CAUTION:

X

To calculate the GA and the EFW by measuring a specific part of a fetus, an accurate reference

must be selected.

X

If the EFW Reference of the UGEO PT60A is changed, the existing EFW is recalculated with the

new reference and then shown on the report. Therefore, it is recommended that you do not

change the EFW Reference of a patient.

X

Since multiple GAs and EFW References are provided, the specialist must make a choice based

on his or her clinical judgment. Choosing an inappropriate reference may result in incorrect

measurements.

X

When performing an exam, one must bear in mind that measurements may vary depending on

the posture of the fetus.

X

In cases where there are multiple fetuses, be sure to verify the Fetus ID to avoid confusion.

X

The GA and EFW Reference possess national and regional characteristics, which must be taken

into consideration when selecting a reference.
