What is the estimated normal range for hemoglobin (Hgb) in females?

10-14 g/dL
12-16 g/dL
14-18 g/dL
16-20 g/dL

The correct answer is: 12-16 g/dL

The estimated normal range for hemoglobin in females falls between 12 to 16 grams per deciliter (g/dL). This range is considered standard and reflects the physiological differences in hemoglobin levels between sexes due to factors such as body composition and hormone levels. Hemoglobin is a critical component of red blood cells, responsible for oxygen transport throughout the body. Maintaining levels within this normal range is essential for ensuring adequate oxygen delivery to tissues. Variations in this range can occur due to various factors such as altitude, pregnancy, and certain health conditions, but the established range of 12 to 16 g/dL remains the standard for average healthy adult females. Understanding these normal ranges is crucial for monitoring and diagnosing potential hematological issues in clinical practice.
