This ultrasound is much more predictive of pregnancy outcomes than hCG levels. Then, you move onto a vaginal ultrasound at five to eight weeks to look for both a heartbeat and a gestational sac to confirm the pregnancy. There are usually three beta hCG tests (assuming the first and second are positive). What's more important than the absolute beta number is if the number increases substantially over time. The higher the percentage of rise in hCG drawn two days following the initial beta, the better the chances for success. But what's more important than the absolute beta number is the rate of increase over time (it should double every 48 hours). In general, a beta hCG level of over 100 is generally considered a good, positive result. The beta hCG will vary based on the type of embryo you transferred (was it fresh? Frozen?) and when the test is performed. What is a normal hCG level after IVF? There is no single hCG level or cut-off that defines a normal pregnancy. Serum β-HCG is proportional to the number and activity of the trophoblastic cells, and research shows that a higher serum β-HCG level is associated with pregnancy outcomes and IVF success. Beta hCG (aka β-hCG ) is a quantitative serum test (done by your fertility clinic) to determine the level of hCG hormone present in your blood. It is called the pregnancy hormone because it is only present during pregnancy and can be detected by at-home pregnancy tests. Human chorionic gonadotropin (hCG) is the first hormonal message from the placenta to the mother. In this article, we’ll review what the data says about various beta levels. The results of this test are predictive of the chances of success for a baby.
