Serum ferritin levels in apparently healthy subjects

ABSTRACT

Serum ferritin levels were estimated in 78 normal subjects [46 males and 37 females] using radioimmunoassay techniques. The mean serum ferritin level in normal men was 83 ng/ml [range 7.4 - 190.0 ng/ml], compared with 43 ng/ml [range 5.1 - 104 ng/ml] in normal women. The difference in the mean ferritin level between the two sexes was significant. A concentration below 10 ng/ml was associated with a low transferrin saturation [< 15%] in both males and females
