The gpal is an umbrella term for four tests, including the number of pregnancies, the number of births, the number of abortions or miscarriages, and the number of surviving children. Gpal is usually found in gynecological examination reports, maternal health handbooks, and in the medical records issued by doctors during obstetrical deliveries and hospitalizations, and it is mainly a conclusion drawn by doctors through the history of the disease, which has nothing to do with ultrasound and cannot be found out during the checkups. In gpal, g stands for the number of pregnancies, p stands for the number of births, a stands for the number of abortions or miscarriages, l stands for the number of surviving children, and there are also spermatogonial antibodies. In general, during pregnancy checkups, especially during early pregnancy tests, doctors will fill in details of a woman’s pregnancy, childbirth and miscarriage, so as to observe the overall physical condition of the woman and provide a basis for further examination and treatment.
