HCG bloods are over 4000 but CB digital says 2-3 - anyone else?

[OneHourParking]

I had my HCG bloods done and they were over 4000. On the same day I did a CB digital weeks indicator, and only got a 2-3.

CB says the threshold for getting a 3+ is HCG of 2753. I should easily be getting a 3+ using my blood reading.

Can anyone explain why there is a mismatch please and what it might mean? Thank you.

I wouldn't go off the CB at all and instead refer to your blood results as those are actually accurate.
CB aren't accurate and not supposed to measure hcg.
Mine were never correct. I didn't get a 3+until 6 +weeks , then my hcg was so high on cheap tests I had the hook effect and panicked.
My advice is once you've had your positive stop testing as they arent designed to monitor pregnancy. . I almost drove myself mental taking tests . Once you've had a positive, your pregnant. Leave the testing alone
Best of luck

my first beta was 9000+ (twins tho) and I was getting 2-3w on digital. It hit 3w after my readings were over 20000 tbh. Don’t look too much into them

Honestly, those tests are the worst. They sent me round the bend with worry as I couldn’t get a 3+ and if you look there’s lots of other threads saying similar. Everything was fine for me but I didn’t have a 3+ until quite a lot later than they say. The fact that you’ve had the blood test is great, try and forget about the CB 🙂
