Decreased hematocrit and hemoglobin levels may result from
a. high altitude. c. leukemia.
b. cyanotic heart defects. d. severe dehydration.
C
Hematocrit determines the percentage of red cells to volume of whole blood. It reflects the body's iron supply. Hemoglobin is the iron component of the blood that transports oxygen. Moderate to severe anemia (a decrease in hematocrit and hemoglobin) may indicate decreased iron intake, leukemia, cirrhosis, hyperthyroidism, hemorrhage, hemodilution, or hemolytic reactions. Increased hematocrit and hemoglobin normally occur with people living in high altitudes because of the decrease in partial pressure of oxygen in those areas.
