At 11 weeks pregnant , nuchal translucency was 1.26. Other results were fine. Because of maternal age on higher side at 39, doc had suggested NIPT at 11 -12 weeks itself. Results are low risk for all categories. Now at 19 weeks i have done anomaly scan. All parameters normal. But nuclear fold is thick at 6.5m. If NIPT is fine, does the thick at 6.5m be a cause to worry? Do NIPTs need to be redone?
