Ectopic Pregnancy MPA Prediction Score

Calculate ectopic pregnancy risk using serum β-hCG trend, progesterone, and ultrasound findings. Discriminatory β-hCG zone (1,500-3,500 IU/L) with absent intrauterine gestational sac increases ectopic probability. Guides methotrexate eligibility.

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

Calculate ectopic pregnancy risk using serum β-hCG trend, progesterone, and ultrasound findings. Discriminatory β-hCG zone (1,500-3,500 IU/L) with absent intrauterine gestational sac increases ectopic probability. Guides methotrexate eligibility

Each component has a specific meaning:

  • Serum β-hCG trend — The serum β-hcg trend recorded for the scenario being assessed.
  • Progesterone — The progesterone recorded for the scenario being assessed.
  • Ultrasound findings — The ultrasound findings recorded for the scenario being assessed.

Note: Interpret the ectopic pregnancy risk result against the thresholds and context described above.

How to Use

Enter the serum β-hCG trend, progesterone, ultrasound findings for the scenario you are assessing. Calculate ectopic pregnancy risk using serum β-hCG trend, progesterone, and ultrasound findings. Discriminatory β-hCG zone (1,500-3,500 IU/L) with absent intrauterine gestational sac increases ectopic probability. Guides methotrexate eligibility. Use the ectopic pregnancy risk result to inform your calculation.
