Boy or girl? A DNA test sold over the web can tell you…

Make 629
DNA worldwide can print your genetic code on your shirt, help figure out who’s related to who and they claim they can tell a new Mother if their kid is a boy or a girl 6 weeks in…

Once a woman has taken the test, she sends her sample directly to the company’s laboratory for analysis and will receive the result in the post or can access it online using a protected password.

The test looks for DNA from the baby in the mother’s blood. If it picks up a Y-chromosome, that means a baby boy can be “confidently” predicted.

If there is no Y-chromosome DNA, the company can state “with equal confidence” that the baby will be a girl, the company says.

  1. My wife an I recently found out that we’re going to have a baby, and had seen something talking about this last week. Now she’s a PhD student in microbiology, and tells me that this kit is just doing a PCR reaction with a simple set of primers that are, like the article states, trying to amplify DNA from a Y chromasome. She says that the primers themselves would cost about $16 from a lab supply company. Now I’m thinking that with the $10 PCR kit described earlier in the month, you could put together this test kit for under $30 and do it all in your own home and get your results in under an hour. (if the other article is correct about it’s processing time for the PCR)

  2. Presence or absence of a Y chromosome doesn’t tell the whole story, as there’s more genetic sexes than XX and XY. Turner’s syndrome, Kleinfeldter’s syndrome, androgen-insensitive XY, etc.
