As long as you have the tubes labeled and in order it's not bad. Just set your timer on your phone every 15 minutes and watch TV or play a game on your phone to pass the time.

The SIBO test with CDi was incredibly user-friendly and easy to complete—it only took about 2 hours and 15 minutes. My results came back very quickly, which made the process even better. I only wish I had done this test two years ago when my symptoms first started. I highly recommend CDI testing to anyone looking for answers quickly.
