Hello Restu, thank you for asking.
Hemoglobin is a component of red blood cells that functions to transport oxygen to tissues. Hemoglobin consists of heme and globin molecules. Globin molecules consist of several subtypes, namely alpha, beta, gamma, and delta chain globins. Each red blood cell has 4 globin chains. In adults, the most hemoglobin is Hb type A, as much as 95-98 of the total amount of hemoglobin. Hb A consists of two alpha globin chains and two beta globin chains.
In addition, in adults there are also Hb type A2 and Hb type F. Both of these Hb are commonly found in fetuses and after birth, will be gradually replaced by Hb A. Therefore, in adults, normally there are only about 2-3% Hb A2 and 0.8-2% Hb F.
Increased levels of Hb A2 and Hb F in adults, may indicate the presence of blood diseases. For example thalassemia and hemoglobinopathy. However, we cannot determine whether your Hb value is normal or not, because you did not specify the unit and range of normal values used in the lab. We don't know whether that number has a unit of percent or mg / dL. Therefore, you should bring these results back to the treating doctor. The doctor will match the lab results with the results of your physical examination. Normal or not, the doctor has the right to determine.
Thus my answer, hopefully enough help. Regards.
