How does beta hCG allow you to know your gestational age?

The production of beta hCG begins shortly after fertilization of the egg and, generally, its levels in the blood gradually increase until the 12th week of pregnancy, at which point they stabilize and decrease again until the end of pregnancy.

How to understand the result of the calculator?

According to the beta hCG value entered, the calculator will indicate the possible weeks of pregnancy, based on the intervals indicated in the previous table.

For example, a woman with a beta hCG value of 3,800 mlU/ml You may receive weeks 5 and 6 as a result, as well as weeks 25 to 40. If the woman is at the beginning of pregnancy, this means that she should be in weeks 5 to 6. However, if she is at a more advanced stage of pregnancy, It is possible that the most correct result is a gestational age of 25 to 40 weeks.
