The hemoglobin level is expressed as the amount of hemoglobin in grams (gm) per deciliter (dL) of whole blood, a deciliter being 100 milliliters.

The normal ranges for hemoglobin depend on the age and, beginning in adolescence, the gender of the person. The normal ranges are:

  • Newborns: 17-22 gm/dL.
  • One (1) week of age: 15-20 gm/dL.
  • One (1) month of age: 11-15gm/dL.
  • Children: 11-13 gm/dL.
  • Adult males: 14-18 gm/dL.
  • Adult women: 12-16 gm/dL.
  • Men after middle age: 12.4-14.9 gm/dL.
  • Women after middle age: 11.7-13.8 gm/dL.

All of these values may vary slightly between laboratories. Some laboratories do not differentiate between adult and "after middle age" hemoglobin values.
