Generally speaking, the normal value of hemoglobin for adult men is 120~160g/L, and for women is 110~150g/L. If the actual value exceeds this range, it means that there is an elevated hemoglobin concentration, which may be either physiological or pathological, with different clinical significance for different types.
1. Physiological elevation of hemoglobin: It is a temporary abnormality, which may be caused by low water intake or heavy sweating, and blood concentration after excessive water loss, at this time the hemoglobin concentration will be higher than normal. However, after these problems are relieved, the hemoglobin concentration will gradually return to normal.
2. Pathological hemoglobin elevation: If the concentration of hemoglobin is obviously higher than normal and can’t be relieved, then it is likely to be pathological hemoglobin elevation, which means that the patient may suffer from some myeloproliferative diseases, such as chronic granulocytic leukemia, true erythrocytosis, primary thrombocythemia, and some chronic cardiopulmonary diseases, etc. Therefore, if the hemoglobin concentration in the routine blood test is higher than normal, the patient may suffer from some myeloproliferative diseases.
Therefore, if the phenomenon of elevated hemoglobin is found in the routine blood test, then we should continue to carry out further examination under the guidance of the doctor, so as to clarify the cause of the disease as soon as possible, and then actively carry out causative treatment, so as to avoid deterioration of the condition and missing the best time for treatment.
