The normal range for blood ferritin varies by gender and age. Generally, normal ferritin levels are:
- For adult males: 30 to 400 nanograms per milliliter (ng/mL)
- For adult females: 13 to 150 ng/mL
However, it's important to note that these ranges can vary slightly depending on the laboratory performing the test. If you have concerns about your ferritin levels, it's best to discuss them with your doctor.
