Polycythemia often is used to describe an increase in the number of RBC's with no reference to the influctuations in leukocytesand platlets. However, this condition is more accurately termed erythrocytosis.
Polycythemia
is performed to treat polycythemia vera, a condition that causes an elevated red blood cell volume (hematocrit ). Phlebotomy is also prescribed for patients with disorders that increase the amount of iron in their blood.
Hematocrit is a measure of the proportion of blood volume occupied by red blood cells (RBCs). Therefore, it's represented as a percentage. The normal hematocrit for men is 46% with minor fluctuations between individuals labs.
Iron deficiency anemia. The normal hematocrit (ratio of packed red blood cells to total blood volume) rules out anemia due to loss of blood cells through hemorrhage or sickling. Below-normal hemoglabin indicates an iron deficiency in this case. No available iron = no hemoglobin produced.
Anemia will reduce the Hematocrit levels. Normal Hematocrit levels are 37-47 in females and 42-54 in males. In anemia, the levels are below normal. In polycythemia, they are above normal.
Hematocrit is one measurement among those that comprise the complete blood count (CBC) test, which measures many blood components. Hematocrit is the percent of total blood volume that is taken up by red blood cells. Normal hematocrit values are 46% RBCs in males and 38% in females.
No, their hematocrit will decrease. Though they may gain RBC, their plasma volume will have a greater increase in volume, thus decreasing the hematocrit concentration.

Hematocrit ^_______^
no. it is merely the ratio of blood volume test.
The hematocrit is also called the erythrocyte volume fraction, which is the percentage by volume of red blood cells in the blood. Erythrocyte is another name for the red blood cell in humans, so the higher the count, the larger the hematocrit.
Hematocrit measures the volume of the blood. It measures out in percentages of the whole blood that is made up of red blood cells.
