Help with blood test results - any ideas?

[Lotus266012]

Hi I don't know where else to put this question but this is something I've noticed in my recent blood test results.

I had a full blood count done and looking at the result for serum alkaline phosphatase it says 66 and then UNKNOWN.

I had my TSH done at the same time and this says 0.69 UNKNOWN and a second TSH done 3 months later that says 22 UNKNOWN.

What does the unknown mean? Does that mean that the doctors don't know why the results are like that? All the other things I've been tested for don't have UNKNOWN by them. I understand my TSH on the second time is quite high and I'm currently on thyroxine for that but I've read up that my alkaline phosphatase result is within the normal range. Should I be concerned about that?

Thanks x

Hi guys, thanks for the input. It just seemed a bit strange to me. Come to think of it the lab has a set range for TSH but that's come up as UNKNOWN. Ah well, probably nothing to worry about. The clinic I go to has changed their computer systems so I don't think I'll be seeing any more of the UNKNOWNs again!!

Thanks x

it probably means the lab doesn't have a set normal range

I agree with mkh9 I think it's a glitch in the printing of the lab results. This is what you pay the doctor for :).

I have worked in the lab for many years (in various labs) and haven't seen that. I guess I would ask your doctor or call the nurse on the phone. It may just be a glitch on the lab printout.
