If you have an increased ferritin level on your lab test it could indicate that your iron absorption is beyond the healthy limit. Depending on what is causing the high ferritin levels in the blood, the severity of the condition can vary.
Nonetheless, an elevated ferritin level can be alarming especially if it’s far above the upper limit of the normal range, which is around 200 ng/mL to 380 ng/mL, depending on age, sex, and the standards of the lab performing the test. A value that exceeds 1000 ng/mL is concerning as it could suggest chronic diseases that need immediate medical treatment.
Find out about the dangers of high serum ferritin levels, its treatment, and how you can help reduce it.

Ferritin Blood Test Overview
A ferritin blood test measures the level of ferritin – a protein that stores iron in all cells – which provides information about how much iron you have in your body.
Doctors usually will order this test to help diagnose iron deficiency anemia or an iron overload, as well as to aid in the detection of illnesses like liver disease and some cancers.
However, a ferritin lab test alone cannot accurately lead to a diagnosis. While it provides vital data about blood protein, it does not uncover its cause. Hence, you’ll have to take other tests in conjunction with the ferritin test, such as the transferrin blood test and iron-binding capacity (TIBC) blood test panel, which also make up the comprehensive iron profile blood test.
Did You Know? Iron overload can be indicated not just by high ferritin but also by increased TIBC. Find out more about what a high TIBC level means, its causes, and its treatment.
Ferritin Blood Test Meaning
Normal ferritin levels differ in terms of age and sex. For example, for men at 19 to 59, healthy ferritin level ranges from 38-380 ng/mL. On the other hand, the normal levels for women aged 41 to 60 range from 16-232 ng/mL.
However, these values can vary depending on the laboratory where you’re testing. Nonetheless, exceeding the upper limit indicates high ferritin levels, which can be associated with several health conditions. On the other hand, iron-deficiency anemia can be shown by low ferritin levels beyond the lower limit of the normal range.
What Ferritin Level Is Dangerously High?
Ferritin above 1,000 ng/mL can suggest alarming diseases, such as cancers, liver cirrhosis, and certain infections.
Generally, test values over the normal range indicate iron overload. Additionally, ferritin in serum at 400 ng/mL can imply inflammation, potentially linked to the abovementioned illnesses.
Ferritin Normal Range by Age and Sex
| Group | Normal Ferritin Range | Concerning Level |
|—|—|—|
| Men (19–59) | 38–380 ng/mL | Above 380 ng/mL |
| Men (60+) | 20–500 ng/mL | Above 500 ng/mL |
| Women (19–40) | 11–307 ng/mL | Above 307 ng/mL |
| Women (41–60) | 16–232 ng/mL | Above 232 ng/mL |
| All adults | Above 1,000 ng/mL | Critical — immediate evaluation |
| All adults | Below 30 ng/mL | Functional deficiency even if “normal” |
Low Ferritin — The Most Overlooked Blood Test Result
Most people searching for ferritin information actually have LOW ferritin — not high. Low ferritin is the earliest detectable sign of iron deficiency, appearing weeks to months before anemia develops on a CBC.
What low ferritin levels mean:
Below 30 ng/mL — Functional iron deficiency. Even if your result falls within the lab’s “normal” range, ferritin below 30 ng/mL frequently causes fatigue, hair loss, brain fog, restless legs, and reduced exercise tolerance — especially in women. Many integrative medicine providers use 50–70 ng/mL as the optimal threshold for symptom relief rather than the lab’s lower normal cutoff.
Below 12 ng/mL — Iron deficiency confirmed. At this level iron stores are severely depleted. Hemoglobin production is compromised and anemia is typically present or imminent.
Who is most at risk for low ferritin:
Women with heavy menstrual periods are the highest-risk group — monthly blood loss depletes iron stores faster than diet can replenish them. Pregnant women have dramatically increased iron demands. Endurance athletes lose iron through sweat and foot-strike hemolysis. Vegans and vegetarians absorb only non-heme iron which has lower bioavailability. Anyone with Crohn’s disease,
celiac disease, or H. pylori infection may have impaired iron absorption regardless of dietary intake.
