What is the normal range for Hemoglobin (Hb) according to the provided markers?

The normal range for hemoglobin (Hb) levels is significant for assessing an individual's oxygen-carrying capacity and overall health. In healthy adults, the typical range is approximately 12 to 15 g/dL for women and 13.5 to 17.5 g/dL for men.

The range of 15-17 g/dL generally covers the typical normal range for adult males, indicating a healthy level of hemoglobin. This range is crucial as it reflects adequate oxygen transport capabilities within the blood, which is essential for maintaining energy levels and organ function. When hemoglobin levels fall below these ranges, it can lead to conditions like anemia, compromising the body’s ability to deliver oxygen effectively.

In contrast, the other options suggest lower ranges (10-12 g/dL and 12-15 g/dL) or a much higher range (20-22 g/dL) that would not be applicable in typical clinical settings. Such levels outside the expected normal could indicate various health issues requiring further investigation or treatment.
