What HCG level does clearblue detect?

[dippyegg32]

Hi all, please could someone help? I've got strong positives on FRER, today is either 9/10dpo but a weaker cb. I know FRER detects HCG as low as 6 but what is the cb detection rate please? I'm worried by how different they are. Thanks.

Depends on the type of clear blue test I think. What one was this?

If it was an ultra early test with a colour change tip then then it's 10mIU/ml and a CB digital is 25mIU/ml.

This is the box I have with 2 leaflets inside where the above info came from.

The Clearblue ultra early tests (which I think you've got there) are 10mIU/ml.

Congratulations!

Yes sorry it's the ultra early, thank you. Still quite concerned they're so different but will test again in a few days.

I understand exactly why you're anxious (I was exactly the same in the early days with my pregnancy with DD and really agonised over progression) but I think all you can do is keep reminding yourself that pregnancy tests are not designed to be used in that way and that today, right now, you're pregnant.

Wishing you the very best of luck!

OP I think FRER are 6mIU compared to the CB’s 10, so understandable that it’s lighter. Congrats!
