SUMMARYAND MEASUREMENT RANGE
Hemoglobin is the main component of red blood cells whose main function is to transport oxygen. The determination of hemoglobin concentration in whole blood is useful in the clinical diagnosis of diseases such as anemia and polycythemia.
| Test Type | Measurement Range |
| Hemoglobin(Hb) | 4.5-25.6 g/dL (45-256g/L, 2.8-15.9mmol/L) |
PRINCIPLE AND REFERENCE VALUES
Erythrocytes in the specimen are lysed to release hemoglobin. The hemoglobin is converted to methemoglobin. The intensity of the color produced from this reaction is proportional to the hemoglobin concentration. Reference values are listed in the chart below:
| Men | 13.0-17.0 g/dL(130-170 g/L, 8.1-10.5 mmol/L) |
| Women | 12.0-15.0 g/dL(120-150 g/L, 7.4-9.3 mmol/L) |
| Children | 11.0-14.0 g/dL(110-140 g/L, 6.8-8.7 mmol/L) |
Reference ranges may vary between laboratories. Every laboratory should establish its own reference range as needed.
