Yes, the 24hr PH monitor is just one day in time. We all have varying amounts of reflux throughout the day and throughout the week. It's not all that uncommon to be frustrated by lack of reflux on the one (or 2) days that the monitor is in place. It's frustrating, but a fact of life.
Of course there's always a chance that you can get a follow up test. In my experience, I knew I had reflux that was creating haoc with my lungs, but my first 24hr PH monitor came back extremely low. The second one was quite a bit higher, but still pretty much within the normal range. It took years for the GI doc to agree to send me for a surgical consultation. He was just trying to protect me, but I suffered greatly with very poor lung health until I finally had the surgery.
Don't stress over the test. Just be sure to follow the directions and hope for the best. Worrying about it won't make a difference in the results. Just take the test and let the chips fall where they may.
