What is beta hCG (beta-hCG)?
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. 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.
How long does it take for beta hCG levels to increase?
By 6 to 7 weeks beta hCG levels may take as long as 3 1/2 days to double. hCG normally reaches a peak level at about 8 to 10 weeks and then declines for the remainder of the pregnancy. The beta hCG level for a successful intrauterine pregnancy should be expected to increase by at least 35% in two days [ Morse and coworkers (2012)].
How to calculate doubling time of two beta hCG samples?
Beta hCG doubling calculator can be used to calculate the doubling time of two beta hCG samples by entering the date of the blood test and the corresponding beta hCG value for that day Some Facts About hCG hCG levels are higher when carrying a female baby than a male baby.
When should beta hCG be taken after embryo transfer?
Another study in 2017 looked at mean hCG levels on Day 12 after an embryo transfer. Researchers found that beta hCG has a good predictive value for assessing the clinical pregnancy outcomes. Data from study of 123 IVF participants. Beta hCG levels were taken 12 days after an embryo transfer. What does a high beta hCG mean?
