Monitoring

Blood pressure (BP) is measured and urinalysis is routinely performed during each prenatal visit.[31]​ The frequency of visits increases as the pregnancy progresses or if BP is increasing.

At each visit, maternal and fetal evaluation are undertaken, including complete blood count, liver and renal function tests, and quantitative urinary protein testing (spot testing where available, or 24-hour urine collection), as needed.[1]​​​[5]​​[65]

Placental growth factor (PlGF)-based testing should be performed on one occasion.[5][28]

In women under 37 weeks' gestation with hypertension, outpatient management with close supervision is acceptable. Women with severe hypertension (systolic BP ≥160 mmHg and/or diastolic BP ≥110 mmHg), or who are symptomatic, require admission for antihypertensive therapy.[5]
