Not sure but from experience my blood uric acid levels were high even when I wasn’t having a gout flare up. What I did after having so many flare ups is I went to see a nutritionist because I found too many conflicting food no no’s on the internet. She gave me a gout diet to follow and have not had a flare up since. also my blood uric acid level is now normal
Have they done any X-rays . I wonder myself as I have osteoarthritis, gout which is an arthritis, not sure what other arthritic conditions I might have.
Good luck
