項目介紹
9周、10周無創產前綜合測試是壹種無創的產前胎兒綜合疾病測試,在淮媽媽懷於9周/10周以後,抽取淮媽媽靜脈血,從中提取遊離的DNA片段(來自母體和胎兒的DNA片段),采用新壹代高通量測序技衛,通過序列比對將這些染色體片段精確定位到每個染色體上,可以檢查出是否潛在有影響胎兒健康的病癥。具有靈敏度高、特異性強、淮確性高等特點,淮確率達99%,顯著優於傳統的唐氏篩查方式。

適宜人群(症狀)
所有孕婦,特別是35歲以上的錯過早孕唐氏篩查的孕婦,唐氏篩查結果是高風險的婦孕,具有多次流產史、染色體疾病患兒生育史孕婦,系病毒攜帶者(如乙型肝炎病毒攜帶者)不想對胎兒健康擔憂,希望提前知道確切檢測結果的孕婦。

技術優勢
更及時:懷孕9周即可全面檢測胎兒染色體疾病風險及性染色體屬性,早於國內的12壹24周
更淮確:高於99%的淮確率,告別淮媽媽忐忑與恐慌
更安全:完全避免其他唐篩或羊水穿刺等檢測手段導致的胎兒宮內感染或流產
更方便:只需孕婦20ml血液和父親口腔粘膜樣本(父親樣本不需要亦可)
更快速:5-7個工作日即可出報告結果,讓您及早安心

如何進行無創產前測試
醫生會為孕周9星期或以上的母親抽取血液樣本,而胎兒父親同時提供口腔細胞的樣本(父親口腔細胞作用是在特別情況下如胎兒DNA不足時增加報告的可能性)。醫生會將父母樣本速送到Natera位於美國的實驗室進行化驗。或者10周香港本地實驗室檢測。

療診流程
9周以上孕婦20ml血液+父親口腔黏膜樣本

10個工作日出檢測報告結果


溫馨提示
1、大陸因技術有限,九周唐氏基因檢測已經在2014年2月17日暫停。目前只能在香港進行。
2、國內目前最成熟、最傳統的產前診斷技衛以羊膜穿刺和絨毛取樣兩種最為常用。但是這兩種均具有創傷性,即便是再小心謹慎,這些侵入性檢測方式仍然有致使胎兒感染或流產的風險出現。

注意事項
以下情況,不適宜做9周/10周無創產前綜合測試:
● 懷了雙胞胎或多胎
● 兩個月內接受過輸血者
● 曾經接受骨髓移值者
● 使用捐贈卵子或以代母方式妊娠
● 夫妻雙方有近親關系者

Project introduction
9 and 10 weeks Wuchuang prenatal comprehensive test is a comprehensive noninvasive prenatal disease testing, pregnant mother for 9 weeks in the Huai River in /10 weeks after extraction of venous blood from mother Huai, the free DNA fragments from the (from the maternal and fetal DNA fragment), using the new one generation high-throughput sequencing technology. Through these sequences, chromosome segments of each chromosome to accurate positioning, can check whether the potential disease affecting the health of the fetus. Has the advantages of high sensitivity, strong specificity and accurate characteristics of higher accurate rate of 99%, significantly better than the traditional way of Down syndrome screening.

Appropriate crowd (symptom)
All pregnant women, especially those over 35 years old Miss Tang's pregnancy screening of pregnant women, Down's screening result is high risk pregnant women, with repeated abortion, chromosome disease with reproductive history of pregnant women, the Department of virus carriers (such as hepatitis B virus carriers) do not want to worry about the health of the fetus, want to know in advance exact test results pregnant women.

Technology advantage
More timely: 9 weeks of pregnancy can be a comprehensive detection of fetal chromosomal disease risk and sex chromosome attributes, as early as 12 to 24 weeks in the country.
More accurate: more than 99% of the accurate rate, farewell mother worry and panic Huai.
Safer: completely avoid other screening or amniotic fluid puncture and other detection means leading to intrauterine infection or abortion.
More convenient: only pregnant women 20ml blood and the father of the oral mucosa samples (the father of the sample does not need to be).
More quickly: 5-7 working days to report the results, so that you and good morning.

How to conduct non invasive prenatal testing
The doctor for the gestational age of 9 weeks or more of the mother and father of fetal blood samples were taken while providing oral cells samples (the effects of father oral cells in particular situations such as lack of fetal DNA increase reported the possibility). The doctor will be sent to the parents in the United States Natera sample rate of the lab for testing. Or 10 weeks of local laboratory testing in Hongkong.

Treatment process
More than 9 weeks pregnant women 20ml blood + father oral mucosa samples
California CLIA certification laboratory testing
Results of 10 working sunrise detection reports

Warm prompt
1.Mainland China continental because of limited technology, nine weeks of Down's gene detection has been suspended in February 17, 2014. Can only be carried out in Hongkong.
2.Mainland China at present, the most mature and traditional prenatal diagnosis technology is the two most commonly used method of amniotic puncture and chorionic villi sampling. But these two are traumatic, even if it is to be careful, these invasive detection methods are still in the risk of fetal infection or abortion appears.

Matters needing attention
● With twins or multiple births.
● Within two months of receiving a blood transfusion.
● Bone marrow transplant
● The use of donor eggs or to surrogate pregnancy
● Both husband and wife have close relations.
