24 Hour Urine Test

[Beccapooh]

Will it still "work" if I'm feeling better? I seem to be feeling somewhat better since my big time flare last summer. I guess I'm worried about yet another test coming back "normal" and having it be a false negative. Will it come back as a positive even if I'm not feeling total crap? Does anyone know?

I would be crushed if it came back negative and was really, actually my problem, (which I believe that it is!!).

I know that y'all aren't doctors, but, has anyone had this test when they were (somewhat and comparably) better than they were? OMG, does any of this make sense? I'm such a nut these days. What I'm trying to say is that I WAS so sick that I could hardly get out of bed and I couldn't speak, etc. Since, then, I've slowly regained some strength and have more energy (which is kinda funny, considering how many naps I take!!) and my point is this...........will the test still come back positive (if it is indeed meant to) even if I'm "BETTER"??

There are several tests requiring a twenty four hour urine. I think it depends upon what kind of solution they put into the container. I have had two twenty four hour urines done. One test looked for some type of adrenal problem and the other was for hepatic porphyria. (this is very very rare but I have it in my family) What are they running the test on you for? I had the same concern as you do. When I had the porphyria testing done, they said it would be best if done during an "attack" as porphyria usually occurs in episodes. I ended up having it done in the hospital. I would talk to your doc and see exactly what this test is checking for because they have to prep it different ways for different things.

Good luck

They ask you to collect your urine in a gallon jug. Ask for a spare. You may need it.

When I had mine, they measured the amount of aldosterone metabolites, by mass spectrometry. Mine were 8 times the upper limit of normal. Guess that pretty much ruled out Addison's disease!
