Ferritin

Item Catalog Number: LC004598

Ferritin is a protein produced in the liver for the storage of iron. Ferritin is a sensitive and specific test that helps your doctor diagnose iron deficiency anemia. In general, a healthy ferritin level is greater than 20 ng/mL.

Higher levels of ferritin, greater than 400 ng/mL, are consistent with iron overload which is called hemochromatosis.

Fasting is not required. Take all medications as prescribed. Do not take your supplements the day of the test.

Ferritin and Thyroid Function

By TRT Phoenix

Comments about Life Extension Blood Labs Ferritin Blood Test:

Ferritin is vital for thyroid function. Without sufficient ferritin a person taking thyroid medication may experience hyperthyroid symptoms because the hormone is not able to communicate/enter the cells. And my ferritin levels were on the low side even though I had been supplementing with 65mg iron daily for several weeks. My serum iron was high though, which means it can take a while to build ferritin levels in the body.

I take my iron at least 4 hours after I take my Liothyronine to make sure they both absorb properly. I make sure to space out my calcium about 4 hours as well. That's why I take calcium citrate, magnesium citrate and Vitamin D-3 at bedtime.
