what does having the sickle cell trait mean?

If an individual has sickle cell trait, it means that he or she carries or has inherited a single copy of the gene that causes sickle cell disease. It is not a disease. In general, people with sickle cell trait enjoy normal life spans with no medical problems related to sickle cell trait.

A sickle cell prep is a screening test done on blood to find if sickle cell trait or sickle cell disease is present. Sickle cell trait or disease happens when an abnormal hemoglobin (heem-uh-glo-bun) called hemoglobin S is in the blood.

- Sickle Cell Disease. When the hemoglobin S gene is inherited from only one parent, and a normal hemoglobin gene—hemoglobin A—is inherited from the other, that person will have sickle cell trait. People who have sickle cell trait are generally healthy.

What Is Sickle Cell Trait? Sickle cell trait (SCT) is not a disease, but having it means that a person has inherited the sickle cell gene from one of his or her parents. People with SCT usually do not have any of the symptoms of sickle cell disease (SCD) and live a normal life.

What is a sickle cell test? A sickle cell test is a simple blood test used to determine if you have sickle cell disease (SCD) or sickle cell trait. People with SCD have red blood cells (RBCs) that are abnormally shaped. Sickle cells are shaped like a crescent moon. Normal RBCs look like doughnuts.

Sickle Cell Disease and Sickle Cell Anaemia. Sickle cell disease (SCD) is a serious, inherited condition affecting the blood and various organs in the body. It affects the red blood cells, causing episodes of sickling, which produce episodes of pain and other symptoms.

Specialty. Hematology. Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous).

Sickle cell disease affects blacks almost exclusively. About 10% of blacks in the United States have one copy of the gene for sickle cell disease (that is, they have sickle cell trait).

Genetic Factors Persons who have the sickle cell trait (heterozygotes for the abnormal hemoglobin gene HbS) are relatively protected against P. falciparum malaria and thus enjoy a biologic advantage.

Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body.

They don't have enough sickle hemoglobin for the cells to become sickleshaped easily. Sickle cell trait is NOT a disease and will never turn into a disease. People with sickle cell trait usually do not have any health problems.

Sickle cell trait is an inherited blood disorder that affects 1 million to 3 million Americans and 8 to 10 percent of African Americans. Sickle cell trait can also affect Hispanics, South Asians, Caucasians from southern Europe, and people from Middle Eastern countries.

If a person has one copy of the sickle cell allele, half of their red blood cells will be misshapen. In this way, the allele is codominant, since both normal and sickled shapes are seen in the blood. But the allele can sometimes look recessive too.

Sickle cell disease is a condition in which red blood cells are not shaped as they should be. Red blood cells usually look like round discs. But in sickle cell disease, they're shaped like crescent moons, or an old farm tool known as a sickle.

Sickle cell disease (SCD) is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells.

On the contrary, individuals who are carriers for the sickle cell disease (with one sickle gene and one normal hemoglobin gene, also known as sickle cell trait) have some protective advantage against malaria. As a result, the frequencies of sickle cell carriers are high in malaria-endemic areas.

The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene. This means that you must have two copies of the recessive allele — one from your mother and one from your father — to have the condition.
