Red Blood Cell Count (RBC)

Red Blood Cell Count (RBC)?

RBC measures the number of red blood cells in the blood. Red blood cells transport oxygen from the lungs to the rest of the body, and transport carbon dioxide back to the lungs. If the EPK is low (anaemia), the body is unable to get the oxygen it needs. If the level is too high (a condition known as polycythaemia), there is a risk of the red blood cells clumping together and blocking the tiny blood vessels (capillaries). This also makes it difficult for the red blood cells to transport oxygen.

Why do we need to analyse RBC?

RBC is an important part of any health check. Deviations from normal levels may indicate anaemia.

Elevated RBC levels

High levels are seen in cases of polycythaemia (polycythaemia vera, oxygen starvation, dehydration).

Low RBC levels

Low levels are seen in cases of anaemia.
