hi there sorry i did not see this til end of day monday!
for starters, you can ask for serum b12, serum vitamin d3 [ ask for 25(OH)D3 metabolite specifically), serum zinc, serum magnesium, and serum uric acid. that should make a good starting point.
your levels will probably all come back 'normal' but they will likely fit a typical ms profile within the normal range. once you know where you stand you can aim to make changes so that you match a 'healthy control' profile.
sorry this did not get to you before your appointment
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
