Hi lovely bees!
I was looking to the Harmony / Verifi / MaterniT21 tests to determine the gender of my little bean at 10 weeks rather than waiting till 20 weeks to find out via ultrasound. If you haven’t heard of these tests, in brief, they are blood tests – by 10 weeks of pregnancy, there are little fragments of baby DNA circulating in your blood. If babe is a boy, there will be Y chromosome bits in your blood, which obviously wouldn’t be there otherwise. These tests look for the Y chromosome – if it’s there, you’re having a boy, no Y and it’s a girl. They claim an accuracy of ~98% for gender determination. The three tests above also test for trisomy 21, 18, and 13 with high accuracy.
“Fabulous! I’ll do one of those!”, I thought. Then I realized my insurance only covers this type of genetic screening for “at risk” women – those over 35 for example. Being 30, my insurance only covers the typical quad screen and NT scan. Out of pocket, the cost is about $500 for Verifi and MaterniT21, and $800 for Harmony. Worth it to satisfy my impatience? Probably not.
THEN, today during my daily google time, I came across the same type of test done by a company called Viaguard and you can order only the gender test at a cost of $99 from amazon. Yes, you order it on amazon. Skeptic? So was I. The website looks legit though…
I tried looking for the scientific paper citing the 98% accuracy statement, but couldn’t find it. Anecdotal reports from women who had done the test seem to back up their claim. The only inaccurate result report I found was back when the test was done on a drop of blood submitted on a piece of paper, while they’ve now switched to the more accurate method of testing done on a vial of blood you have drawn at a local lab. It sounds like the test is identical to that done with the harmony/verifi/materniT21 screenings, which makes me think this company is for real.
So, after that long ramble, my question to the bees is – have you done the Viaguard Jack or Jill test? Was it correct? Should we all sacrifice $100 each to have a Weddingbee-based study on it’s accuracy and report it in some journal with our usernames listed as authors?
