I just wanted to point out some very important information on the Maternit21 test. Our genetic counselor (at a large NE teaching hospital) told us that if you get a POSITIVE result, you really only have 70-80 percent chance of having a TRUE positive, which would have to be determined by amnio. This number is based on the actual data they have in the hospital. I find it abhorrent that the company proclaims that the rate of false positive is less than 1 percent, based on one clinical study that they performed several years ago. Real data need to be collected on this exam and the true numbers need to be counseled to patients. The detection rate continues to be high, so if you get a negative, it is pretty reliable. However, if you get a positive, it is not nearly 99 percent accurate.

I'm so relieved, but am still having an amnio on Monday. I think I'll feel really relieved when that is behind me.
