What to expect from your test result


Once the analysis is complete, your physician will share your results with you. It is important to remember that the Harmony test, like any screening test, does not provide a diagnosis. Most women receive a “low probability” result, meaning that the test did not find evidence of specific chromosome conditions. Some women receive a “high probability” result, meaning that a larger or smaller amount of DNA than expected from a specific chromosome was found. A “high probability” result does not necessarily mean that the fetus has a chromosome condition. A small proportion of women receive a report stating that a probability assessment could not be provided. These women may elect a second blood draw. All results should be discussed with a healthcare provider.
