Risk assessment following cfDNA testing / NIPT

There is now an official recommendation from the International Society of Ultrasound in O&G  (please see the following link to the ISUOG recommendation stating that when a 11-14 weeks scan is performed after cfDNA  / non-invasive prenatal testing results are available,  risk calculation for trisomies 21, 18 and 13 should not be issued. 

All components of the ultrasound risk assessment (NT / NB / DV) should be recorded as per routine practice in your centre. These markers should be clearly reported as per usual practice in the final ultrasound report.

Audit Data

The data can only be submitted for audit if there is a T21 risk calculated. For patients who have had cfDNA screening (NIPT), the T21 risk needs to be calculated to facilitate audit.

Viewpoint users may calculate the risks for audit purposes only by ticking the boxes at the bottom of the risk calculation page so that risks are not printed in the final report- please see screen shot below.  



If you are not sure how to activate this option on your Viewpoint software, please call Viewpoint /GE on 1 800 647 855.

If you use Astraia software, please contact the NTUEMP office to discuss options.
