Fetal Growth Restriction Severity Staging (Careggi/ACOG)

Stage fetal growth restriction (FGR) severity using Doppler parameters and BPP to guide delivery timing. Stage 1-4 framework: from EFW below 10th percentile with normal Doppler (Stage 1) to reversed DV A-wave or abnormal BPP (Stage 4).

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Stage fetal growth restriction (FGR) severity using Doppler parameters and BPP to guide delivery timing. Stage 1-4 framework: from EFW below 10th percentile with normal Doppler (Stage 1) to reversed DV A-wave or abnormal BPP (Stage 4)

Each component has a specific meaning:

  • Doppler parameters — The doppler parameters recorded for the scenario being assessed.
  • BPP — The bpp recorded for the scenario being assessed.

Note: Interpret the fgr staging result against the thresholds and context described above.

How to Use

Enter the Doppler parameters, BPP for the scenario you are assessing. Stage fetal growth restriction (FGR) severity using Doppler parameters and BPP to guide delivery timing. Stage 1-4 framework: from EFW below 10th percentile with normal Doppler (Stage 1) to reversed DV A-wave or abnormal BPP (Stage 4). Use the fgr staging result to inform your calculation.
