Placenta Grade 1 at 30 weeks refers to a placental maturity of Grade 1, which is normal and suggests that the placenta is continuing to deliver nutrients to the fetus and is an early stage of placental maturity. Clinically, placental maturity is categorized into four grades: grade zero, grade one, grade two and grade three. Grade zero means that the placenta is not yet mature, mostly seen in the middle of pregnancy. Grade I is when the placenta begins to mature, most often seen in pregnant women between 29 and 36 weeks of gestation. Grade II is when the placenta has basically matured, most often after 36 weeks of pregnancy. Placenta grade 3 is when the placenta has matured and is aging, usually after 38 weeks of gestation.
