In adults, these hemoglobin molecules make up the following percentages of total hemoglobin:

• Hb A: 95% to 98%
• Hb A2: 2% to 3%
• Hb F: 0.8% to 2%
• Hb S: 0%
• Hb C: 0%

In infants and children, these hemoglobin molecules make up the following percentages of total hemoglobin:

• Hb F (newborn): 50% to 80%
• Hb F (6 months): 8%
• Hb F (over 6 months): 1% to 2%

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

The presence of significant levels of abnormal hemoglobins may indicate:
