The results of the serum HCG test will normally be available in about 2 hours, but the exact time of the results depends on the equipment and workflow of the hospital laboratory. HCG, known as serum human chorionic gonadotropin, is a glycoprotein hormone released by gestational trophoblast cells and is mainly used to diagnose pregnancy-related disorders such as normal early pregnancy, ectopic pregnancy, gravida or germ cell tumors. Currently, the main clinical test for HCG is the colloidal gold method, which is highly sensitive and easy and rapid to detect. Medical institutions of general size are equipped to test for HCG, but the time to issue the report varies from hospital to hospital due to different testing equipment, different test strips or reagents used, and the limitations of the testing level of the testing department. Under normal circumstances, the higher the level of medical institutions, the faster the report is issued. In addition, HCG is an important basis for clinical diagnosis, especially for women with unexplained abdominal pain, vaginal bleeding, blood accumulation in the abdominal cavity or even shock, and can quickly determine whether the above symptoms are related to pregnancy within a short period of time, which can buy precious time for clear diagnosis and rescue of patients’ lives.
