Cystic fibrosis diagnosis Tokyo

Hello everyone!

Does anyone know of a hospital where they can test you for cystic fibrosis?

For context: I gave birth almost two months ago and since then, whenever I put my hands in water for too long I get something called Aquadermic wrinkling of the palm, which is something commonly found in people with active CF or carriers of the gene (I thought at first that it was a baby soap allergy as I’d never had this before).

In Europe or the US your baby gets tested at birth as there’s a 1/3000 chance Caucasian people carry the gene. However, in Japan there are currently less than a 100 people with CF and it’s so rare they don’t test babies at the screening test.

My problem is with a disease that’s so rare here, where do I go and take my newborn to get tested? Myself too, obviously, but I’m pretty sure I would have had other and more serious health problems before if I had active CF.

I’ve looked on the internet and called the hospital where my baby was born to no avail, so I know it’s a pretty long shot but maybe some of you wanting to have babies have been tested here and have some info?

Thanks!
