Clinical Info

2T Sequential Screen combines a
patient’s previous 1T Aneuploidy screen with a second trimester QUAD Screen to
test for the two most common fetal aneuploidies, trisomies 21 and 18.  2T Sequential screen measures maternal serum
AFP, Free beta hCG, Inhibin A and uE3 then combines the results with the
patients first trimester PAPP-A, 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
