Pregnancy urine estriol determination (E3)

Estrogen is mainly produced by the ovary and placenta, and a small amount is from the adrenal gland. After estrogen secretion, it is inactivated and metabolized in the liver, and is excreted by the kidneys through the urine. Estriol is secreted by a placenta in pregnancy, which is mainly secreted by mature follicles and corpus luteum in the ovary. Estriol is important for understanding the function of the placenta and identifying fetal diseases. Urinary E3 increased rapidly during the 29th week of normal pregnancy, and the average E3 excretion in normal term pregnancy was 88.7nmol/24h (24.2mg/24h). Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Found in pre-eclampsia, no brain, hydrocephalus, overdue pregnancy, stillbirth, irregular menstruation, malnutrition, hypothyroidism and so on. Pregnancy urinary estriol excretion is normal, suggesting that the fetus develops normally in the uterus. If the discharge is reduced, it indicates that the fetus is growing retarded, even dangerous or dead. Normal value: Pregnancy E3 (pregnancy 30 weeks): 21-62μmol/24h Pregnancy E3 (35 weeks pregnant): 31-97μmol/24h Pregnancy E3 (pregnancy 4:45-146μmol/24h Above normal: Found in pregnancy, heart disease, cirrhosis, renal function decline and so on. negative: Positive: Tips: You should not stay in urine when you have severe diarrhea. Normal value Urine 30 weeks of pregnancy 21 ~ 62μmol / 24h; 35 weeks of pregnancy 31 ~ 97μmol / 24h; 45 to 146 μmol/24 h at 40 weeks of gestation. Clinical significance Abnormal results: Reduced: seen in aura, cerebral palsy, hydrocephalus, overdue pregnancy, stillbirth, irregular menstruation, malnutrition, hypothyroidism, etc. Pregnancy urinary estriol excretion is normal, suggesting that the fetus develops normally in the uterus. If the discharge is reduced, it indicates that the fetus is growing retarded, even dangerous or dead. Elevation: seen in pregnancy, heart disease, cirrhosis, renal function decline, etc. People who need to be examined: women during pregnancy.
