Does anybody know how sensitive the old style Clearblue pregnancy tests are?

I live outside the UK and only have access to these tests which I think are made in Australia. Thanks

They give false negatives about 3% of the time, but their false positives occur less than 0.1%

So, 1000 women pee on the stick and get told they're pregnant, only 1 isn't.

If a 1000 women pee on the stick and get told they're not pregnant, 30 of them ARE!

pee on a stick website suggests that they are 25 mIU/mL. The old style clearblue plus sign tests do have a reputation for false positives, with thin lines. I hope you get a positive result.

Ah OK, interesting, thank you for the info :-)
