Hey guys, so I'm trying to order a private blood test from blue horizon for the intrinsic factor and I'm a little confused. It may sound like the silliest question but seeing as I'm about to fork out £129 I think i will take the risk and look stupid 🙄
There are 4 options and I'm not sure which 1 to pick:
Vacutainer self arrange
Other sample type.
All comments welcome
