Normal high ferritin refers to the upper limit of the normal range for ferritin levels in the blood, which varies depending on age and sex. Ferritin is a protein that stores iron, and its levels in the blood can indicate the amount of iron stored in the body.
Here's a breakdown of normal high ferritin levels based on the reference:
- Adults assigned male at birth: Up to 336 nanograms per milliliter (ng/mL)
- Adults assigned female at birth: Up to 307 nanograms per milliliter (ng/mL)
- Newborns: Up to 200 nanograms per milliliter (ng/mL)
It is important to note that these values serve as general guidelines. Healthcare professionals use these ranges combined with patient history and other tests to get the whole picture.
