downs syndrome 中文意思是什麼
downs syndrome
解釋
染色體21-三體綜合征-
Consequently, an excess number of otherwise normal pregnancies would be recommended to undergo definitive testing to ensure as many downs syndrome fetuses could be detected prenatally. however, conventional definitive genetic testing employs invasive methods, such as amniocentesis to obtain fetal tissue for testing, thus carrying a risk to the fetus
但傳統的基因測試，例如羊膜穿刺術（俗稱抽羊胎水）屬入侵性診斷方法，即是要用針穿過母體進入子宮，抽取胎兒細胞，會為孕婦帶來一定的風險（例如流產） 。 -
Using a novel approach based on the measurement of the ratio of such rna molecules copied from gene copies which the fetus has inherited from the father and mother, professor lo and his team have achieved the noninvasive prenatal detection of downs syndrome
盧煜明教授率領的研究組利用第二十一號染色體其中的一個基因所表達的核糖核酸（ rna ）分子，精密地計算出胎兒由父親及母親遺傳下來的核糖核酸分子的比例，成功進行無創性產前唐氏綜合癥測試。 -

Conventional testing for downs syndrome involves the use of a combination of ultrasound and blood hormone testing to identify pregnancies that should be recommended for further definitive genetic testing
傳統唐氏綜合癥測試包括利用超聲波及血液激素測試，以決定孕婦是否需要繼續進行更詳細及精確的基因檢測。 -

While the current, still experimental test can only be used for a proportion of tested cases, this would already theoretically allow the halving of the number of invasive tests which would be needed for downs syndrome testing
理論上，這種新測試技術已可將傳統的入侵性唐氏綜合癥測試減半。目前這種新方法仍在研究階段，研究人員需不斷改善現有的技術，預計在未來數年可在臨床上廣泛應用。
