Misconception of ECS
Several questions were designed to assess whether participants with intention of ECS had possible misconceptions. As shown in Table 4, when we asked whether ECS can rule out children with Down’s syndrome, only 3.5% answered correctly. Regarding the statement about negative screening results, only 29.9% agreed with the statement that negative results will not exclude a severe genetic child. When questioned if they were a carrier, 17.6% would feel unhealthy and 22.0% will feel stressed or discriminated against. When asked if the cost were the same, up to 86.7% chose the bigger panel (Table S2).
