Definition of Hemoglobin normal values

Hemoglobin normal values

Hemoglobin, the key oxygen-transporting pigment in the blood, serves as the primary protein component. In standard lab tests for hemoglobin (Hb), its concentration is typically determined by measuring the total hemoglobin. The results are given in grams (gm) per deciliter (dl) of whole blood, with a deciliter equaling 100 milliliters. Normal hemoglobin levels vary based on age and, starting from adolescence, gender. The typical ranges are as follows:- Newborns: 17-22 gm/dl- One week old: 15-20 gm/dl- One month old: 11-15 gm/dl- Children: 11-13 gm/dl- Adult males: 14-18 gm/dl- Adult females: 12-16 gm/dl- Men beyond middle age: 12.4-14.9 gm/dl- Women beyond middle age: 11.7-13.8 gm/dlIt's important to note that these values can slightly differ between laboratories. Some labs may not distinguish between hemoglobin levels for adults and those "after middle age."
