What does hemoglobin S indicate?
What does hemoglobin S indicate?
Hemoglobin S trait, also know as sickle cell trait, means that your child has inherited one gene for the usual hemoglobin (A) from one parent and one gene for hemoglobin S from the other parent. Hemoglobin S or sickle cell trait is very common and does not. cause any health problems.
What does high hemoglobin S mean?
Collapse Section. Sickle cell disease is a group of disorders that affects hemoglobin , the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle , or crescent, shape …
What is a normal hemoglobin electrophoresis result?
Normal Results 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)
Which hemoglobin electrophoresis findings suggest sickle cell disease SCD )?
In children with normocytic hemolytic anemia, if results of electrophoresis show only HbS with an HbF concentration of less than 30%, the diagnosis is sickle cell anemia. If HbS and HbC are present in roughly equal amounts, the diagnosis is HbSC disease.
What causes hemoglobin S?
Hemoglobin S results from the inherited substitution of valine for glutamic acid as the sixth amino acid of the beta globin chain. This change produces profound alterations in the stability and solubility of the hemoglobin molecule.
Can hemoglobin S carry oxygen?
Hemoglobin is a protein that allows red blood cells to carry oxygen to all parts of the body. The severity of these rarer types of SCD varies.
What is Hb SS disease with crisis?
Sickle chest syndrome is a severe type of sickle cell crisis. It causes severe chest pain and is associated with symptoms such as cough, fever, sputum production, shortness of breath, and low blood oxygen levels.
How do you interpret hemoglobin electrophoresis results?
Hemoglobin electrophoresis is used as a screening test to identify normal and abnormal hemoglobins and assess their quantity….Adult/elderly: Percentage of total Hb :
- HbA 1: 95-98%
- HbA 2: 2-3%
- HbF: 0.8-2%
- HbS: 0%
- HbC: 0%
- HbE: 0%
What is hemoglobin electrophoresis test?
Hemoglobin electrophoresis is the process healthcare providers use to analyze hemoglobin in your red blood cells. Hemoglobin electrophoresis helps diagnose serious conditions like sickle cell anemia. It’s also one of several tests that screen newborn babies for sickle cell anemia and other rare but serious illnesses.
Where is hemoglobin S most common?
The gene for Hemoglobin S has the highest frequency among people of African heritage (about 1 in 10). However, it is also found in people of Hispanic and Mediterranean (Italian, Greek, and Turkish) descent.
What is the difference between hemoglobin S and hemoglobin A?
Hemoglobin S: The most common type of abnormal hemoglobin and the basis of sickle cell trait and sickle cell anemia. Hemoglobin S differs from normal adult hemoglobin (called hemoglobin A) only by a single amino acid substitution (a valine replacing a glutamine in the 6th position of the beta chain of globin).

What is a normal serum hemoglobin level?
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; Normal ranges for children vary with age and sex. The range for a normal hemoglobin level may differ from one medical practice to another. Lower than normal results. If your hemoglobin level is lower than normal, you have anemia.
What does gel electrophoresis mean?
Gel electrophoresis is a type of biotechnology that separates molecules based on their size to interpret an organism’s DNA. An enzyme is used to separate a strand of DNA from a source and the DNA is suspended in a dye. Then, the dye is applied to a negatively-charged gel on one side of a sheet.
What is the function of sickle cell hemoglobin?
Types of SCD. People who have this form of SCD inherit two sickle cell genes (“S”),one from each parent.
