To follow on from that, I would slightly disagree with my colleague in that I think pre-symptomatic testing using genomics is still a little bit further away. However, the ability to have very rapid testing once the symptoms onset can help improve outcomes significantly.
In the U.S., a 48-hour genome is becoming a new norm in neonatal intensive care units. When you have a baby who's extremely sick, they will bring a genome. They will do a test. They will try to identify the right therapy within 48 hours. That's instead of trying option one, option two, or option three, during which time the baby is getting progressively worse and during which time there is a deterioration that may not be reparable once the right treatment is identified. With certain seizure disorders, a baby's brain will basically fry before the medicine has the ability to kick in. You need to find the right medicine and you need to find it quickly.
These very rapid testing regimes, which the precision medicine initiatives like the ones suggested are trying to bring to fruit, are the right approach.
