![]() If it falls within the standard range, the result will be “negative.” This means the fetus has a decreased risk of the genetic conditions caused by the chromosomes in question. The test will look at specific chromosomes to see if the percentage of cfDNA from each of these chromosomes is considered “normal.” The most common way is to determine the amount of both maternal and fetal cfDNA. There are several ways the fetal cfDNA can be analyzed. This usually happens around the 10th week of pregnancy and this is why the test is recommended after this time. For the most accurate test results possible, the fetal fraction must be over 4 percent. The NIPT measures the fetal cfDNA in the mother’s bloodstream, which comes from the placenta. Understanding what the NIPT test results mean Yes, this prenatal test can reveal your baby’s sex in the first trimester - earlier than any ultrasound! On the positive side, cfDNA also holds the answer to a big question: whether you’re carrying a boy or a girl. It can, however, predict whether the risk of a genetic condition is high or low. This means that it can’t diagnose a genetic condition with certainty. It’s important to know that NIPT is a screening test - not a diagnostic test. cfDNA is created when these cells die and are broken down, releasing some DNA into the bloodstream. The blood test looks at tiny pieces of cell-free DNA (cfDNA) from the placenta that are present in a pregnant woman’s blood. Most commonly, the test determines the risk of disorders such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13), as well as conditions caused by missing or extra X and Y chromosomes. By 10 weeks of pregnancy, your healthcare provider may talk to you about this elective test as an option to help identify if your baby is at risk for genetic abnormalities, such as chromosomal disorders. ![]() ![]() The NIPT prenatal test is sometimes called the noninvasive prenatal screen (NIPS). ![]()
