Ukuhlolwa kwe-1 trimester - ukuchazwa kweziphumo

Ukuboniswa kwe-trimester kubonisa ntoni? Olu vavanyo lwe-ultrasound, olukunceda ukucacisa ukuba kukho izifo ze-chromosomal kwizigaba zokuqala zokukhulelwa. Ngeli xesha, abafazi kufuneka bafumane ukuhlolwa kwegazi nge- hCG ne-RAPP-A. Ukuba kuvela ukuba iziphumo zokujonga i-trimester yokuqala zibi (i-ultrasound negazi), oku kubonisa ingozi ephezulu ye-Down's syndrome kumntwana.

Imigangatho yokujonga i-trimester yokuqala kunye nokutolika kwayo

Ngexesha le-ultrasound, ubukhulu bomlomo wesibeleko buya kuhlolwa, okumele lukhulise ngokulinganayo njengoko lukhula. Uviwo luqhutywa ngeveki ye-11 ukuya kwe-12 yokukhulelwa, kwaye i-fold folders should be 1 to 2 mm ngeli xesha. Ngeveki 13, kufuneka ifinyelele ubukhulu be-2-2.8 mm.

Isibini sesibonakaliso somgangatho wokujonga i-trimester yokuqala kukubonakaliswa kwethambo lomzimba. Ukuba ayibonakali ngexesha loviwo, oku kubonisa umngcipheko we-Down syndrome kwi-60-80%, kodwa kuthathwa njengokuba kwi-2% yemfestile enempilo, ayikwazi ukuboniswa ngeli xesha. Kwiiveki ezingama-12 ukuya ku-13 isisindo sobukhulu besithambo samasango si-3 mm.

Kwixesha le-ultrasound kwiiveki ezi-12 ziqikelele ubudala kunye nomhla wokuzalwa komntwana.

Ukuhlolwa kwe-trimester yokuqala-ukucacisa iziphumo zeemvavanyo zegazi

Uhlalutyo lwegazi lwe-beta-hCG kunye ne-RAPP-A lugqithiselwa ngokudlulisa iindleko kwixabiso elithile leMM. Idata efunyenweyo ibonisa ukuba kungabikho kokungaqhelekanga okanye ukungabikho kwabo ngexesha lokukhulelwa. Kodwa le miba inokuchaphazela izinto ezahlukeneyo: ubudala nobukhulu bomama, indlela yokuphila nemikhwa emibi. Ngako oko, ngenxa yempembelelo echanekileyo, yonke idatha ingeniswe kwinkqubo ekhethekileyo yekhompyutha, ingqalelo iimpawu zobuqu zomama ozayo. Iziphumo zengcinezelo yolu cwangciso lubonisa kwisilinganiselo 1:25, 1: 100, 1: 2000, njl. Ukuba uthatha, umzekelo, ukhetho 1:25, esi siphumo sibonisa ukuba ukukhulelwa kwezi zibonisi ezifana neyakho, iintsana ezingama-24 zizalwa ziphilile, kodwa enye yodwa i-Down syndrome.

Emva kokuvavanywa kokuhlolwa kwegazi kwi-trimester yokuqala kunye nesiseko sayo yonke idatha yokugqibela efunyenweyo, i-laboratory inokunika izigqibo ezimbini:

1. Vavanyo oluhle.
2. Vavanyo olubi.

Kwimeko yokuqala, kuya kufuneka ufumane uvavanyo olujulile kunye neemvavanyo ezongezelelweyo . Ngokhetho lwesibini, izifundo ezingaphezulu azidingeki, kwaye unokulindela ngokukhuselekileyo ukuhlola okulandelayo okucwangcisiweyo okwenzeka ngexesha lokukhulelwa ngexesha le-2 trimester.
