Yes, this would be a great test. We should get baseline cT1 and PDFF tests to insure that all patients treated with LL have NAS of 4 or higher. That would be severe NAFLD and all of NASH and even cirrhosis. Then every 3 months, (12 weeks), do 2 simple and very common labs, 1) Comprehensive Metabolic Panel and 2) Thyroid Function Test.
A) When both the Potassium fails to increase from the previous measurement and the

Free Thyroxine T4 fails to increase from the previous measurement, then LL may be stopped, because when both of these conditions are met, LL no longer works for this patient.
Look at the heat map for my reasoning as to why I chose Potassium and T4, (Free Thyroxine).
