Is Ferritin 336 high, normal or dangerous? What does Ferritin level 336 mean?

📅 Medical Review Date: September 21, 2025

Your Ferritin level of 336 is a High Ferritin level.

A ferritin level of 336 ng/mL usually means the body has too much stored iron or there is inflammation. It suggests iron overload. High levels of ferritin can cause joint pain, fatigue, abdominal pain, weakness, heart palpitations, low libido, and bronze or gray skin color. This can be caused by hemochromatosis, chronic inflammation, liver disease, or iron poisoning. Further tests are often needed to identify the cause and guide appropriate treatment.

High Ferritin levels may indicate underlying health problems. The normal range is typically between 22 ng/mL and 322 ng/mL. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal Ferritin range for men is :22 - 322 ng/mL

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

Some examples of conditions that increase or decrease Ferritin levels include:

• Iron overload or iron poisoning
• Adult Still's disease
• Liver disease
• Iron deficiency anemia
• Hemachromatosis
