They got back to me via email within 3 days and sent me containers for storing the milk and kit to get my blood drawn and tested by my gp. They made it sound like they would only accept what I froze in their containers and not my milk bags that I already had in my freezer though.
Also, thank you for being a donor ❤️
Hope they get back to you soon! If you have some you're at risk of binning, you can use some in babies bath, it's great for their skin. You can send some away to make yourself some breastmilk jewellery if you like. I've seen recipes for skin cream using breast milk too.