The critical distinction:
You can have low ferritin with a completely normal CBC. This means your hemoglobin looks fine but your iron stores are already depleted. A ferritin test catches iron deficiency 6–12 weeks earlier than a CBC alone — which is why testing ferritin specifically is essential if you have fatigue or hair loss even with normal blood work.

Causes of High Ferritin Levels
Aside from dietary iron surplus, elevated ferritin levels can be associated with the following health conditions.
Hemochromatosis: This is a genetic condition wherein the body has no limit in terms of iron absorption. Hemochromatosis is hereditary and can be traced back to a defective gene. Left untreated, it leads to iron buildup that soon becomes toxic for the tissues, leading to more severe health afflictions.
Inflammatory disorders: Inflammation can drive an increase in ferritin levels. Hence, it can be linked to conditions in which inflammation chronically develops. These include rheumatoid arthritis, Still’s disease, fatty liver disease, acute infections, and chronic diseases like diabetes and certain cancers.
Hyperthyroidism: People diagnosed with an overactive thyroid like that in Grave’s disease often have elevated iron due to the increased production of ferritin. That said, improving your thyroid function can aid in the prevention of such a condition.
Heart Problems: Increased ferritin levels show in patients with cardiovascular diseases, such as atherosclerosis. After all, it is a risk factor for heart conditions and their mortality rate. One way to protect yourself from the said risk is by taking heart health blood tests, even as young as in your 20s.
Sideroblastic anemia: Also known as SA, sideroblastic anemia is rare but significantly affects red blood cell (RBC) function. It is characterized by the production of abnormal red blood cells containing hemoglobins that do not integrate iron. As a result, iron accumulates in the blood, and the RBCs fail to deliver oxygen to the cells, leading to various health problems.
Did You Know? Anemia comes in different types and degrees of impact on your health. Find out more about how this condition brings dangerous complications and everything you need to know about anemia.
While these disorders are closely linked to high serum ferritin, the condition alone does not strengthen the diagnosis. You will have to take other tests depending on factors like symptoms, your health record, and other risk factors.
How To Lower Your Ferritin Levels?
A high ferritin level will not go down on its own. Plus, you have to ensure that it normalizes before other debilities develop. Here are three ways to lower ferritin your doctor will likely prescribe or recommend.
Phlebotomy (Iron-rich Blood Removal)
Phlebotomy or venesection is a process of removing blood from the body, which in turn, reduces ferritin. The first stage of the treatment, also known as induction, requires a pint of blood extraction once or twice a week until serum iron levels are normal. After which, the frequency is reduced to two to four times a year for maintenance.
Having your blood drawn can be daunting, especially if you fear needles and blood tests in general. Learn how you can prepare for the procedure when you read out tips for getting blood drawn during a lab test.
Chelation Therapy
Another form of increased ferritin treatment includes chelation therapy or taking certain medications that bind and flush iron out and dietary adjustments. This alternative is only recommended with chelation therapy if you cannot undergo regular blood removal due to clinical reasons.
Lifestyle Changes
Keep in mind that the body does not produce its own iron. Instead, the mineral is absorbed from foods consumed along with other nutrients. Thus, you can aid in remedying the increased ferritin level by adjusting your diet and avoiding foods rich in iron on top of the treatments.
You can do this by removing iron-rich foods from your diet, particularly sources of heme iron (found in animal flesh).
- Poultry
- Red meat
- Fish and shellfish
- Iron-fortified food
Non-heme iron, found in plants, is absorbed less quickly, which is why it’s generally acceptable to consume iron-rich fruits and vegetables like leafy greens. Still, it has to be regulated. Nonetheless, if you are unsure about your iron intake after testing high for ferritin, consult with your doctor.
