¿Cuál es el Nivel Normal de Ferritin?
Rangos normales: Ferritin (women) 16–232 ng/mL (many clinicians aim for >50); Ferritin (men) 38–380 ng/mL. Valores fuera de estos rangos pueden indicar una condición que requiere evaluación adicional.
Tabla de Rangos de Referencia
| Marcador | Bajo | Normal | Alto |
|---|---|---|---|
| Ferritin (women) | Below 16 ng/mL — depleted iron stores | 16–232 ng/mL (many clinicians aim for >50) | Above 232 ng/mL — inflammation or iron overload |
| Ferritin (men) | Below 38 ng/mL — low iron stores | 38–380 ng/mL | Above 380 ng/mL — inflammation or iron overload |
Qué Afecta los Resultados
Inflammation and infection (ferritin rises as part of the immune response), liver disease, alcohol use, recent blood donation, menstruation, and vigorous exercise can all affect ferritin levels.
Cuándo Repetir la Prueba
If supplementing for iron deficiency, retest in 8-12 weeks. Once optimal (>50 ng/mL), every 6-12 months for women and annually for men.
