What is considered a normal hemoglobin value in an adult male?

10 g/dL
15 g/dL
20 g/dL
25 g/dL

The correct answer is: 15 g/dL

A normal hemoglobin value for adult males typically ranges from about 13.8 to 17.2 grams per deciliter (g/dL), with 15 g/dL being a commonly recognized value within this range. Hemoglobin is a crucial protein in red blood cells responsible for transporting oxygen throughout the body, and maintaining healthy levels is essential for overall well-being and physical performance. Values below the normal range may indicate conditions like anemia, while significantly higher values can point toward dehydration or other health issues. It is important to be aware of these normal ranges for accurate assessment of an individual’s health and to guide potential interventions if levels are found to be abnormal. Knowing the normal range helps healthcare professionals make informed decisions during diagnosis and treatment.