Additionally, as you reduce your consumption of iron-rich foods, increase your intake of foods high in antioxidants. Doing so can protect your tissues from the damage caused by hemochromatosis. Include the following in your grocery list:
- Oranges
- Broccoli
- Spinach
- Asparagus
- Carrots
- Kale
- Pumpkin
- Potatoes
Aside from your diet, you will most likely have to give up some habits that aggravate iron overload or its potential complications, particularly smoking and alcohol drinking. Substances absorbed in both activities adversely impact iron levels and cause further damage to the liver and lungs.
If you’re planning to let go of smoking for good, there are several things you have to keep in mind to make sure you succeed with your health goal. Check out the mistakes you should avoid when quitting smoking.
Test Your Ferritin and Iron Levels — No Doctor Visit Needed
A ferritin blood test is the single most important first step for evaluating iron status — catching deficiency before it progresses to anemia, and catching overload before it causes organ damage.
For iron deficiency screening —start with the Ferritin Blood Test. If low, add the Iron and TIBC Panel to confirm and quantify the deficiency.
For iron overload screening —the Comprehensive Iron Profile bundles ferritin, serum iron, TIBC, and transferrin saturation in a single draw — giving you the complete picture your doctor uses to evaluate hemochromatosis.
For athletes and women with fatigue —ferritin below 30 ng/mL is frequently the hidden cause even when standard blood work looks normal. Test it specifically.

Frequently Asked Questions: Ferritin Blood Test
How do you treat high levels of ferritin?
What is a dangerous ferritin level?
Ferritin above 1,000 ng/mL is considered concerning and may indicate serious conditions including hemochromatosis, liver cirrhosis, certain cancers, or severe chronic inflammation. Ferritin above 500 ng/mL warrants medical evaluation. For context, normal ferritin for men is 38–380 ng/mL and for women 11–307 ng/mL depending on age — though reference ranges vary by laboratory.
What does low ferritin mean?
Low ferritin means your iron stores are depleted. Ferritin below 30 ng/mL frequently causes fatigue, hair loss, brain fog, and restless legs even if other blood work looks normal. Below 12 ng/mL confirms iron deficiency. Low ferritin is the earliest detectable sign of iron deficiency — appearing weeks to months before anemia shows up on a CBC.
What causes high ferritin?
The most common causes of high ferritin are hemochromatosis (genetic iron overload), liver disease, chronic inflammation, type 2 diabetes, metabolic syndrome, hyperthyroidism, and certain cancers including leukemia and lymphoma. Ferritin is also an acute phase reactant — it rises with any significant inflammation or infection, which is why a single elevated result always needs context.
Do I need to fast before a ferritin blood test?
No fasting is required for a standalone ferritin blood test. You can eat and drink normally before your blood draw. If you are combining ferritin with an iron panel or lipid panel in the same visit, those tests may require fasting — check the preparation instructions for each.
What other tests should I order alongside ferritin?
A ferritin test tells you your iron storage level but not the full picture. Adding serum iron and TIBC (Total Iron Binding Capacity) gives you iron transport capacity and saturation percentage. Together ferritin, serum iron, and TIBC allow your provider to distinguish iron deficiency anemia from anemia of chronic disease — two conditions that look similar on a CBC but require completely different treatment.
Can I order a ferritin test without a doctor?
Yes. Personalabs provides the physician-signed lab order as part of your purchase. Order online, visit any Labcorp patient service center near you, and get results in your secure account within 24–48 hours. No referral, no insurance, no doctor visit required.
The Bottom Line
Ferritin blood test reveals more than just abnormalities in your serum iron. It also provides additional information for conditions involving your kidneys, heart, lungs, and other vital organs, which aids your doctor in prescribing the proper treatment.
If your blood test reveals a high ferritin level, you will most likely take other tests to diagnose the exact cause of the condition, which could include the TIBC blood test panel.
