We usually look at the H&H of a blood count but there are other values to check.
The normal ranges for hemoglobin depend on the age and, beginning in adolescence, the sex 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.
The normal ranges for hematocrit are dependant on age and, after adolescence, sex. The normal ranges are:
- Newborns: 55-68%
- One (1) week of age: 47-65%
- One (1) month of age: 37-49%
- Three (3) months of age: 30-36%
- One (1) year of age: 29-41%
- Ten (10) years of age: 36-40%
- Adult males: 42-54%
- Adult women: 38-46%
These values may vary slightly between laboratories.
