We went Evanston Northwestern Hospital for our BUNN test. It is a ultrasound that measures the clear space in the folds of tissue behind a developing baby's neck. This measurement, taken together with the mother's age and the baby's gestational age, can be used to calculate the odds that the baby has Down Syndrome. They also do a blood test in conjunction with the ultra sound to get a better accuracy for Down Syndrome."Cashew"
