The goal is to treat the underlying cause so they eventually don’t need supplementation but that’s not possible for everyone

Yes treatment guidelines to follow. Ferritin target is 30 in most adults, 50 if symptoms or risk factors, 100 if inflammation

Ugh that’s rough. IV might be a good option and these are for optimal absorption but there’s still some absorption if you do it differently

I’m apparently now on TikTok posting about iron 🤦‍♀️

The nicest thing about it is being able to chat with the patient without taking notes or staring at the computer

The guidelines are meant to be used internationally and my good friend Michelle Sholzberg already changed the majority of labs in Ontario!

I’m so happy that the @ash.hematology.org guidelines are getting a lot of attention but all these influencers who don’t actually understand iron deficiency posting about it is making me CRAZY.

It’s been a long time coming but hopefully will help many people. It’s hard with inflammation so tsat can be helpful (needs to be fasting) and if <20% is diagnostic

Shematologist, MD @shematologist.medsky.social · 18/09/2026

Yes I would consider autoimmune disease as inflammatory

Shematologist, MD @shematologist.medsky.social · 17/09/2026

Yep, less data and some data on other parameters having an inflection point around 20 in kids

Shematologist, MD @shematologist.medsky.social · 17/09/2026

Depends on if you have ongoing losses

Shematologist, MD @shematologist.medsky.social · 17/09/2026

If menstruating I would use the 30 cutoff. There’s very little data in middle child ages as iron deficiency very rare outside of those who menstruate

So common in donors! It’s a real problem.

This makes me so incredibly happy for you and your baby 💜

THANK you my ferritin was in the toilet a few years ago - I think it was 14 when I realized I needed to test for it. never showed up in my hemoglobin numbers, but iron deficiency made me feel like I was dying very very slowly I fixed it with a hysterectomy tl;dr low ferritin w/o anemia is awful

Worth spreading far and wide, and adding to one's personal file of "health basics for women" to keep an eye on.

No, if low and symptomatic then need treatment regardless of hemoglobin

Our lab’s lower limit of normal for ferritin for adult women is um much much much lower than this

1181

Shematologist, MD @shematologist.medsky.social · 17/09/2026

These numbers are meant for otherwise healthy adults. In those with inflammation cutoffs should be even higher

Thank you for all of that important work 💜

On a personal note, my lowest ferritin was 9 (after a few, in retrospect, ill-advised RBC donations) and has only made it up to 26 after several months of PO supplementation. Very relieved insurance can’t give me/my PCP pushback on infusions with these new guidelines. AFAB folks take note!!

Landmark paper, with new iron deficiency diagnosis guidelines. Studies found that 27% of women have iron deficiency. Associated conditions (celiac, inflammatory conditions, kidney disease, heart failure) may be investigated and caught much sooner as a result. #anemia @shematologist.medsky.social
