A hemoglobin electrophoresis test is a blood test done to check the different types of hemoglobin in the blood. Hemoglobin is the substance in red blood cells that carries oxygen. The most common types of normal hemoglobin are: Hemoglobin A. This is the most common type of hemoglobin found normally in adults.

In respect to this, Why electrophoresis test is done?

Hemoglobin electrophoresis measures hemoglobin levels and looks for abnormal types of hemoglobin. It's most often used to help diagnose anemia, sickle cell disease, and other hemoglobin disorders.

Likewise, people ask, When is hemoglobin electrophoresis done?. To diagnose blood disorders: Your doctor may have you do a hemoglobin electrophoresis test if you're showing symptoms of anemia. The test will help them find any abnormal types of hemoglobin in your blood. These could be a sign of disorders including: sickle cell anemia.

Similarly one may ask, What is normal hemoglobin electrophoresis?

In adults, these are normal percentages of different hemoglobin molecules: HbA: 95% to 98% (0.95 to 0.98) HbA2: 2% to 3% (0.02 to 0.03) HbE: Absent.

What is Hb electrophoresis test in pregnancy?

Hemoglobin electrophoresis is a blood test that measures different types of a protein called hemoglobin in your red blood cells. It's sometimes called “hemoglobin evaluation” or “sickle cell screen.” Newborns automatically get this test because it's the law.

What is electrophoresis used for?

Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores.

How do you interpret Hb electrophoresis results?

High and low values
  1. Higher-than-normal amounts of both hemoglobin A2 and hemoglobin F may mean a mild form of thalassemia is present. ...
  2. Hemoglobin S in moderate amounts can mean that sickle cell trait is present. ...
  3. Hemoglobin C in low amounts can mean that hemoglobin C trait is present.

Can thalassemia be cured?

Bone marrow and stem cell transplant from a compatible related donor is the only treatment that can cure thalassemia. It is the most effective treatment.

What are the 4 types of hemoglobin?

The most common types of normal hemoglobin are:
  • Hemoglobin A. This is the most common type of hemoglobin found normally in adults. ...
  • Hemoglobin F (fetal hemoglobin). This type is normally found in fetuses and newborn babies. ...
  • Hemoglobin A2. This is a normal type of hemoglobin found in small amounts in adults.

How can a blood test detect thalassemia?

Several laboratory tests may be used to help detect and diagnose thalassemia:
  1. Complete blood count (CBC). The CBC is an evaluation of the cells in the blood. ...
  2. Blood smear (also called peripheral smear and manual differential). ...
  3. Iron studies. ...
  4. Hemoglobinopathy (Hb) evaluation (hemoglobin electrophoresis).

How thalassemia test is done?

Doctors diagnose thalassemias using blood tests, including a complete blood count (CBC) and special hemoglobin tests. A CBC measures the amount of hemoglobin and the different kinds of blood cells, such as red blood cells, in a sample of blood.

What is the normal range of thalassemia?

Hematologic Diagnosis

Thalassemia major is characterized by reduced Hb level (<7 g/dl), mean corpuscolar volume (MCV) > 50 < 70 fl and mean corpuscolar Hb (MCH) > 12< 20 pg. Thalassemia intermedia is characterized by Hb level between 7 and 10 g/dl, MCV between 50 and 80 fl and MCH between 16 and 24 pg.

What is the principle of Haemoglobin electrophoresis?

Hemoglobin electrophoresis is done by placing a small amount of blood on special paper or a special gel and exposing it to an electrical current. Different globins have different electrical charges and can be differentiated from one another based on their behaviors when exposed to an electrical current.

How is electrophoresis done?

Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. An electric current is used to move molecules to be separated through a gel. Pores in the gel work like a sieve, allowing smaller molecules to move faster than larger molecules.

What does abnormal blood protein mean?

High blood protein (hyperproteinemia) is an increase in the concentration of protein in the bloodstream. High blood protein is not a specific disease or condition in itself, but it might indicate you have a disease. High blood protein rarely causes signs or symptoms on its own.

How long do thalassemia patients live?

“Most thalassaemia patients would live up to the age of 25 to 30 years. Improved facilities will help them live up to the age of 60,” said Dr Mamata Manglani, head of pediatrics, Sion hospital.

What are the two major types of thalassemia?

There are 2 main types of thalassemia: alpha and beta. Different genes are affected for each type. Thalassemia can cause mild or severe anemia.

Is thalassemia a serious disease?

A person with thalassemia will have too few red blood cells and too little hemoglobin, and the red blood cells may be too small. The impact can range from mild to severe and life-threatening. Around 100,000 newborns are delivered each year with severe forms of thalassemia.

What HB mean in blood?

Hemoglobin (Hb or Hgb) is a protein in red blood cells that carries oxygen throughout the body. A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women.

What is the distribution of normal Hb in adults?

Normal results for adults vary, but in general are: Male: 13.8 to 17.2 grams per deciliter (g/dL) or 138 to 172 grams per liter (g/L) Female: 12.1 to 15.1 g/dL or 121 to 151 g/L.

What is an abnormal hemoglobin?

Abnormal hemoglobins result from mutations that change the sequence or number of nucleotides within the globin gene involved, or more rarely, from mispairing and crossover between two like genes during meiosis, creating a fusion protein of both gene sequences.

Is fasting required for Hb electrophoresis?

preparations needed for haemoglobin (hb) electrophoresis test. No Fasting Required. No other special preparations required.

What is iron profile test?

Iron Profile is a panel of blood tests that check the level of iron in the blood. Iron Profile shows how much of the iron is stored in the tissues. Iron Profile includes Serum Iron (Fe), Total Iron Binding Capacity and % Transferrin Saturation.
