That the blood test that detects down syndrome was positive !
The doctor wants me to get another test done but iam really scare don't know
If I should ?
The maternal blood screen for Down's doesn't test to see if baby has Down syndrome. It is a screening to identify moms who have a higher chance of carrying a baby with Down syndrome.
You don't have to get any more testing if you don't want to, especially if you would be ok with raising a child with Down's. It's mainly a CYA on your doctor's part.
And since this is MDC, I'm going to take this opportunity to point out that, if you have midwives in your area, you might get better prenatal care if you were seeing a midwife. We take the time to explain the tests to our clients and what the results mean.
There actually are two blood tests to evaluate the possibility of DS, as well as other chromosomal issues. The first, or screening, test gives you a ratio (like Rrrrachel mentioned) based on your age. For example, the average risk of DS in a woman my age is 1 in 35. The result of my blood test put me at 1 in 18, or an elevated risk.
But I was able to do a second, more diagnostic, blood test. This determined with a 99% accuracy, that the baby does not have DS.
I wonder if this is a new test that isn't offered widely because I don't think I've seen it mentioned here on MDC.
