Genetic screening: It appears that you are undergoing genetic screening. Typically the Nuchal fold is combined with blood testing to help determine the risk of genetic abnormalities. The impedance level through the ductus venosus is sometimes added as a screening tool. Schedule a follow up with your doctor to go over all of your results and so that your risk can be calculated
