Chapter 5 Measurements and Calculations

Tips!

SD and Percentile are interchangeable. Percentile can be used when a fetal measurement ranking is

desired, and SD can be used when the distance between actual fetal measurements and the average

measurement is sought.

While the range of Growth Table references that are primarily used with OB measurement data varies

depending on the user, the typical range accepted by most users is as below:

1) When references are created based on SD:

X

2.0 SD - +2.0 SD (when converted to Percentile: 2.28 Percentile - 97.72 Percentile)

X

1.5 SD - +1.5 SD (when converted to Percentile: 6.68 Percentile - 93.32 Percentile)

X

1.0 SD - +1.0 SD (when converted to Percentile: 15.87 Percentile - 84.13 Percentile)

2) When references are created based on Percentile:

X

2.5 Percentile - 97.5 Percentile (when converted to SD: -1.96 SD - 1.96 SD)

X

5.0 Percentile - 95.0 Percentile (when converted to SD: -1.645 SD - 1.645 SD)

X

10.0 Percentile - 90.0 Percentile (when converted to SD: -1.288 SD - 1.288 SD)
