Introduction
A serum human chorionic gonadotropin (hCG) level below 10 U/L indicates that you are currently not pregnant. Human chorionic gonadotropin is absorbed by capillaries, enters the systemic circulation, and is then excreted from the body through urine. Therefore, if a person is pregnant, the serum hCG level will be significantly higher and rise rapidly.
Serum human chorionic gonadotropin (hCG) levels below 10 U/L indicate that the individual is currently not pregnant.
Human chorionic gonadotropin is primarily secreted by the placenta. In general, healthy individuals have low serum hCG levels, typically ranging from 0 to 5 U/L. In women who have recently engaged in sexual intercourse, once sperm fertilizes an egg and the resulting embryo implants in the uterus, trophoblastic cells within the placenta begin to secrete hCG. This hormone helps suppress lymphocyte activity, protecting the embryo from attack by the body's immune system and supporting the normal function of the corpus luteum. hCG is absorbed into capillaries, enters systemic circulation, and is eventually excreted in urine. Therefore, during pregnancy, serum hCG levels rise rapidly and significantly. If a woman’s serum hCG level is less than 10 U/L, it indicates she is not pregnant.
Women who are trying to conceive should maintain regular sleep patterns, follow a light diet, monitor bodily changes, and may also visit a hospital for blood tests to confirm whether pregnancy has occurred.
