What is the estimated gestational age of a patient with a quantitative hCG level of 80,000 mIU/mL?

The estimated gestational age can be assessed through quantitative hCG levels, which rise predictably during early pregnancy. Human chorionic gonadotropin (hCG) levels can provide insights into how far along a pregnancy is, as specific ranges are associated with certain gestational ages.

A quantitative hCG level of 80,000 mIU/mL typically corresponds to a gestational age around 9 to 12 weeks. During this period, hCG levels generally peak and can reach values between 50,000 and over 100,000 mIU/mL. This peak typically occurs around the end of the first trimester, correlating with the rapid increase in the number of trophoblastic cells producing hCG.

For other ranges, lower hCG values align with much earlier gestational ages. For instance, levels of around 1,000 - 5,000 mIU/mL might suggest approximately 4-5 weeks of gestation, and 6,000 to 15,000 mIU/mL might indicate around 5-6 weeks. Hence, the value of 80,000 mIU/mL aligns closely with the later part of the first trimester, confirming the estimated gestational age of 9-12 weeks
