The ultrasound screening was completed and everything is fine. However, I ate a lot of salads, drinks, cake, etc., on my birthday night. In the morning, I went to have blood drawn, and the results came back positive for T21 risk 1:400. They determined my age as 33. The geneticist suggested that I take a NIPT or amniocentesis test. However, I found out about Prenatal Screening Triamniotic 2 trimesters in Vitro. PRISCA-2 (Biochemical screening 2 trimesters, "Triple Test" 2 trimesters, risk calculations using the PRISCA program). Who had this done?
