This is far from the first case. There was a case related to welfare benefits that ended up with a woman fighting for years to have people believe her baby was hers.

That case involved a maternity test, not a paternity test. It's even mentioned in the article: "A similar case in 2006 saw a 26-year-old chimeric woman, Lydia Fairchild, almost lose her children after maternity tests required for welfare payments suggested she wasn’t actually their mother."

  What's the difference between a paternity test and a maternity test? Will there be a "first case of paternity test fooled by chimerism" for an asian/ a person under 22/ a person with blonde hair?

    Women tend to have reliable first-hand information as to whether they gave birth to a particular child, so maternity tests occur in different social and legal contexts and have different consequences. (Admittedly giving birth to a given child is not the same as being its genetic mother, but in most cases the distinction is not at issue.)

    A maternity test tells you who the genetic mother is. A paternity test tells you who the genetic father is. The legal system sees genetic forensic evidence as very strong. This result shows that we need to be a bit more careful about the samples we used for genetic testing - although this means police procedures for extracting samples are going to get a lot more complicated than a simple cheek swab.

      > A maternity test tells you who the genetic mother is. A paternity test tells you who the genetic father is. Which is, from the point of view of the test, exactly the same thing. However, it's obvious that "mater semper certa est" ("the mother is always certain"). That is, almost always, apparently...

"paternity" == father For a mother, it's called "maternity" Many people who are learning English (as I presume you are) learn the language is genderless, but that's not strictly true. http://dictionary.reference.com/browse/paternity http://dictionary.reference.com/browse/paternity

  No, I'm not learning English. The test is functionally identical. The relation to chimerism is not unique for a father vs a mother. It's just came across as a silly headline to me. I read most of the article and didn't see the reference to the maternity case.
