Tests for Iron Deficiency

If I get regular CBCs, is this enough to tell whether I am anemic? My old GI used to check specifically for Iron and Ferritin in a seperate test, lately I've just been getting CBCs and I feel like my energy level is very low. My GI said my CBCs look good.

Can I have an iron problem if the CBC is all in good range?

You're right. I just looked at my lab orders and they do check iron. I will ask about Vitamin B, I have had D checked and I am deficient.
