The required amount of ferritin to maintain healthy levels varies depending on sex. Normal ferritin levels range between 12 and 150 nanograms per milliliter (ng/mL) for females and from 15 to 200 ng/mL for males.
Here's a breakdown in table format:
| Sex | Normal Ferritin Range (ng/mL) |
|---|---|
| Females | 12 - 150 |
| Males | 15 - 200 |
Therefore, the required ferritin level should fall within these sex-specific ranges to ensure proper iron storage and overall health.
