Not necessarily - you don't need parents DNA to do those tests.

Also DNA sequencing is one of those areas which experienced incredible cost reduction, much faster than for example general computing power under Moore's law. I.e. it used to be very very expensive. Heck, the first complete human genome sequencing was completed just 16 years ago, and the project took 13 years.

There was a story a few weeks ago of screwup in IVF involving not-father's sperm combined with mother's egg by accident. The resulting child is now unwanted by the couple.

Between that story and TFA, maybe it's time for regulators to step in and force DNA testing as early as possible in the process to positively confirm the match. It already costs an arm and a leg, what's another few hundred dollars to avoid creating black mirror situations.
