Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. A:The normal Hb A2 level in an adult is less than 3.5% and it is elevated (>4%) in b-thalassaemia trait. Rarely, mutations in or near these genes can also be responsible for the disease. The HbA2 level for HbE heterozygotes was 3.58% (SD 0.44%), which was significantly higher than normal (p < 0.001) but lower than that of beta-thalassaemia heterozygotes (p < 0.001) and the true HbE level was 24.28% (SD 3.38%). For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute. Hemoglobin electrophoresis is used as a screening test to identify variant and abnormal hemoglobins, including hemoglobin A1 (HbA1), hemoglobin A2 (HbA2), hemoglobin F (HbF; fetal hemoglobin), hemoglobin C (HbC), and hemoglobin S (HbS).

Hemoglobin A2 (HbA2) is a normal variant of hemoglobin A that consists of two alpha and two delta chains (α2δ2) and is found at low levels in normal human blood. Thalassemia Major and Intermedia Patients in East Java do not Show Fetal Hemoglobin Level Difference in Relation to XMNI Polymorphism. The normal ranges for hemoglobin depend on the age and, beginning in adolescence, the gender of the person.
