@m04 @salad_bar_breath Yes, I did. It was mostly a matter of being persistence enough to get the paperwork and reminding everyone on the day off that I wanted them back.
The pathology lab diced them first (looking for cancer, I guess?), and I wish they hadn't. 😡
Some hospitals have policies forbidding this.
A nice trans women who collected "wet specimens" as a hobby gave me advice on how to transport them internationally.
In the end, they were in my carry on bag when I flew home.
