ANATOMY

Detailed explanation-1: -A higher than normal hematocrit can indicate: Dehydration. A disorder, such as polycythemia vera, that causes your body to produce too many red blood cells. Lung or heart disease.

Detailed explanation-2: -Dehydration, the most common cause of a high hematocrit.

Detailed explanation-3: -As the dis-tribution shifts to the left or toward lower values with increasing age as it does for men, the mean hematocrit decreases. As the distribution shifts to the right or toward higher values with age, as it does for women until ages 55-64 years, the mean increases.

Detailed explanation-4: -When a high reticulocyte or WBC count is present, hematocrit determinations using hematology analyzers can result in the calculation of falsely elevated values, because the higher cell volumes of these cells will interfere with the red blood cell count and the calculation of the hematocrit [7].
