Why is DNA testing not a mandatory part of the process? I thought embryonic genetic testing for show-stopping diseases was one of the major selling points of IVF. Would that not immediately set off alarm bells for paternity/maternity mismatch?
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.
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.
