I am posting this for future moms who are going to google fish test accuracy vs cvs, error rate, chromosomal test accurace etc. My wife underwent the fish and cvs test due to higher risk age at 36 y/o during pregnancy. We were devastated too when we heard our fish test being positive for XYY or super male chromosomal abnormality. According to the doctor if parents would have had a choice to choose between different abnormal chromosomal abnormalities this is the one to choose due to, it has the most minor disabilities. Still, we were devastated by the results.
We attended different genetic counseling and prepared ourselves for the worse. I stayed sleepless nights trying to research on accuracy of the fish vs cvs test. It states that the fish has a 95% to 99% accuracy and cvs has 99.5% accuracy. This made us more depressed, but made us turn more to God and weep more in prayers.
After 10 days, I received a call from my geneticist stating that congratulations CVS test came out and it is negative. I couldn't believe what I heard and even our genetics Dr. who is head of mount Sinai stated that throughout her career she's never seen conflicting results from both tests, but it can happen. She explains that the chromosomal abnormality can be localized to the placenta.
This doesn't end here my wife was also diagnosed with velamentous cord insertion and had a high AFP which is indicative of spina bifida. After several ultrasound everything is normal and my wife is scheduled to deliver June 25 which is her full term.
I am writing this because i saw multiple postings from different sites that parents who received positive fish tests for xyy, trisomy 21 etc.... opted to terminate their pregnancy without waiting for the CVS. I hope my testimony will give some light and hope to some parents who were in the same boat like us before. Please do not lose hope for behold the power of prayer and faith which cane move mountains. If you have any questions just reply to this postView Thread
