Judged against the usual range for this sex and age. The lab’s own range wasn’t on the report. The open ring is the result before this one.

Down 52% since Jun 7, 2025

That's more than the usual test-to-test variation for Ferritin (a rise of 61% or a fall of 38%), so it's likely a real change.

Assumes the same lab and similar conditions, like fasting and time of day.

Over time

Ferritin has been lower than the time before at each of the last 4 tests.

Highest 42 ng/mL (Oct 2023), lowest 10 ng/mL (Sep 2026).

What a low result can mean

A low ferritin means your iron reserve is running low. It is common, especially in people who have periods, and it can happen before you become anemic. Because inflammation pushes ferritin up, a low value is a dependable sign of low iron, but a normal value can sometimes hide it.

Common causes

Heavy or long periods
Pregnancy, when your body needs more iron
Not enough iron in the diet
Poor iron absorption, for example with celiac disease or after some stomach or bowel surgery
Slow bleeding in the stomach or bowel
Frequent blood donation

What can help

Talk with your clinician about the cause, since finding where iron is being lost matters as much as replacing it
Ask whether iron treatment is right for you and how your level should be followed
Eat iron-rich foods such as meat, fish, beans, lentils and iron-fortified cereals
If there is no clear reason for low iron, ask whether a check for a source of bleeding makes sense

One result outside the range often has a simple explanation. Your clinician can put it in context with your health and other results.

Questions you could ask your clinician

What might be causing my iron stores to run low?
Should we recheck my blood count and ferritin after a few months?
Is there anything in my history, such as heavy periods or my diet, that matters here?
Is my lab's range the right comparison for my age and sex?
Does my ferritin change how you read my other iron results?
