Rank Info. Method
Specify how Growth Range is displayed. You can use Growth Range to check the development state
and normality of a fetus.
X Percentile: Shows the development progress of a fetus in percentage. You can check the
development state and normality of a fetus in relation to the reference development state of
50%.
X Standard Deviation: Uses international standard deviation to show the development state
of a fetus. You can check the development state and normality of a fetus in relation to the
reference development state of SD = 0.
X Bar (Graph): Shows percentiles in a bar graph. This option is available for OB reports only. The
green range represents a normal development state, and the red range after/before the green
range represents an abnormal development state.
Fetal Weight Unit
Specify the fetal weight unit that will be used for OB measurements. Specify this value in primary and
secondary units so that measurement results can be represented in various units. Valid primary units
are Gram [g] and lb +oz. The secondary unit can be selected from units available on the right. The unit
that is specied as the primary unit may not be selected as the secondary unit.
lb +oz is a unit representing pounds and ounces. None indicates that no primary unit is used.
