What does it mean if your urine shows up purple on the strip?

If you are using this particular tape....QT-40, it is a sanitizer tape for testing sanitzer solutions, not a ph test tape for urine. If you are using a tape with a 5 to 9 range, then the reading should show the ph reading for your urine test result. Bluish purple is generally a higher alkaline reading on a 5 to 9 or 8 tape, depending on the tape you are using.

What does it mean if the test strip turned bright yellow?

There is not enuff sanitizer in the water

Do these have an expiration date? Any other Chlorine strips I have used in the past expire.

It is an industry best practice to follow the expiration date on test strips; however, in my experience they do seem to be effective well past the expiration date. If you are using these test strips daily, which you should, and you don't keep huge stockpiles, I wouldn't worry about the expiration date. Make sure they stay dry and throw them away if you see any discoloration. This applies to both qt-40 and chlorine test strips.
