CAC tests, yes. I have tested Vitamin D (25-hydroxy) and I was low but I am skeptical of the tests overall value. People that have, or are recovering out of metabolic syndrome need more than those who are otherwise healthy. 25-hydroxy still has to be converted by the kidneys to 1 alpha hydroxylase. I have not found a lab that will test for this yet.
