Blood tests (those like MaterniT21) are gaining interest. They’re generally considered 95 – 98% accurate at 9 – 10 weeks of pregnancy.
Have you used one? Was it accurate for you? I figure it would just be interesting to hear some anecdotes about this emerging technology.
Many of these tests are marketed for detecting chromosomal abnormalities – like Downs, hemophilia, etc., though gender is obviously the biggest perk for a wider portion of their clients.

I didn’t do it, but I know people who have and they were all accurate.

There is someone in the Jan board who had it done and accurate. I believe you can’t get it done just to find out gender, but it has to be due to medical issues, being over 35 or high genetic history of chromosonal issues. I had one done due to a postive DS test and asked to not check for gender.

@aliciapdx: I have found one or two that will do it without a physician, though you’re correct in that many (like MaterniT21) do require a physician before you can use it.

It’s an FDA-approved test. They have to use large sample pools. It will be accurate for 95-98 women out of 100 if that is what they are espousing. So, for 2-5 women/100 it’ll be wrong.

@CookieCreamCakes: I did the test. It said boy, I was around 10 weeks I think and he seems to be a boy so far from ultrasounds. I’ll let you know for sure in about 4 weeks. 🙂

You can still get it done without a medical reason but then it won’t be covered by your insurance. In the US I think the test runs about $250. We almost did it but I decided it would be more fun for us to find out the gender together in the ultrasound room instead of me getting a phone call at work and having to keep cool til I got home from work to tell Darling Husband or blurting it out to him over the phone. I imagine the accuracy reported for the test isn’t just gender accuracy but also the accuracy of determining the risk for down’s syndrome and others the test is really meant for. From my understanding though, the gender should be extremely accurate since they look at the baby’s chromosomes. Pretty hard to mess that up I would think, not like misinterpreting an ultrasound.

@CookieCreamCakes: I had the MaterniT21 & it was accurate for gender. It is looking at chromosomes so either the Y is there or it isn’t- can’t mess that up. The main reason for the test is to look for the major trisomies- 13, 18 & 21 (downs). Gender is a secondary benefit. It does not look for hemophilia tho.
It is an expensive test. The company subsidizes the cost so if you have a copay it shouldn’t be more than $250. Paying out of pocket would be a couple thousand I think.
