Hi Doc, I am 16 weeks
pregnant. My NTNB was done when I was 13 weeks and 3 days as per LMP but as per USG I was 14 weeks at time of NTNB. Are the results of NTNB reliable at 14 weeks ( as per USG). The NT value was 1.2 mm and NB was 2.4 mm. Secondly, As the results of NTNB are okay, do I still need to get Quadruple marker test done.
Many thanks for the support.
