Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
Each year about 300,000 infants are born with major sickle-cell disorders—including more than 200,000 cases in Africa A 10-minute test could solve Africa’s sickle cell disease screening ...
Lovotibeglogene autotemcel, sold under the brand name Lyfgenia, is a lentiviral gene therapy used for the treatment of sickle cell disease. [1] [3] [4] [5]The most common side effects include stomatitis (mouth sores of the lips, mouth, and throat), low levels of platelets, white blood cells, and red blood cells, and febrile neutropenia (fever and low white blood cell count), consistent with ...
an increased production of HbS as seen in sickle cell disease (not sickle cell trait); an increased destruction or loss of red blood cells (e.g., hemolysis, posthemorrhagic anemia, hypersplenism); an uncompensated increase in plasma volume (e.g., pregnancy, fluid overload); a B2 deficiency [3] a B6 deficiency [3]
A study published in 2021 found that 50% of sickle cell patients reported having to wait at least two hours before their pain was treated, despite medical guidelines recommending such patients in ...
Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.

Testing HbA2 levels can be challenging because different disorders can cause it to have higher or lower values. Testing for the beta-thalassemia trait is usually identified when the value of HbA2 is higher than 3.5%. [3] HbA2 is also important for diagnosing sickle cell disease, which is one of the most prevalent genetic conditions.
