Ferritin levels vary significantly with age and sex, reflecting different physiological needs and iron storage capacities. Here's a breakdown of typical ranges:
Ferritin Level Ranges by Age and Sex
| Age Group | Ferritin Level (ng/mL) |
|---|---|
| Newborns | 25 to 200 |
| 1 Month Old | 200 to 600 |
| Adult Males | 24 to 336 |
| Adult Females | 24 to 307 |
Important Considerations
- Individual Variation: These ranges are general guidelines. Individual health conditions, medications, and lifestyle factors can affect ferritin levels.
- Clinical Interpretation: Ferritin levels should always be interpreted in the context of other clinical findings and blood tests. A single abnormal result might not indicate a serious problem and further investigation is often needed.
- Low Ferritin: Low ferritin levels usually indicate iron deficiency, potentially due to poor intake, chronic blood loss, or malabsorption.
- High Ferritin: High ferritin levels can indicate inflammation, liver disease, certain cancers, and conditions like hemochromatosis (iron overload).
- Consult a Doctor: If you're concerned about your ferritin level, consult a healthcare professional for appropriate assessment and treatment.
Practical Examples
- A newborn with a ferritin level of 150 ng/mL is within the typical range.
- A 1-month-old infant with a ferritin level of 400 ng/mL is within the normal expected range.
- An adult male with a ferritin level of 200 ng/mL is within the normal range for adult males.
- An adult female with a ferritin level of 50 ng/mL could potentially be iron deficient and further evaluation is needed.
