What does grade 1 mean?

Placenta grade 1 means that the placenta tends to mature. Under normal circumstances, the placenta is divided into 4 grades. Grade 0 means that the placenta is not yet mature. Grade 1 means that the placenta tends to mature, but it is not fully mature. Grade 2 means that the placenta is close to maturity, but it is not fully mature. Grade 3 means that the placenta is mature. Placental grade is determined by ultrasonic echo of chorionic plate, placenta substance and basement membrane. Generally, many doctors are used to using these four grades to indicate the maturity of placenta. However, it cannot be used to completely judge the condition of placenta or fetus. only by referring to other examination indicators can we judge whether placental function is complete.
