hi and welcome
re test to indicate ms.. it's sort of the other way around.. ms is a dx of exclusion.. tests are normally done to try to rule out ms.
all the same, you can find out if your bloodwork matches that of a healthy control or an ms patient.
here's some detailed info on nutritional bloodwork for ms:regimens-f22/topic2489.html#p15460
you can choose to be proactive by ensuring all these levels are in tip top optimal shape (as distinct from 'normal')
most of the info at the above link is not yet standard treatment. there's a significant gap btw the existing science on nutritional status in health and disease, and policy/practice.
question: how long will your vit d prescription last? and is it d2 (ergocalciferol) or d3 (cholecalciferol)? i ask b/c the intake is not balanced with other nutrients that are known to be subpar in ms patients.
another question: what else was tested as part of the panel? if you can get a copy of the results we can unpack things that came back 'normal' but might still be suboptimal in a way that correlates with ms (many low nutrient values seen in ms patients are in fact within 'normal' ranges.. just much lower than the levels in healthy controls)
comment: the spasms, anxiety and stress might be linked to a magnesium deficit - magnesium is also low in ms. high dose d3 can interfere with magnesium status over time. particularly if you are already dealing with symptoms of low mag. the link above has info on serum magnesium target levels
i confess to being academically interested in the idea of nutrient testing concurrent with ANA testing.
anyway fire away if you have questions
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
