The oxygen-carrying protein found in the red blood cells is known as hemoglobin. This protein provides the red color to the blood. It carries oxygen from the lungs to the body tissues and transports carbon dioxide to the lungs from the tissues. The amount of oxygen present in the blood is measured by the hemoglobin test.
What does the hemoglobin test reveal?
The hemoglobin test reveals whether your blood has a lower hemoglobin count than normal, then it means you have anemia. The hemoglobin plays an important role in shaping up the red blood cells. The decrease in the hemoglobin normal count causes the change in the shape of the red blood cells.
The low hemoglobin level or anemia can lead to heart palpitations, fatigue, hair loss, shortness of breath, and feeling of wellness. The causes of anemia include nutritional deficiency, bone marrow problems, kidney failure, chronic disease, and an excessive amount of blood loss.
The high hemoglobin level is basically seen in the people who are living in the high-altitude areas, those who smoke a lot, and it happens due to the dehydration. When the body receives the proper amount of fluid then the normal hemoglobin levels are restored. Some other causes of the high hemoglobin are advanced lung disease, certain types of tumors, polycythemia (a disorder of the bone marrow), and due to drug abuse.
Why Hemoglobin Test is done?
Hemoglobin test can be done for several reasons such as:
The hemoglobin test is conducted as regular medical checkup which helps in monitoring general health conditions.
It also helps to diagnose various diseases.
if you have any symptoms of anemia or polycythemia such as dizziness, fatigue, weakness, and palpitations then the doctors suggest the patient should take a hemoglobin test.
If someone has a family history of genetic abnormalities such as thalassemia, sickle blood cells, or any other congenital disease then the doctor may prescribe you to take a hemoglobin test.
During any surgical treatment, if there is any excessive blood loss then also doctor prescribes for the hemoglobin test. As blood loss causes anemia.
What happens during the blood test?
Hemoglobin can be measured as a part of the Complete Blood Count (CBC) Test. The doctor will insert the needle in your veins and take a blood sample and collect the blood in a test tube. It will take a few minutes to collect the blood sample. The doctor will instruct you about the time of day you will get the test report.
What happens after the blood test report?
The test report can be in the range of three levels – normal haemoglobin level, high haemoglobin level, and low haemoglobin level. The haemoglobin level can be stated in gram (gm) per deciliter (dL) and a decilitre is a 100 millilitre.
The normal haemoglobin level ranges according to age and gender. The HB level in newborn baby is from 17 to 22 gm/dL. In children, 11 to 13 gm/dL. In adult males, 14 to 18 gm/dL and in adult females it ranges from 12 to 14 gm/dL.
If the haemoglobin level is less or more than that then there is a reason for that. Low haemoglobin level generally means anaemia. There are many reasons for anaemia which includes stomach ulcer, colon cancer, iron and vitamin deficiency, kidney failure, thalassemia, and usage of drugs. There are several ways to increase the HB level in the body such as increasing the intake of iron-rich food(eggs, vegetables, nuts, cereals, spinach, beans, meat, and seafood), taking iron supplements, and by transfusing blood cells. Ask for advice from the doctor that by which way you can increase the Hb in your body.
Polycythaemia is a disorder in which bone marrow produces more blood cells. There are few ways to reduce the HB level in the blood such as by reducing the intake of iron in your food, limit the intake of Vitamin C, and drink more water as dehydration is one of the common causes of elevated haemoglobin.
