Introducing Chris Masterjohn Lite

In this episode, I break down an iron panel and explain why it’s important to also measure serum ferritin and transferrin, and when you should use transferrin saturation instead of iron saturation as a marker of your short-term iron status.

  1. Hi Chris, I just listened to your podcast. My ferritin is 13ng but my iron panel looks normal (Iron – 116ug, TIBC – 369, Iron Sat. 31.4%). My CBC also looks good – MCV is 97, MCH is 31. I’m on an iron supplement to help raise my ferritin in addition to trying to increase iron in my diet as suggested by my GP but now I’m concerned this may be hurting me if my iron panel is ok. Where is this iron going?

  2. Chris,

    My iron saturation is 44% and ferritin is only 43. Do you recommend donating blood to get my iron sat in the 30s, or should I wait until ferritin is higher? (Or measure transferin saturation to be safe?)


    1. I’d measure transferrin saturation. I think donating blood should be fine as long as your CBC measures stay in line and you don’t develop any negative symptoms.
