Your Iron Lab Checklist

Know what to test. Know what to ask. Know your next step.

Iron plays an important role in carrying oxygen throughout your body and supporting normal cellular functions, including those involved in hair growth.

If you’re experiencing hair loss, fatigue, or other symptoms that could be related to low iron, bloodwork can help you and your healthcare provider understand whether iron deficiency may be contributing.

Use this checklist to prepare for your next appointment.

1.Know Which Labs to Discuss

Ask your healthcare provider which tests are appropriate for your symptoms and health history.

Complete Blood Count (CBC)Checks hemoglobin and other blood cell measurements to help identify anemia. Iron deficiency can exist even when hemoglobin is normal.
FerritinMeasures a protein that reflects your body’s stored iron. Low ferritin can indicate depleted iron stores.
Serum IronMeasures the amount of iron circulating in your blood at the time of testing. It can fluctuate and shouldn’t be interpreted alone.
Total Iron-Binding Capacity (TIBC)Helps assess how much iron your blood can carry.
Transferrin Saturation (TSAT)Shows the percentage of available iron-binding sites occupied by iron. It is often calculated using serum iron and TIBC.

ℹ️ A CBC and ferritin are often useful starting points. Additional iron studies may help when results are unclear or when inflammation or other health conditions affect interpretation.

3.Questions to Ask Your Healthcare Provider

Use these questions to help guide your conversation and understand your next steps.

Do my results suggest iron deficiency, anemia, or another concern?
Is my ferritin appropriate in the context of my symptoms and health history?
Do I need additional tests to understand my iron status?
If my iron is low, what might be causing it?
Would dietary changes be sufficient, or is iron supplementation appropriate?
If supplementation is recommended, what dose and schedule should I follow?
When should I repeat my bloodwork to evaluate my response?

Iron and Hair Loss: A Quick Reminder

Iron deficiency is one possible contributor to hair loss, but it isn’t the only one. Correcting a deficiency supports overall health and may help when iron deficiency is contributing to shedding, but it doesn’t guarantee hair regrowth.

Avoid starting high-dose iron supplements based on symptoms alone. Too much iron can be harmful, and treatment should be guided by your results and individual needs.

Participate in your own healing.

Understanding your results is a meaningful first step toward making informed decisions about your health.
