The displayed result is labeled because the composite ultrasound age (CUA). In addition, the machine will automatically common all the biometric measurements (AC, BPD, FL, and HC), labeling the result as the arithmetic ultrasound age (AUA). In 1984, Hadlock et al in contrast their CUA formula with the AUA and found no important variations between the 2.1 This has not been done with the model new NICHD formula, however the CUA is more probably to be similar to the AUA. The NICHD formula carried out no higher than the Hadlock formula between 14 to twenty weeks (± 7 days). However, it was slightly higher at 21 to 27 weeks (± 10 days), with a mean “estimation error” (EE) of 10.four vs. 11.2 days.
