Most babies are born healthy, but some may come into the world with health problems. These conditions can develop for a variety of reasons, ranging from genetic factors to complications during pregnancy or birth. While advances in prenatal care and testing can sometimes identify certain issues before delivery, not all health problems can be detected in advance. As a result, some conditions are only discovered after a baby is born.
Chromosomes carry our genetic information. Chromosomal conditions, like Down syndrome, caused by an extra or missing copy of a chromosome, do not usually run in families. They are not caused by anything a pregnant woman does or does not do before or during pregnancy.
Some things, such as a woman’s age, may increase the chance of having a pregnancy with a chromosomal condition. If a woman has already had a screening test for chromosomal conditions in her current pregnancy, her chances may be higher or lower.
Some pregnancies with a chromosomal condition end in pregnancy loss (miscarriage or stillbirth).
There is no single test that can guarantee a healthy baby, but there are testing options available during pregnancy for some common chromosomal conditions. This app provides information about those testing and screening options, and it can be especially helpful for women who are considering noninvasive prenatal testing (NIPT). In addition, your health specialist may recommend further testing for other types of conditions, depending on your individual situation.
Choose your age (or age of egg donor):
The chance of Down syndrome in a pregnancy at this age is: 13 out of 10,000. This means that of 10,000 women at this age, about 13 will have a pregnancy with Down syndrome and about 9987 will have a pregnancy without Down syndrome.
The chance of Down syndrome in a pregnancy at this age is: 16 out of 10,000. This means that of 10,000 women at this age, about 16 will have a pregnancy with Down syndrome and about 9984 will have a pregnancy without Down syndrome.
The chance of Down syndrome in a pregnancy at this age is: 29 out of 10,000. This means that of 10,000 women at this age, about 29 will have a pregnancy with Down syndrome and about 9971 will have a pregnancy without Down syndrome.
The chance of Down syndrome in a pregnancy at this age is: 83 out of 10,000. This means that of 10,000 women at this age, about 83 will have a pregnancy with Down syndrome and about 9917 will have a pregnancy without Down syndrome.
The chance of Down syndrome in a pregnancy at this age is: 322 out of 10,000. This means that of 10,000 women at this age, about 322 will have a pregnancy with Down syndrome and about 9678 will have a pregnancy without Down syndrome.
Please note: This indicates the age-related chance for Down syndrome at 10 weeks gestation. The chance for other chromosomal conditions is in addition to this chance. The chance for a chromosomal condition in your pregnancy may vary based on your family history, clinical history, and any previous screening results. Please speak to your health specialist for your specific chances.
