Explore the impact of gMG on everyday life with the MG-ADL scale

By using the MG-ADL scale at patient visits, you can assess patient improvement and track trends over time.¹

The MG-ADL scale assesses the impact of gMG on daily functions of 8 signs or symptoms that are typically affected in gMG. Each item is assessed on a 4-point scale where a score of 0 represents normal function and a score of 3 represents loss of ability to perform that function. A total score ranges from 0 to 24, with higher scores indicating more impairment.¹
