Last month I had a 24 hour urine test, so I asked my doctor about the results.
Me: How did my 24-hr urine test look?
Dr. O: This looked good, with no detectable light chains.
Back on 3/24/2003, there was a detectable light chain (lambda), so this is an improvement.
My next appointment will be August 20th. Every month blood is drawn, but the 24 hour urine is done on a less frequent basis. I think maybe every 6 months. It’s an inconvenient, cumbersome procedure. The patient (me, in this case) must collect all urine for a period of 24 hours. The jug is kept refrigerated. In order for the test to be accurate, you must collect it all for the entire 24 hours. Can you imagine how this must be if you’re traveling?
