Final answer:
The hemoglobin concentration reference range for adults is approximately 12-16 g/dL for men and 11-15 g/dL for women.
Step-by-step explanation:
The hemoglobin concentration reference range for adults is approximately 12-16 grams per deciliter (g/dL) of blood for men and 11-15 g/dL for women.
Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. The concentration of hemoglobin can vary depending on factors such as age, sex, and overall health.
A deficiency in hemoglobin can indicate anemia, which can cause symptoms such as fatigue, pale skin, and shortness of breath.
