Clinical Info

1T Aneuploidy Screen is a first trimester screening test for the three most common fetal aneuploidies, trisomies 21, 18 and 13.  
The test incorporates the maternal serum markers AFP, free βhCG, Inhibin A, PAPP-A  and PlGF and the fetal ultrasound markers 
nuchal translucency (NT) and nasal bone (NB -optional)  An increased risk result means that further screening
(ultrasound, NIPT) and/or diagnostic testing (amniocentesis) may be offered.
