What is sickle Haemoglobin?

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 the meaning of sickle cells?

(SIH-kul sel dih-ZEEZ) An inherited disease in which the red blood cells have an abnormal crescent shape, block small blood vessels, and do not last as long as normal red blood cells.

What is the difference between hemoglobin and sickle cell hemoglobin?

Red blood cells with normal hemoglobin are smooth, disk-shaped, and flexible, like doughnuts without holes. They can move through the blood vessels easily. Cells with sickle cell hemoglobin are stiff and sticky. When they lose their oxygen, they form into the shape of a sickle or crescent, like the letter C.

What is a sickle cell test called?

The best way to check for sickle cell trait or sickle cell disease is to look at the blood using a method called high-performance liquid chromatography (HPLC). This test identifies which type of hemoglobin is present. To confirm the results of HPLC, a genetic test may be done.

What’s the difference between SC and SS?

Hemoglobin SC disease is the second most common type of sickle cell disease. It occurs when you inherit the Hb C gene from one parent and the Hb S gene from the other. Individuals with Hb SC have similar symptoms to individuals with Hb SS. However, the anemia is less severe.

What is the difference between sickle cell disease and sickle cell Anaemia?

Sickle cell disease (SCD) is a serious group of conditions which are inherited (genetic). It affects the red blood cells in the blood. Sickle cell anaemia is the name of a specific form of SCD in which there are two sickle cell genes (see below).

What is the hemoglobin level for sickle cell anemia?

People with normal hemoglobin usually have a hemoglobin level around 12 g/dL. People with sickle cell disease have lower hemoglobin levels, usually between 6–11 g/dL.

What does hemoglobin S stand for?

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.
