Which lab result would be considered out of the normal range for an adult male?

The lab result indicating a hemoglobin level of 10.0 g/dL is considered out of the normal range for an adult male, as normal hemoglobin levels typically range from about 13.5 to 17.5 g/dL. A hemoglobin level of 10.0 g/dL is indicative of anemia, as it falls significantly below the standard reference range, suggesting that the individual may have a reduced capacity for oxygen transport in the blood.

In contrast, a hematocrit level of 40% is generally within the normal range for adult males, which typically falls between 40% and 52%. Similarly, a mean corpuscular volume (MCV) of 90 fL aligns with normal values, as MCV usually ranges from about 80 to 100 fL, indicating that the size of the red blood cells is appropriate. Lastly, a mean corpuscular hemoglobin concentration (MCHC) of 32 g/dL is also within normal limits; normal values range from approximately 31% to 36%. Thus, the hemoglobin level of 10.0 g/dL distinctly stands out as abnormal for an adult male.
