Polycythemia: A hemoglobin of 18.3 is just below the acceptable normal range of 18.5 in a male (some sources consider 18 to be cutoff). Any condition that causes an increase in red blood cell production by the bone marrow will cause an elevated hematocrit. A serious form of this is called poylcythemia vera, other conditions include living in high altitudes, tumors, heart&lung problems, etc.
