For men, a normal level ranges between 14.0 grams per deciliter (gm/dL) and 17.5 gm/dL. For women, a normal level ranges between 12.3 gm/dL and 15.3 gm/dL. A severe low hemoglobin level for men is 13.5 gm/dL or lower. For women, a severe low hemoglobin level is 12 gm/dL.
A low hemoglobin count is generally defined as less than 13.2 grams of hemoglobin per deciliter (132 grams per liter) of blood for men and less than 11.6 grams per deciliter (116 grams per liter) for women. In children, the definition varies with age and sex.
Anemia can be defined as a reduction in hemoglobin (less than 13.5 g/dL in men; less than 12.0 g/dL in women) or hematocrit (less than 41.0% in men; less than 36.0% in women) or red blood cell (RBC) count.
You can raise your hemoglobin levels by eating more foods that have iron, like poultry, meat, tofu, and leafy greens like spinach and kale. If your hemoglobin level is particularly low, your healthcare provider may recommend iron supplements or iron therapy.
The amount of hemoglobin in whole blood is expressed in grams per deciliter (g/dl). The normal Hb level for males is 14 to 18 g/dl; that for females is 12 to 16 g/dl. When the hemoglobin level is low, the patient has anemia.
For the majority of healthy individuals, normal blood sugar levels are as follows: Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting [361] Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating.
For all of the tested groups, moderate anemia corresponds to a level of 7.0-9.9 g/dl, while severe anemia corresponds to a level less than 7.0 g/dl.
Call Your Doctor About Anemia If:
Persistent fatigue, breathlessness, rapid heart rate, pale skin, or any other symptoms of anemia; seek emergency care for any trouble breathing or change in your heart beat.
Normal Results
Normal value range is: Iron: 60 to 170 micrograms per deciliter (mcg/dL), or 10.74 to 30.43 micromoles per liter (micromol/L)
Too little iron in the body causes this most common type of anemia. Bone marrow needs iron to make hemoglobin. Without enough iron, the body can't make enough hemoglobin for red blood cells.
Fatigue. Tiring easily, and waking up tired even after a good night's sleep, are common and potentially serious symptoms of anemia. This is due to reduced and compromised red blood cells that naturally cannot carry the required levels of oxygen to the organs – which, in turn, cannot function efficiently.
A severe low hemoglobin level for men is 13.5 gm/dL or lower. For women, a severe low hemoglobin level is 12 gm/dL.
“Anemia cannot cause leukemia but could be a sign of bone marrow that's not producing enough red blood cells,” Dr. Wetmore explained. “This requires an investigation (lab tests) into the cause of low numbers of red blood cells.”
Some foods can make it harder for your body to absorb iron. These include coffee, tea, milk, egg whites, fiber, and soy protein. Try to avoid these foods if you have iron deficiency anemia.
adult will have approximately 1.2-1.5 gallons (or 10 units) of blood in their body. Blood is approximately 10% of an adult's weight.
Definitions of massive blood loss vary. = loss of one blood volume within a 24 hr period.
Blood sugar levels change often during the day. When they drop below 70 mg/dL, this is called having low blood sugar.
