Hemoglobin
The hemoglobin concentration is an important criterion for the diagnosis and differentiation of anemias, erythrocytoses and polycythemias.
Reference Ranges
| Women | 12.3 - 15.3 g/dL | 7.62 - 9.48 mmol/L |
| Men | 14.0 - 17.5 g/dL | 8.67 - 10.8 mmol/L |
| Newborn | 15.2 - 23.5 g/dL | 9.42 - 14.6 mmol/L |
| Baby | 10.1 - 12.9 g/dL | 6.26 - 7.99 mmol/L |
| Infant | 10.8 - 12.8 g/dL | 6.69 - 7.93 mmol/L |
| Children | 11.1 - 14.3 g/dL | 6.88 - 8.86 mmol/L |
Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
