Iron tests measure different substances in the blood to check iron levels in your body. Iron is

a mineral that's essential for making red blood cells. Red blood cells carry oxygen from your

lungs to the rest of your body. Iron is also important for healthy muscles, bone marrow, and

organ function. Iron levels that are too low or too high can cause serious health

problems.Normal value range is: Iron: 60 to 170 micrograms per deciliter (mcg/dL), or

10.74 to 30.43 micromoles per liter (micromol/L) Total iron binding capacity ( TIBC ): 240

to 450 mcg/dL, or 42.96 to 80.55 micromol/L
