At what beta-hCG level can a gestational sac (GS) typically be detected?

A gestational sac can typically be detected via transvaginal ultrasound at a beta-hCG level of approximately 1,500 mIU/mL. This level indicates that the pregnancy is likely at least a few weeks along, which is when the gestational sac becomes visible.

It's important to understand that beta-hCG levels can vary widely among individuals and pregnancies. However, guidelines suggest that by the time levels reach around 1,500 mIU/mL, the likelihood of visualizing at least a small gestational sac is significantly increased. This knowledge helps healthcare providers in diagnosing early pregnancy and evaluating for conditions such as ectopic pregnancy or abnormal gestation.

Higher levels of beta-hCG may indicate the presence of a gestational sac, but detecting it reliably begins around this threshold.
