What is a normal hematocrit for a male?
What is a normal hematocrit for a male?
The definition of normal red-blood cell percentage also varies from one medical practice to another. Generally, a normal range is considered to be: For men, 38.3 to 48.6 percent. For women, 35.5 to 44.9 percent.
What is a good hemoglobin level for a man?
Results. 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.
What is the relationship between hematocrit and hemoglobin levels?
Hemoglobin is the iron-based molecule type that gives blood its red color and ferries oxygen to the rest of the body. Hemoglobin is a protein in red blood cells and hematocrit is a measurement of the amount of red blood cells as related to total blood cell count.
What are the acceptable hemoglobin and hematocrit for a male donor?
Male allogeneic donors must have a hemoglobin level that is equal to or greater than 13.0 g/dL, or a hematocrit value that is equal to or greater than 39%. An autologous donor must have a hemoglobin level no less than 11.0 g/dL, or a hematocrit value no less than 33%.
What does a low hemoglobin and hematocrit mean?
Low Hgb is also known as anemia, which means that you don’t have enough red blood cells in your body. With anemia, a blood test will also show that you have a low red blood cell count and may have low hematocrit, the volume of red blood cells to other components in your blood.
What causes elevated hemoglobin and hematocrit?
A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there.
What happens if hemoglobin and hematocrit are low?
Why is my hemoglobin and hematocrit low?
Low RBC counts, hemoglobin and hematocrit levels can be caused by other things too, such as a lot of bleeding or malnutrition (not enough nutrients in the food eaten). Kidney disease, liver disease (cirrhosis), cancer, and medications used to treat cancer can also cause low levels.
What is the minimum hemoglobin level for blood donation?
The NIH Blood Bank and Platelet Center check your hemoglobin level before every blood donation to ensure you meet the minimum requirements for blood donation. Female blood donors must have a hemoglobin level of at least 12.5 g/dL and male blood donors must have a hemoglobin level of at least 13.0 g/dL.
Can a person with low hemoglobin donate blood?
If your haemoglobin level is less than the cut-off value, you will not be able to donate blood until the time you have further tests to know the reason for your low haemoglobin, receive treatment for the condition and have a normal haemoglobin value above the cut-off level.
