SERUM IRON (Screenshot end of video - still haven’t figured out my captions)
This is your circulating iron, free floating. Remember ferritin is your storage, so when iron increases your body pulls that in to store it.
Ideally this number stays on the upper range of your reference range for optimal health.
When serum iron levels drop, we start to suspect iron deficiency anemia. We need to evaluate your ferritin and your hemoglobin in this case. If all of those are LOW - likely anemia at play and we need to restore that iron.
When ferritin is low but iron is normal, we then need to investigate the WHY - why are you not storing that iron? Stay tuned as we investigate! Sometimes supplementing is the answer but sometimes absorption issues are at play.
