The minimum hCG level required for an ultrasound to detect a pregnancy is typically around 1,500 to 2,000 mIU/ml. This is known as the discriminatory zone, where a transvaginal ultrasound can usually visualize a gestational sac. However, individual cases can vary, so it is essential to follow medical advice for accurate diagnosis and monitoring.
