Hemoglobin is the iron-containing protein in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. A hemoglobin test measures the amount of hemoglobin in your blood.
A hemoglobin test is usually done as part of a complete blood count (CBC). A CBC measures the concentration of white blood cells, red blood cells, and platelets in your blood and can give your doctor important information about your general health and well-being.
A hemoglobin test is generally recommended for people who have symptoms of anemia, such as fatigue or shortness of breath. Your doctor may also recommend a hemoglobin test if you have a history of heart disease, kidney disease, or other conditions that can cause anemia.
A hemoglobin test is usually ordered to check for anemia or, more specifically, to determine how much oxygen is being carried in the blood. It can also be used to screen for certain types of hereditary disorders, such as sickle cell disease or thalassemia.
The results of a hemoglobin test can help to diagnose various conditions, such as anemia, iron deficiency, and sickle cell disease. In some cases, the test may also be used to monitor treatment for these conditions.
To do the test, a healthcare provider will take a small sample of blood from your arm and send it to a lab for analysis. The results of the test will be available within a few days.
To prepare for a hemoglobin test, your healthcare provider may tell you to:
- Fast for 8 hours before the test
- Avoid smoking or using tobacco products for at least 30 minutes before the test
- Avoid drinking alcohol for at least 24 hours before the test.
The Hemoglobin Test Results usually take about 2 to 3 days. However, if the test results are needed urgently, the results can be released within 24 hours.
