What are normal hemoglobin values?

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