a
The Gestational Age is automatically calculated and displayed next to the Obstetrical measurement you selected. The average of
the results is the AUA. Only measurements of the same type are averaged
b
For Tokyo U., APTD and TTD are used only to calculate EFW. No age or growth tables are associated with these measurements
c
The Estimated Fetal Weight (EFW) calculation uses an equation that consists of one or more fetal biometry measurements. The
author for the Obstetrical tables, which you choose on a system setup page, determines the measurements you must perform to
obtain an EFW calculation. Individual selections for Hadlock's EFW equations 1, 2, and 3 are not determined by the user. The
selected equation is determined by the measurements that have been saved to the patient report with priority given to the order
listed above.
d
The Growth Analysis tables are used by the Report Graphs feature. Three growth curves are drawn using the table data for the
selected growth parameter and published author. Growth tables are available only with a user-entered LMP or EDD
