What is the normal red blood cell (RBC) count range for males in x 10^12/L?

The normal red blood cell (RBC) count range for males is typically between 4.6 and 6.2 x 10^12/L. This range reflects the healthy level of red blood cells necessary for optimal oxygen transport and overall physiological function.

Maintaining an appropriate RBC count is crucial for delivering oxygen to tissues and removing carbon dioxide from the body. A count within this range indicates that the body has an adequate capacity to carry oxygen, which is essential for metabolic activities. Variations outside this range may suggest either a potential deficiency or an excess, leading to various clinical implications.

In comparison to the other provided options, this range is precise and aligns with established medical standards for normal RBC counts in adult males. The other ranges indicated may not accurately represent the typical physiological thresholds observed in clinical practice.
