What does the book symbol mean on a boots digital pregnancy test?

Answer 1

An error has occurred (with the holder that you place the tester stick in).

Mine did this too, I think it's because I didn't insert it into the holder properly. Make it's firmly place in before doing the test or that'll be another £5 gone!

Answer 2

The book symbol on a Boots digital pregnancy test typically indicates that the test is ready to be used. It is a readiness indicator to let you know that the test is prepared to receive a urine sample for accurate results.
