Basically, I've had pretty regualr and ongoing pain in my lower back for a few years, so I went to my GP to ask for advice. I was referred for physio, and told to have some blood tests.
Well, the results have come back, and three of the four are normal - Full blood count, one for rheumatoid arthritus and one other which I forget.
The fourth one was for "HLAB27" as the receptionist told me, and I have an appointment with my GP in a week to discuss the results of that one. The receptionist wasn't able to tell me more about the result because, as she herself said, she doesn't know what it is. Which is fair enough, only I'm a worrier, and now I have a week's wait to discuss this mystery something.
Before I google and terrify myself, does anyone know an actually plausible thing that it could be? Do I need to be worried, basically, or can I kinda relax a bit?
