Evaluation
Repeat B-hCG Levels
| Pregnancy Type | B-hCG Change |
| Normal |
|
| Ectopic |
|
| Miscarriage |
|
- A single hCG level cannot reliably distinguish intrauterine from ectopic pregnancy[5]
- The discriminatory zone (typically 1,500-3,500 mIU/mL depending on institution) is the hCG level above which a gestational sac should be visible on transvaginal ultrasound[6]
