I met a genetic counselor to find out about the Harmony a few weeks ago, the main difference I gathered, is that the Harmony does not test for gender while the Matern21 does.
Other stuff we were told, that the Harmony is 99% accurate at screening only for Downs, the accuracy goes down to about 90% for trisomy 13 and 18. It does not screen for any other chromosomal disorders other than those 3.
thanks for the dialogue. Thought we might offer some insight about the Harmony
Prenatal Test. Clinical research (http://www.ariosadx.com/review-clinical-data/clinical-data/)
has shown that the Harmony Prenatal Test offer more accurate, simple ways of
understanding fetal trisomy risk. The Harmony test provides a personalized
result and takes into account a woman?s age, gestational age as well as other
factors that can be used to better calculate risk. This is different than the
other tests mentioned above that use massively parallel shotgun sequencing, which
is a type of technology method that has some limitations and extra cost (http://www.ariosadx.com/about-the-science/).
The Harmony test has a greater than 99% detection rate for trisomy 21, which
causes Down syndrome, and has a false positive rate of 0.1%, which is lower
than the other two tests mentioned. More information is available about the
Harmony Prenatal Test at http://www.ariosadx.com/for-pregnant-women/.
