There are only two companies out there whose pre-natal DNA blood tests have been shown to be accurate, and definitely several companies that are known to have given false results. If you are going to do a pre-natal DNA test and don't know about the company's reliability, don't waste the money. They are all expensive (if they are charging $1200, they are not one of the reliable ones) and as Mizzz mentioned, none are certified by the courts.
Also adding to the cost, if you are going to get a prenatal DNA blood test, you should test with both men. That way if the test gives wrong results, it is likely to give wrong results for both men and be obviously wrong.

There is a blood test. It's pretty expensive and its nor court certified although one of the companies that offers it is in the process of getting it court certified.
They have a blood one too? I've only heard of doin it like the amino...
Yes there is. It involves a blood test(on the mother-not the baby) and its pretty pricey. Around $1200
Yea.. they stick a needle thru yur stomach nd take out fluid I believe from the baby.. it's called an amino.. they could do many different tests wit an amino... There's risks tho nd costs a lot to do the DNA part
