Ferritin Testing Labs in Washington

Ferritin testing measures the amount of ferritin in your blood. Ferritin is a protein that stores iron, so this test helps assess your body's iron reserves. It is often ordered when iron deficiency or iron overload is suspected.

What it measures

Ferritin — The main marker; reflects how much iron is stored in your body.
Iron — Sometimes measured alongside ferritin to see current iron levels in the blood.
Total Iron-Binding Capacity (TIBC) — Shows how well your blood can transport iron.
Transferrin Saturation — Calculated from iron and TIBC; indicates how much transferrin is carrying iron.

Who it is for

A healthcare provider may order ferritin testing if you have symptoms of low iron, such as fatigue or pale skin, or if you have a condition that affects iron absorption or storage. It can also be used to monitor certain treatments.

Preparation

No fasting is usually required for ferritin testing. However, if other tests are done at the same time, your provider may give specific instructions.

Results and what they mean

Results are reported as a number with a reference range, typically in nanograms per milliliter (ng/mL). Your clinician interprets the result along with your symptoms, medical history, and other tests. This information is general and not a substitute for medical advice.
