If the draw was for B-12 levels, then I would say "yes", they are normal. However, if that was not one of the tests ordered, and you are concerned, I would certainly ask for one.
I see a chiropractor for my headaches and dizziness, usually helps immediately, but, if you are having other issues, then by all means, pursue with your doctor.
Just because you had blood tests, it doesn't mean specific tests such as B12 or other tests were ordered. See your doctor and request more testing.
