I know a hundred anecdotes can be worth less than an average browse papers, but in its lack of a great search We thought I’d put an anecdote with the comments. We obtained a 93% PPV self-confident having T21 into a beneficial Claritest assessment. Brand new genetics specialist we had been labeled advised all of us brand new PPV is “in fact over 99%” according to an interior Kaiser studies (she indeed failed to admit to cherry-picking data up to We insisted on the seeing personal test outcomes). She required carrying out a NT inspect, then terminating whether it appeared bad. I weren’t delighted toward level of prejudice we had been hearing, therefore wee decided we might generate our choices predicated on invasive tests with high accuracy.
A great CVS shown ~50% unusual structure, and you can just after a really unpleasant waiting an amnio presented fifteen% unpredictable tissues. Without considering beginning yet ,, I am unable to promote one info about just what our very own ultimate result you’ll be. Yet not, I am able to state We have specific biggest inquiries that have how entire state was managed of the our very own medical program, particularly by the genetics counselors exactly who have to have become better taught plus obvious concerning the limits from the NIPS and their very own knowledge of the latest possible consequences.
They were struggling to would meta-analyses away from NIPT for a few sex aneuploidy standards because there was basically very few if any knowledge
I realize your post and.. Omg. Brand new specialist recommended terminating!? Impress! Scientific stability & autonomy- out the windows. Hereditary guidance is supposed to end up being low-directive and aligns certain psychosocial help with so long as you the fresh identified facts. I am thus sorry you’d one to sense! You’re to feel important. The newest CVS was the best choice, however, amnio try top, from the possibility for placental mosaicism. Amnio likewise has a, albeit statistically insignificant, reduced likelihood of fetal losings (whenever complete within the second trimester).
