IVF beta hCG levels calculator

Beta hCG database, levels chart, scatter plot and doubling time calculator by days after ovulation, IVF embryo transfer and missed period in early pregnancy.

“Normal” doubling time

Beta-hCG LMP (DPO) * Doubling time
< 1200 < 5 weeks (21 dpo) 2-3 days (48-72 hours)
1200-6000 5-6 weeks (21-28 dpo) 3-4 days (72-96 hours)
> 6000 > 6 weeks (28 dpo) more than 4 days (96 hours)

LMP – last menstrual period.
DPO – days past ovulation (post-ovulation).

High levels of hCG

Extremely high levels of hCG may suggest multiple pregnancy (twins, triplets, or more).

Low levels of hCG

A low level of hCG may mean that ovulation occurred later than expected, if the HCG level is rising (doubling) adequately.
