élevé d`hémoglobine dans un plasma et résultats de test des valeurs référents. What does high Hemoglobin in plasma test result referent values level mean?

Upper limit of normal Hemoglobin in plasma test result referent values is 0.62(μmol/L ) - 4(mg/dL).

The efficient sequestration of hemoglobin by the red blood cell membrane and the presence of multiple hemoglobin clearance mechanisms suggest a critical need to prevent the buildup of this molecule in the plasma.

High hemoglobin levels may be caused by exposure to high altitudes, smoking, dehydration, or tumors
