Is it true that higher HCG levels take longer to double??

Postby skye skye » Fri Jul 17, 2015 10:14 am

I had my 1st beta done wednesday and my second today. Just got my results back:

1st beta: 6,720
2nd beta: 10,521

My doctor says that it is close enough to a 50% increase that it's okay...but I'm freaking out it didn't double? I researched a little and found some information that higher levels of HCG (typically levels over 6,000) can take up to 96 hours to double - not the 48 most go by. My doubling time is 74 hours...

I know my numbers did go up, but I'm scared that they didn't double. I have a scan next wednesday...that is sooo long to wait! 8O :doh: What do you ladies think???

At the very beginning HCG takes about 48 hours to double, but as you progress it can take longer - up to 3 1/2 days to fully double by the time you're 6 to 7 weeks in :) If your doctor isn't concerned, I don't think you have reason to be either.

This may also help :)

Morse and coworkers (2012) at University of Pennsylvania School of Medicine recommend that the beta hCG level for a successful intrauterine pregnancy should be expected to increase by at least 35% in two days.

Thanks Frosted!! This is my 3rd pregnancy in the past year - the last 2 were mc's, so I'm kind of paranoid. I didn't get betas done the first two times, so I have nothing to base my numbers off of besides the whole "doubling" rule. I think my number went up by 56% - if I did the math right. I'm only a little over 5wks right now - so I guess it's just a good thing my number is high?

Thanks for the info :D
