You could have a dating scan without NT screening, or even change your mind on the day of your scan. Most units offer a screening test for Down's syndrome and other conditions at the same time as the dating scan. Screening for Down's syndrome involves a nuchal translucency (NT) scan plus a blood test. You can have the combined screening test from 11 weeks to 13 weeks plus six days, or when your baby's CRL is 45mm (1.8in) to 84mm (3.3in). A blood test at what you thought was 13 weeks wouldn't be helpful if you were actually 16 weeks pregnant.
