Harmony test (by Roche)

The Harmony test by Roche is a non-invasive prenatal screening that analyzes cell-free DNA from a pregnant woman's blood to assess the risk of fetal chromosomal conditions, such as Down syndrome (trisomy 21) and others. By examining fragments of DNA from the fetus that circulate in the mother's bloodstream, the test provides insights into the likelihood of these conditions without posing any risk to the baby. It is typically offered after the 10th week of pregnancy and helps expectant parents make informed decisions about further diagnostic testing or management.
