Daim Duab: Amniocentesis (Amniotic Fluid Test)

Amniocentesis yog qhov sim uas tuaj yeem ua rau thaum cev xeeb tub los saib qee yam teeb meem hauv kev loj hlob ntawm tus menyuam. Cov teeb meem no suav nrog:

  • Kev yug los ua neeg tsis huv
  • Cov caj ces muaj teeb meem
  • Kab mob
  • Lub ntsws kev loj hlob

Amniocentesis tshem tawm qee qhov kua tawm ntawm lub hnab ib puag ncig tus menyuam hauv plab (tsev menyuam). Feem ntau nws ua nyob hauv kws kho mob qhov chaw haujlwm lossis chaw kho mob. Koj tsis tas yuav nyob hauv tsev kho mob.

Koj yuav muaj kev xeeb menyuam ua ntej. Qhov no pab koj tus kws kho mob saib seb tus menyuam nyob hauv koj lub tsev menyuam.

Cov tshuaj tsau rau tom qab ntawv raug muab txhuam ua ib feem ntawm koj lub plab. Qee zaum, cov tshuaj tau muab los ntawm kev txhaj tshuaj rau ntawm daim tawv nqaij ntawm lub plab. Daim tawv nqaij yog ntxuav nrog kua ua kua tsis huv.

Koj tus kws kho mob muab ib rab koob ntev ntev mus rau hauv koj lub plab thiab hauv koj lub tsev menyuam. Cov kua dej me me (li 4 teaspoons lossis 20 millilitres) tshem tawm ntawm lub hnab uas nyob ib puag ncig tus menyuam. Feem ntau, cov menyuam yuav raug saib xyuas los ntawm ultrasound thaum tus txheej txheem.


Cov kua dej yog xa mus rau qhov chaw kuaj ntshav. Kev xeem yuav yog:

  • Kev tshawb fawb caj ces
  • Kev ntsuas ntawm alpha-fetoprotein (AFP) qib (ib yam khoom uas tsim hauv lub siab ntawm kev loj hlob ntawm tus menyuam)
  • Kab lis kev cai kis kab mob

Cov txiaj ntsig ntawm kev kuaj ntsuas caj ces feem ntau siv sijhawm ntev li 2 lub lis piam. Lwm qhov kev ntsuam xyuas tau rov qab los hauv 1 txog 3 hnub.

Qee zaum amniocentesis tseem siv tau tom qab cev xeeb tub mus rau:

  • Kev kuaj mob kis tau
  • Kuaj xyuas tus menyuam lub ntsws puas tau tsim kho thiab npaj txhij rau kev xa menyuam
  • Tshem tawm cov kua dej tawm ntawm cov me nyuam ib puag ncig yog tias muaj kua dej amniotic ntau dhau (polyhydramnios)

Koj lub zais zis yuav xav tau tas nrho rau ntawm ultrasound. Nrog koj tus kws khomob tham txog qhov no.

Ua ntej kev sim mob, ntshav yuav raug coj mus nrhiav kom paub koj cov ntshav thiab hom Rh. Tej zaum koj yuav tau txhaj tshuaj uas yog hu ua Rho (D) Kev Txhaj Tshuaj Tiv Thaiv Kab Mob (RhoGAM thiab lwm hom) yog tias koj tsis pom Rh.

Amniocentesis feem ntau yog muab rau cov poj niam uas muaj qhov pheej hmoo muaj menyuam uas muaj lub cev tsis xws luag. Qhov no suav nrog cov poj niam uas:


  • Yuav hnub nyoog 35 lossis laus dua thaum lawv yug me nyuam
  • Tau kuaj ntsuas pom tias muaj teeb meem yug los yog muaj teeb meem lwm yam
  • Tau muaj menyuam muaj lub cev tsis xws plab hauv lwm lub sijhawm muaj menyuam
  • Muaj ib tse neeg muaj keeb kwm muaj caj ces cuam tshuam

Kev tawm tswv yim rau caj ces tau raug pom zoo ua ntej cov txheej txheem. Qhov no yuav tso cai rau koj:

  • Kawm paub txog lwm yam kev sim ua ntej yug
  • Ua kev txiav txim siab paub txog cov kev xaiv ua qhov kev kuaj mob ua ntej

Qhov ntsuas no:

  • Yog qhov kev kuaj mob, tsis tas kuaj kev kuaj
  • Yog qhov tseeb heev rau kev kuaj mob syndrome
  • Feem ntau tau ua tiav ntawm 15 txog 20 lub lis piam, tab sis tuaj yeem ua tau thaum lub sijhawm twg nyob ntawm 15 txog 40 lub lis piam

Amniocentesis tuaj yeem siv los kuaj ntau yam teeb meem gene thiab cov keeb neeg keeb nyob hauv tus menyuam, suav nrog:

  • Anencephaly (thaum tus menyuam ploj ib feem ntawm lub paj hlwb loj)
  • Mob ntsws qis
  • Cov khoom noj tsis txaus siab ntawm cov khoom noj uas ua dhau ntawm tsev neeg
  • Lwm cov teeb meem caj, xws li trisomy 18
  • Cov kab mob hauv cov kua dej amniotic

Qhov txiaj ntsig ib txwm txhais tau tias:


  • Tsis pom muaj cov teeb meem keeb lossis caj ceg hauv koj tus menyuam.
  • Qib Bilirubin thiab alpha-fetoprotein tshwm sim li qub.
  • Tsis muaj cov cim qhia tias muaj tus kab mob.

Nco tseg: Amniocentesis feem ntau yog qhov kev ntsuas tau tseeb tshaj plaws rau kev mob caj ces thiab malformation, Txawm hais tias tsis tshua muaj, tus menyuam tseem yuav muaj caj lossis lwm yam mob yug los, txawm tias amniocentesis tshwm sim zoo.

Qhov tshwm sim txawv txav txhais tau tias koj tus menyuam muaj:

  • Cov teeb meem thaum yug uas cuam tshuam txog tus txha caj qaum lossis lub hlwb, xws li tus txha caj qaum (spina bifida)

Tham nrog koj tus kws kho mob txog cov ntsiab lus ntawm koj cov kev kuaj sim. Nug koj tus kws khomob:

  • Yuav kho cov mob lossis qhov tsis zoo li cas thaum lub sijhawm lossis tom qab koj cev xeeb tub
  • Yam dab tsi xav tau tshwj xeeb koj tus menyuam yuav tsum muaj tom qab yug
  • Lwm txoj kev xaiv uas koj muaj txog kev tswj hwm lossis xaus koj lub cev xeeb tub

Kev phom sij muaj tsawg heev, tabsis suav nrog:

  • Kev kis mob lossis raug mob rau tus menyuam
  • Kev Txij Nkawm
  • Kev nqus dej ntawm amniotic kua
  • Vaginal los ntshav
