Low disease activity

Your BASDAI score is 0 - Low disease activity. A score below 4 suggests your AS is relatively well controlled right now. This doesn't mean you're symptom-free - it means your disease activity is in the lower range. It's still worth tracking this over time and bringing it to your next rheumatologist appointment.

Low activity
< 4
Moderate
4 – 6
