High BP occurring during pregnancy can be divided into four categories: 1) chronic HTN in pregnancy: existing HTN or taking antihypertensive medication before the 20th week of pregnancy, 2) gestational HTN: new HTN diagnosed after the 20th week of pregnancy in the absence of proteinuria, 3) preeclampsia: HTN diagnosed after 20 weeks of pregnancy accompanied by proteinuria (albumin more than 300 mg in 24-h urine or urine albumin/creatinine ratio of 300 mg/g or greater), and 4) preeclampsia superimposed on chronic HTN: preeclampsia is diagnosed in the chronic HTN in pregnancy. Here, ALB is linked to preeclampsia.
