Rules according to the Confidetial enquiry into Stillbirths and Deaths in infancy (UK) Programme written by DJR Hutchon copyright. Translation by Razvan Socolov MD PhD Iasi- Romania. Requires Internet Explorer 4.0 or above (or eqivalent) for calculator to work. Year 2000 compliant. If Serum screen or nuchal thickness not available, (or less than 1 mm) leave blank. Only valid for calculating Down risk for CRL 38 - 84mm These calculations assume that the NT measurements are made using the same protocol as the Fetal Medicine Foundation. Instructions for using OFFLINE

Gestation by scan on date is wks +days.

Evaluarea starii fatului - sistem expert

Introdu data ecografiei, masuratori, IAmn si IR ombilical daca sunt disponibile

Zona normala a scorului Z e -1.645 la +1.645. Daca exista doar doua masuratori, introdu amanuntele în a doua si a treia coloana. Normal range for Z score is -1.645 to +1.645. This calculator is for educational use. It is believed accurate but no responsibility for accuracy of the results is accepted by the author.
