I got my vitamin d level checked and it was a 13;should i get other vitamin levels checked as well?

Not necessarily: I find 70% of my patients living in so california where sunshine is a right and not a privilege having vitamin d insufficiency or deficiency. Yours indicates deficiency. Unless you have certain types of anemia , it is not necessary to test for B12 or folate. Make sure that you take some vitamin d3 supplement and recheck the level in 2 months. Vit d3 appears to have many beneficial effects, so.
