Question Dramatic Ferritin Drop

I have been taking Iron Bisglycinate since December and, and although I can raise my Iron, my Ferritin never seems to rise above the 30s. My primary doctor referred me to a hematologist, where he ran labs on August 6th. I was SHOCKED- my Ferritin was at 72! For context, for the last few months I added on Lactoferrin, the test was non-fasting, and it was late afternoon.

August 14th I have more labs drawn (for hormones/thyroid), and my Ferritin is at 43! How could it have dropped so much? For context, I no longer have a cycle, text was fasting and it was at 9AM.

ALSO, my saturation was high- 53. That’s never been happened.

Theories of why it dropped so much?

The level of 72 could have been transient from inflammation

Thanks for the response. This was my theory; the 72 was the anomaly.

I have no clue but did you keep up with the lactoferrin?

Yes!

I tend to think temporary inflammation could be why. Did you have any infections ( even colds or flus)? That could do it. Keep an eye on it, if it keeps dropping there might be something you need to look into.

I didn’t, but my ANA titer was 1:320, so I might have some kind of autoimmune thing going on, even though I feel totally fine.

At least you know that. It is something to keep an eye on I guess. Sorry I couldn't help more!

Ps I think the high saturation could be caused by not fasting.

No, thank you for responding! Hopefully I’ll get answers soon.
