Infants tend to have higher average hemoglobin levels than adults. This is because they have higher oxygen levels in the womb and need more red blood cells to transport the oxygen.

| 11–18 years | 11.9–15.0 | 12.7–17.7 |

Do hemoglobin levels change with age?
Conclusions: Age is significantly associated with both hemoglobin levels and anemia, with a stronger effect in men compared with women, even after simultaneously adjusting for demographic characteristics and health status.
What is the normal Haemoglobin level of a child?
Normal ranges are as follows: Children: 11-13 gm/dL. Adult males: 14-18 gm/dL. Adult women: 12-16 gm/dL.
What is the normal hemoglobin level for adults?
The normal range for hemoglobin is: For men, 13.5 to 17.5 grams per deciliter. For women, 12.0 to 15.5 grams per deciliter.
Why are hemoglobin levels different in males and females?
The sex difference in mean venous haemoglobin levels and red cell mass is generally considered to be caused by a direct stimulatory effect of androgen in men in the bone marrow in association with erythropoietin, a stimulatory effect of androgen on erythropoietin production in the kidney, and an inhibitory effect of ...
Why do infants have more red blood cells than adults?
The problem may be caused by one of the following: The baby's body makes more red blood cells than it should. The baby got extra red blood cells from another source, such as from a twin during pregnancy. Just after birth, too many red blood cells traveled from the umbilical cord to the baby before the cord was clamped.
What is childhood anemia?
Page Content. Anemia is a condition in which the amount of red blood cells in the body is decreased below normal for your child's age. It can make your child appear pale in color and feel cranky, tired, or weak.
What is a normal hemoglobin level for a 16 year old female?
The reference ranges for hemoglobin (Hb) concentrations in adults are as follows : Male: 14-18 g/dL or 8.7-11.2 mmol/L (SI units) Female: 12-16 g/dL or 7.4-9.9 mmol/L (SI units)
Why hemoglobin is low in females?
Factors that can lower your body's stores of iron include the following: Blood loss (caused by ulcers, trauma, some cancers, and other conditions; and, in women, during monthly periods) An iron-poor diet. An increase in the body's need for iron (in women during pregnancy)
Is 10.5 hemoglobin bad?
A “normal” level of hemoglobin is usually in the range of 14-17gm/dL for men, and 12-15gm/dL for women. However, different laboratories may define the normal range slightly differently. A low hemoglobin level — meaning, it's below normal — can be used to detect anemia.
What is a critical hemoglobin level?
An Hb value less than 5.0 g/dL (50 g/L) can lead to heart failure and death. A value greater than 20 g/dL (200 g/L) can lead to obstruction of the capillaries as a result of hemoconcentration.
Is anemia more common in males or females?
Overall, anemia is twice as prevalent in females as in males. This difference is significantly greater during the childbearing years due to pregnancies and menses. Approximately 65% of body iron is incorporated into circulating Hb.
Can you tell the difference between male and female blood?
Compared to female blood, male blood had higher viscosity and RBC aggregation and lower RBC deformability. Oxygen Delivery Index, calculated as a ratio of hematocrit to blood viscosity, was found to be significantly lower in male blood.
Why does hemoglobin fluctuate?
Many factors can produce hemoglobin fluctuations in the same individual and in a group of individuals. Hemoglobin may decrease as much as 1 gm/dL with bed rest. Changes in fluid balance may affect plasma volume and therefore hemoglobin concentration. Gender and age are responsible for important normal variations.
