa, 1 kwiinkqubo ezili-100 zeCVS ziya kukhokelela ekuphumeni komzimba.

Ngaba umhla wokumitha umisela ukuba nguyise?

Abanye abantu basetyhini bayazibuza ukuba ingaba utata ungasekwa na ngokuzama ukukhomba umhla wokukhulelwa. Kunzima ukumisela ngokuchanekileyo ukuba ukukhulelwa kwenzeka nini kuba uninzi lwabasetyhini luvuthisa ngeentsuku ezahlukeneyo ukusuka kwinyanga enye ukuya kolandelayo. Kwaye, isidoda sinokuhlala emzimbeni kangangeentsuku ezintathu ukuya kwezintlanu emva kokwabelana ngesondo.

Ukuba uye wabelana ngesondo namaqabane amabini ahlukeneyo kwithuba leentsuku ezili-10 omnye komnye ukhulelwe, uvavanyo lukatata kuphela kwendlela yokuchonga ngokuchanekileyo ukuba ngubani oyena tata.

Ixabisa malini uvavanyo katata?

Kuxhomekeka kuhlobo lwenkqubo oyikhethayo, amaxabiso ovavanyo lobunina ahluka phakathi kwamakhulu aliqela kunye namawaka aliqela eedola.

Ngokwesiqhelo, kubiza ixabiso eliphantsi ukuvavanya ukuba unguyise ngaphambi kokuba umntwana azalwe kuba uthintela imali eyongezelelweyo kagqirha kunye nesibhedlele. Unokubuza malunga nezicwangciso zokuhlawula xa ucwangcisa uvavanyo lwakho lobuzali.

Okukwintsusa

Musa ukuthembela kuvavanyo lobuzali nakweyiphi na ilebhu. Umbutho waseMelika okhulelweyo ucebisa ukuba kuvavanywe ukuba ngubani na ovela kubantwana kwiilebhu ezivunyiweyo yiAmerican Association of Blood Banks (AABB). Ezi iilebhu ziye zahlangabezana nemigangatho engqingqwa yokusebenza kovavanyo.

Ungajonga iwebhusayithi ye-AABB uluhlu lweelebhu eziqinisekisiweyo.

Q:

Ngaba bukhona ubungozi bokuthatha uvavanyo lwe-DNA lwe-DNA ngexesha lokukhulelwa?

Isigulana esingaziwayo

A:

Ewe, kukho iingozi ezinxulumene nokuvavanywa kwe-DNA ngexesha lokukhulelwa. Imingcipheko ibandakanya ukuqunjelwa, ukuvuza kwe-amniotic fluid, kunye nokopha kwilungu lobufazi. Umngcipheko omkhulu kubandakanya umngcipheko omncinci wokonzakalisa umntwana kunye nokuphuma kwesisu. Xoxa ngale mngcipheko kunye nogqirha wakho.
