We plan out all aspects of your trip. Figure 1 shows normal and abnormal hemoglobins. This examination is known medically as hemoglobin electrophoresis or hemoglobin electrophoresis, and it is a blood test that aims to measure and identify the different types of protein present in red blood cells, known as hemoglobin, and this protein is responsible for transporting oxygen to tissues and organs. Values above the norm of hemoglobin A2 (over 3,5% of the total) may indicate the presence of beta thalassemia or Mediterranean anemia. Normal adult: mainly HbA, small amounts HbA 2 (1.5-3.5%), HbF. Remember to take them regularly as levels can go back down once you stop taking them. Mutations in the hemoglobin can cause the body to produce faulty or abnormal hemoglobin. Experienced specialists perform non-invasive and minimally invasive surgeries to provide the best treatment for international patients. The hemoglobin electrophoresis with beta thalassemia trait usually has reduced or absent HbA, elevated levels of HbA2, and increased HbF.2 However, a normal concentration of HbA2 does not rule out beta thalassemia trait, especially if there was coexistent iron deficiency, which can lower HbA2 levels into the normal range. In adults, these are normal percentages of different hemoglobin molecules: HbA: 95% to 98% (0.95 to 0.98) HbA2: 2% to 3% (0.02 to 0.03) HbE: Absent HbF: 0.8% to 2% (0.008 to 0.02) HbS: Absent HbC: Absent In infants and children, these are normal percentage of HbF molecules: HbF (newborn): 50% to 80% (0.5 to 0.8) HbF (6 months): 8% 14th ed.
