could you please look at my lab results

[Guest guest]

test name=result unit (reference interval)

IRON & TIBC

Iron (TIBC)=285 ug/dl (250-450)

UIBC=229 ug/dl( 150-375)

Iron, Serum=56 ug/dl (35-155)

Iron Saturation=20 %( 15-55)

FERRITIN, SERUM=34 ng/mL(13-150)

THYROID PEROXIDASE(TPO)Ab=12 IU/mL(0-34)

ANTITHYROGLOBULIN Ab=<20 IU/mL(0-40)

3 questions:

1.So I know that Ferritin is low, want to confirm that optimally the result

needs to about 90-150..right?

2.The lab does not show Hashimotos (because my results are not above range). But

I don't understand what <20 means? just less than 20? why wouldn't they put the

exact result.

3. How safe is it to assume I don't have Hashi's?

Thanks
