Hemoglobin 167g/L is normal for newborns and is elevated for adults. 1. The normal value of hemoglobin in newborns is 170 to 200 g/L, so hemoglobin 167 g/L is normal for newborns. The normal value of hemoglobin in adult men is 120-160g/L and in adult women is 110-150g/L, so hemoglobin 167g/L is elevated in adults. 2. The reason for the increase may be in the environment of low oxygen concentration for a long time, such as living in the plateau area, which can make the hemoglobin count appear physiological increase; the decrease of body fluids, such as after a large amount of water loss, which causes the blood to concentrate, the hemoglobin count will be higher than the normal value; there are also some diseases, such as chronic obstructive pulmonary disease, erythrocytosis, ovarian cancer, hepatocellular carcinoma and so on, which will also appear the hemoglobin increase. There may be other reasons for hemoglobin 167g/L. If you are not feeling well, it is recommended that you go to the hospital in time to find out the cause of the disease and then target treatment.
