Know your sickle cell trait status.
Enroll with us in a few easy steps
Sickle cell disease (SCD) is a group of red blood cell disorders. It can affect the shape of certain blood cells. The sickle cell trait gene is inherited. That means parents can pass it down to their child, just like the color of eyes, skin and hair. People with the sickle cell trait (SCT) have one sickle cell gene and one normal gene. They usually don’t have any SCD symptoms. But people with SCT can pass the trait to their children.
What is sickle cell trait (SCT)?
- SCT means that a person has the sickle cell gene passed from one of their parents. SCT is shown with a simple blood test.
- About 3 million people in the U.S. have SCT. Many are unaware they have it.
- Most people don’t have any symptoms of SCD, but some people with SCT may have complications like a pain crisis.
- Both parents need to carry the SCT gene for a child to have SCD.
- If you and your partner carry the SCT, there’s a 25% chance your child will have SCD. There is a 50% chance for your child to be a carrier.1
Knowing your SCT status can help you:
- Make family planning choices, like genetic counseling, prenatal testing and getting ready for a child with SCD, if needed
- Get the right medical care for things like pregnancy, kidney issues, heart disease or eye problems, and keep up with routine lab tests
- Manage the risk factors you can control, like pregnancy, obesity or smoking
- Be ready for lifestyle risks, like not having enough water, or low oxygen levels when you do intense activities1
