Noninvasive Prenatal Testing.
Noninvasive prenatal testing (NIPT) can help detect certain chromosomal abnormalities in a developing fetus. Most DNA is contained within cells, but a small amount circulates freely in the bloodstream. During pregnancy, a small percentage of cell-free DNA in a woman’s blood is from the placenta and usually matches the DNA of the fetus. With NIPT, cell-free fetal DNA can be examined for evidence of aneuploidy (an extra or missing chromosome). For example, NIPT can be used to look for Down syndrome, which is caused by an extra copy (trisomy) of chromosome 21.
When Is NIPT Used?
Noninvasive prenatal testing is not a routine prenatal test, which means it is not automatically performed during pregnancy. It is usually offered when a pregnant woman has an increased risk of having a child with aneuploidy.
A woman will be aged 35 years or older at the time of delivery
.
A routine prenatal test result is positive for aneuploidy
.
A woman has a history of pregnancy with fetal trisomy
.
An ultrasound shows a fetal abnormality that could be caused by aneuploidy
.
A parent has a history of certain chromosomal abnormalities

#BLACKBOX# #Chanel# Just like how every detail of their jewellery deserves to be noticed, our role in this 11 Days event was to capture guests' precious moments and make them timeless. We caught glimpses of invaluable moments with a photobooth. At the photo booth, guests were free to express themselves and we captured 4 shots as soon as the guests were ready.
After doing so, guests were able to choose their “best” shot on the screen . After selecting, guests were prompted to scan a QR code which led guests to the Chanel Official WeChat account. Guests simply had to follow the account thereby receiving the digital and physical copy

希望是一种坚持，使灵魂深处保有一片自由的天空，为相同的生命做出不同的解释。---《肖申克的救赎》
时间可以吞噬一切,但它丝毫不能减少的是你伟大的思想,你的幽默,你的善良,还有你的勇气。——《小妇人》
My English practice today:
Hope is a kind of persistence, it makes and keeps a free sky within your deep soul, and it provides different interpretations for the same life.
Time is able to erode all things, but it is not able to erode and decrease your mind, your humor, your kindness, and your moral courage.
