Hemoglobin HB measures how much hemoglobin is in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen to your body’s organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. HB is composed of a protein called heme, which binds oxygen.
Both low and high values can indicate disease states. Hemoglobin is the most important component of red blood cells. It is composed of a protein called home, which binds oxygen.
Your red blood cells carry oxygen throughout your body. If you have a condition that affects your body’s ability to make red blood cells, your hemoglobin levels may drop. Low hemoglobin levels may be a symptom of several conditions, including different kinds of anemia and cancer.
How the test Performed
A blood sample is needed.
How to prepare a test
No special Preparation
What is it used for
Hemoglobin is used to check anemia. If you have anemia, the cells in your body don’t get all the oxygen they need. The hemoglobin test is always done as a part of a Complete Blood Count (CBC). The reason and condition for ordering the hemoglobin test is
- Before and after the surgery
- Blood in your stool
- Chronic medical problems,
- Kidney disease and kidney failure
- Fatigue,
- During Pregnancy,
- Poor Health
- Headaches
- Symptoms of anemia
- A long-term infection
- Leukemia
- Bleeding (Mouth, Nose, Anus)
- Pails
- Blood loss from injuries
- Problem Concentrating
Results:
For Men: 13.2 to 16.6 g/dL
For Women: 11.6 to 15.0 g/dL
Normal results for children vary, but in general are:
- Newborn: 14 to 24 g/dL or 140 to 240 g/L
- Infant: 9.5 to 13 g/dL or 95 to 130 g/L
Lower Than Normal Result Means
If you have hemoglobin level is lower than normal there are many forms of anemia.
- Iron deficiency
- Vitamin B-12 Deficiency
- Bleeding
- Kidney Dieses
- Liver Dieses
- Thalassemia
- Leukemia
- Hypothyroidism
Higher Than Normal Result Means
If your hemoglobin is higher than normal it may be the result of
- Lung disease
- Dehydration
- Living at a high altitude
- Polycythemia
- Burns
- Excessive vomiting
- Low levels of oxygen in the blood
