I did all the usual blood tests at my booking in appointment three weeks ago. Today I got a letter through saying that "one of the blood tests could not be processed", and asking me to go back to get it re-done.
I know I am being a bit hormonal and mad about this, but I keep worrying that Something Awful has gone wrong. Has anyone else been recalled for a blood test? I can't phone them up and ask what's happened as it's a Saturday. Also, presumably if something really bad had happened, they would have called rather than written?
