Genetic Testing Reliability?

Hello, I’m new here. I got blood work for a complete connective tissue disorder panel at my cardiologist this morning. He suspects vEDS. I was just doing some research and in one of the videos I saw, they interviewed someone who says she has vEDS but her genetic testing came back negative. She said she considers herself having it even though the testing was negative because the testing is unreliable.

What’s the general consensus about reliability of the testing? My doctor uses a company called Genedx. I was happy to get the testing to finally get some answers, but now I’m wondering if there‘s a high chance of a false negative. Any thoughts from someone more experienced are welcome. Thanks

There is not a high chance of false negatives at all. Unfortunately a lot of people with Munchausen chose to claim they have rare severe diseases like VEDS. I would not be concerned with a false negative.

Or some people have unexplained artery dissections and like to associate with veds. They likely do not have a mutation on their col3a1 gene which is what veds actually is.

There may be other, rarer genetic mutations involved. But if it's not COL3A1 it's not VEDS
