Dr. Deng Xuanbi
Hello, during pregnancy, a woman’s amniotic fluid index (AFI) is considered normal when it ranges from 5 to 18 cm. In the third trimester, amniotic fluid volume often increases; therefore, an AFI between 10 and 18 cm is still within the normal range. If the AFI falls below or exceeds this range, prompt medical evaluation and treatment are recommended. We hope this information is helpful to you. Wishing you a happy and healthy life!
