Amniocentesis Sensitivity and Specificity
When an abnormal test is presented or when concern that an abnormality is possible in an unborn baby, testing may be necessary. One of the most popular types of testing is amniocentesis.
With this test, doctors will remove a small amount of amniotic fluid from the mother by using a small needle that is placed into the sac through the abdomen. An ultrasound is used to guide the needle into the right location.
This test can look for a number of genetic disorders and is usually performed between weeks 14 and 20 of a pregnancy. The length of time that it takes to get the results back can vary, from a few days to a couple of weeks.
Amniocentesis looks for genetic disorders, neural tube defects and chromosome abnormalities. A couple of the most common disorders that it is used to detect is Trisomy 21 and Down syndrome. It is also something that is sometimes used late in a pregnancy to determine if the baby’s lungs are fully developed yet.
The great thing about amniocentesis is that it has a high sensitivity and specificity rate. This means that it is very accurate. Studies show that this test will offer accurate results 99.4% of the time. This is a great tool for doctors who are looking to care for a baby with a specific disorder.

Be careful when and how you use it
I bought into the hype and broke down and tried this product. After all, how can you resist something that claims that the fat is literally taken out of some of the food that you eat! I must say, though, pay attention to the directions on the package. I used it for a few days with none of the negative effects that many people experience. But during those times I ate fairly healthy meals and nothing too fatty. Then I went out with friends and didn't think about the fact I had taken these pills. I ate chicken wings, blue cheese and french fries. And spent most of the night and a good portion of the next day with several occasions of racing to the bathroom because of digestive issues. I suppose it shows that it does remove "stuff" from your diet because I sometimes have issues going at all and with using this product I went several times a day. But is it worth the risk? Besides, I have no idea if taking the pill was making a difference in my weight loss or if I was having success because I was being more careful in my food choices leading to lower calorie intake.
Weight Loss through Fear of Embarrassment
Was excited to try Alli, heard such great things. Did not see anything for the first couple days I took this. Then came the HORRIBLE side effects. Oily, greasy residue in your underwear and the toilet, and the smell. Oh my gosh. It was awful. Talk about eating healthy - for fear of what this will do to you. Didn't even finish the first bottle it was so terrible.
