Correct answer: C — Low disease activity
The correct answer is C, low disease activity. Current ASDAS states are inactive disease below 1.3, low disease activity from 1.3 to below 2.1, high disease activity from 2.1 to 3.5, and very high disease activity above 3.5. An ASDAS-CRP of 1.8 therefore lies within the low-disease-activity interval. “Moderate disease activity” was the former name for this interval and was replaced by “low disease activity” in the updated ASDAS nomenclature. Inactive disease requires a score below 1.3, while high and very high disease activity require substantially higher scores.
