唐篩結(jié)果高風(fēng)險(xiǎn)怎么辦？

唐氏篩查，是孕中期基本所有女性都會做的一項(xiàng)針對胎兒先天性神經(jīng)管缺陷，和18，21三體綜合征的篩查。很多人看到結(jié)果出現(xiàn)了高危。嚇得大驚失色，那么，唐篩高危寶寶就一定有問題嗎？

不是的。檢查出唐氏篩查高風(fēng)險(xiǎn)，僅僅代表著胎兒患有唐氏綜合征的風(fēng)險(xiǎn)處于截?cái)嘀瞪戏?，也就是可能性更大一些，唐氏篩查只是初步篩查，并非就是確診了，所以千萬不要太緊張。

如果是高齡產(chǎn)婦，唐氏篩查高危的可能性更大一些，因?yàn)樵谟?jì)算風(fēng)險(xiǎn)值的時(shí)候，年齡是計(jì)算的影響因素之一。如果發(fā)現(xiàn)自己的唐篩結(jié)果是高危，那么我們可以考慮進(jìn)行進(jìn)一步的檢查，無創(chuàng)DNA或者羊水穿刺。

無創(chuàng)DNA是通過抽取孕婦的靜脈血，來收集胎兒的游離DNA，這樣就可以更加準(zhǔn)確地檢查出胎兒的18.21.13染色體是否存在異常。而羊水穿刺顧名思義就是抽取羊水，用一根細(xì)長的針頭在b超的引導(dǎo)下進(jìn)入到羊膜腔，抽取20毫升羊水來分離胎兒的DNA，相對來說，結(jié)果更全面也更準(zhǔn)確，但是因?yàn)槭怯袆?chuàng)檢查，存在有一定的感染和流產(chǎn)風(fēng)險(xiǎn)，所以目前沒有無創(chuàng)更普及。

唐篩結(jié)果高風(fēng)險(xiǎn)怎么辦？

你好，非常高興為你解答問題，檢查出唐篩高風(fēng)險(xiǎn)，那就要做無創(chuàng)DNA產(chǎn)前檢測或羊水穿刺了，這兩種檢查的結(jié)果相對穩(wěn)定。因?yàn)檠蛩┐淌菣z查胎兒脫落細(xì)胞，無創(chuàng)DNA檢測是檢測母血中胎兒的DNA。這些硬指標(biāo)是不會改變的。但很多時(shí)候，唐篩是高風(fēng)險(xiǎn)，往往大部分胎兒也是正常的，所以即使唐篩高風(fēng)險(xiǎn)也不要太緊張，聽醫(yī)生的的安排看是否需要進(jìn)一步檢查。

關(guān)于進(jìn)行唐氏篩查，這種篩查是通過檢測母體血清中甲型胎兒蛋白、絨毛促性腺激素和游離雌三醇的濃度，結(jié)合**的時(shí)間、孕婦的體重、年齡等，計(jì)算出生先天缺陷胎兒的危險(xiǎn)系數(shù)，來判斷胎兒患有唐氏癥的危險(xiǎn)程度。一般做唐篩就是在**16--18周進(jìn)行抽血檢查，結(jié)合年齡及其它的因素分析胎兒可能是唐氏兒的可能性，也就是檢查胎兒可能是先天性愚性的可能，唐篩的準(zhǔn)確率一般在50－70%左右。

只個(gè)篩查準(zhǔn)確率確實(shí)低了一點(diǎn)，所以經(jīng)常有孕媽唐篩高風(fēng)險(xiǎn)后來羊穿結(jié)果寶寶是正常的。

你不要大緊張，配合醫(yī)生進(jìn)一步檢查，祝福你和寶寶健康平安！

希望我的回答能夠幫助到你！
