What identifies the percentage of red blood cells in a specific volume of blood?
Hematocrit (HCT, packed cell volume, PCV). This test measures the amount of space (volume) red blood cells take up in the blood. The value is given as a percentage of red blood cells in a volume of blood. For example, a hematocrit of 38 means that 38% of the blood’s volume is made of red blood cells.

The specific number for high white blood cell count varies from one lab testing facility to another, but a general rule of thumb is that a count of more than 10,500 leukocytes in a microliter of blood in adults is generally considered to be high, while 4,500-10,500 is considered within the normal range.
What causes a high RBC count?
A high RBC count may be a result of sleep apnea, pulmonary fibrosis, and other conditions that cause low oxygen levels in the blood. Performance-enhancing drugs like protein injections and anabolic steroids can also increase RBCs . Kidney disease and kidney cancers can lead to high RBC counts as well.
What causes a High RDW?
High RDW levels can also be caused due to the use of performance enhancing drugs like anabolic steroids or protein injections. Dehydration can also be another factor that contributes to high RDW. In such a case, the plasma gets decreased and as a result the count of red blood cells increases.
