How Is Preeclampsia Diagnosed? Tests, Criteria & Process
Preeclampsia diagnosis relies on Pelvic and transvaginal ultrasound, FSH, LH, AMH, and estradiol (ovarian reserve), Progesterone Day 21 (confirm ovulation). Learn the full diagnostic pathway, clinical criteria, differential workup, and what to expect at your evaluation.
Updated March 27, 2026
Preeclampsia is diagnosed using Pelvic and transvaginal ultrasound, FSH, LH, AMH, and estradiol (ovarian reserve), Progesterone Day 21 (confirm ovulation) and targeted clinical evaluation. Preeclampsia is a pregnancy complication characterized by hypertension and proteinuria after 20 weeks gestation, potentially progressing to eclampsia (seizures) and multi-organ failure. Delivery is the definitive treatment; low-dose aspirin is preventive in high-risk women.
Clinical Context
The diagnostic process for Preeclampsia begins with Clinical and menstrual history; pelvic ultrasound and hormonal blood tests first-line; laparoscopy if non-invasive workup is inconclusive. Key investigations include Pelvic and transvaginal ultrasound, FSH, LH, AMH, and estradiol (ovarian reserve), Progesterone Day 21 (confirm ovulation), Semen analysis (concentration, motility, morphology). The gold standard is: Laparoscopy for endometriosis; semen analysis for male factor; hormonal panel for anovulatory causes. Clinical guidelines from RCOG / ESHRE / ACOG / NICE define the diagnostic criteria and recommended investigation pathway.
