# Always Exhausted? Your Iron Stores — Not Just Your Blood Count — Could Be Why
"Your blood count is normal." It's one of the most confusing things to hear when you're still exhausted, still losing hair, still feeling like your body is running on empty. The explanation is often hiding in a test that doesn't get ordered as often as it should: ferritin.
## Ferritin Isn't the Same as Iron
A standard full blood count can look completely normal even when your body's iron reserves are running low. That's because ferritin reflects how much iron your body has stored, not just what's circulating in your blood at that moment. Think of it as the difference between checking your take-home pay and checking your savings account — a full blood count shows one snapshot, while ferritin shows what's actually in reserve.
This is why someone can be told their hemoglobin is "fine" while quietly running low on the iron stores their body needs to function well.
## Signs Your Iron Stores Might Be Low
Low ferritin can show up in ways that are easy to explain away as stress, poor sleep, or "just being busy." Common signs include:
- Persistent fatigue that doesn't improve with rest
- Pale skin
- Brittle nails or thinning hair
- Restless leg syndrome
- Unusual cravings for non-food items like ice (a lesser-known but real sign of iron deficiency)
- Heavy menstrual periods
- Known or suspected anemia
- A family history of hemochromatosis (iron overload)
Ferritin testing is useful in both directions — it can reveal iron deficiency or, less commonly, iron overload, both of which need different management.
## Who Should Consider Getting Tested
Women with heavy periods, anyone with ongoing unexplained fatigue, people with a plant-based diet, and those with a family history of iron-related conditions are all good candidates for a ferritin check. If you've had a full blood count come back "normal" but you still don't feel like yourself, ferritin is often the next logical step.
## What to Expect
The test itself is simple: a phlebotomist collects a small blood sample. Because iron levels naturally fluctuate throughout the day, a morning fasting sample gives the most accurate reading. At Mascot Healthcare, results come back the same day, with a doctor available to explain what the numbers mean and what to do next.
## The Bottom Line
A "normal" blood count doesn't always tell the whole story. If fatigue, hair thinning, or other symptoms have been lingering without explanation, checking your iron stores directly — rather than just your blood count — can finally connect the dots.

## Frequently Asked Questions
**What is a normal ferritin level?**
Reference ranges vary between labs, but ferritin is generally considered normal somewhere between roughly 20–250 ng/mL in men and 20–150 ng/mL in women. Always check the specific range printed on your own lab report, since cutoffs differ by testing method.
**What ferritin level is considered low?**
Many labs flag ferritin as low once it drops below roughly 15–30 ng/mL — a point at which iron stores are often depleted even while hemoglobin still looks "normal" on a standard blood count.
**Can low ferritin cause hair loss?**
Yes. Iron plays a role in hair follicle function, and low ferritin has been linked to hair thinning and shedding, even in people who aren't clinically anemic.
**Is a ferritin test the same as an iron test?**
No. A serum iron test measures how much iron is circulating in your blood right now, while ferritin measures how much iron your body has stored for later use. The two are often ordered together for a fuller picture, alongside a full blood count.
**Do I need to fast before a ferritin test?**
A morning fasting sample is generally preferred, since iron levels naturally fluctuate throughout the day and fasting gives a more accurate baseline reading.
**What causes low ferritin besides diet?**
Heavy menstrual periods, pregnancy, gastrointestinal blood loss, and certain digestive conditions that affect iron absorption can all lower ferritin, independent of how much iron-rich food you eat.
