Normal iron levels for men range from 70–175 micrograms per deciliter (mcg/dL), according to WebMD. These values often vary between laboratories, and for some people, their "normal" levels may be slightly higher or lower. If an iron related condition is suspected, a doctor may order a serum iron test to check the iron levels in a person's blood.
As noted by MedlinePlus, additional values obtained from the serum iron test include total iron-binding capacity and transferrin saturation. A normal TIBC range is 240 to 450 mcg/dL, while the normal range for transferrin saturation is between 20 and 50 percent. To perform this testing, a blood sample is required. Iron levels are higher in the mornings, so patients are often advised to undergo a blood draw early in the day.
