Z-Score Tables
Boston Congenital Module
Clinical Reporting Application (CRA) calculates congenital normative data for many common measurements and calculations. The following tables provide definitions of the values for the available normative data, as well as their valid limits.
|
Note: |
|
CRA requires the patient’s age and BSA in order to generate normative data for a congenital measurement or calculation. The body surface area is based on the method published by Haycock, Schwartz, and Wisotsky (height is assumed to be in centimeters and weight in kilograms).
BSA = 0.024265 * (0.3964 * Height) * (0.5378 * Weight)

Boston Fetal Module
Clinical Reporting Application (CRA) calculates fetal normative data for several common measurements and calculations. The following table provides definitions of the values for the available normative data, as well as their valid limits.
- CRA requires the GA to generate fetal normative data for a measurement or calculation. The Gestational Age (GA) is determined from the Estimated Date of Confinement (EDC).
