If you need to know which are the hemoglobin reference ranges or you require more information about the role of hemoglobin in the blood you can visit: Normal hemoglobin level in the blood
Hemoglobin is the protein present in the RBC (Red Blood Cells) that carries oxygen to the tissues of the body. It is usually measured in g/dl. A high hemoglobin level may be due to:
Secondary causes for hemoglobinemia includes hypoxia, inappropriate erythropoietin increase, associated with androgens or associated with chronic chemical exposure (nitrites, sulfonamides, cobalt, etc.)
Hemoglobin values are usually given in g/dl but sometimes you can see these values in mmol/l following the International System of Units (SI). In case your values are in mmol/l you can convert them using this tool:
Hemoglobinemia or a high hemoglobin level in the blood means:
The hemoglobin level in the blood is a bit high, above the normal range.
It is not a matter to be worried because it may be only due to high altitude, tobacco, obesity or stress.
Moderate hemoglobinuria is a marked polyglobulia that it is usually followed by a high hematocrit percentage (above 50% in women and 55% in men).
It may due to a disease known as polycythemia vera.
Severe hemoglobinuria leads to clogging of the capillaries as a result of hemoconcentration and the risk to suffer a cardiovascular disorder increases (heart attack, stroke or angina pectoris). It is necessary to look for immediate medical attention.
Severe hemoglobinuria may be due to a severe polycythemia vera or a dehydration consequence of a severe burn for example.
There are some health circumstances or drugs than can raise your hemoglobin level in the blood:

IMPORTANT: These levels are expressed in gr/dl. They are an example of a healthy woman of about 45 years old with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
