Maybe they coincidentally talked about it. Then the girl opened up she needed blood on that date then the guy told her she donated blood to someone in the same hospital that day, too. Then all their statements matched their story.
I used to donate blood. One day I got a phone call from the hospital asking if I could donate for an emergency right now. I lived a block from the hospital, which I assume was why they called me specifically. I unfortunately couldn't do it, because I had recently been abroad, and this disqualified me from donating for a few months.
A lot of the security factors are based on eliminating people with risk factors, since some diseases need to incubate a bit to show up on tests, and I don't think they test every sample for everything either. This is why they ban you from donating blood if you recently traveled, had gay sex, went to the UK during the mad cow disease years, etc.
I'm sure this varies by country, and it may have changed since then anyway, but when I became a donor in Norway about 15 years ago they definitely told me they did more extensive testing when doing the initial vetting and blood sample than they did after I started donating. They definitely did some testing on each donation, like hemoglobin to check if I'd need iron supplements, and probably the usual suspects in terms of disease, but they claimed the initial one was more thorough.
I'm not familiar with the guidelines for Norway so it definitely could be different. In the US is typical for blood from multiple donors to be pooled and all tested in one batch. Any positive well cause them to discard all units from donors in that pool.

I wonder how they found out.
