An expired pregnancy test is not very accurate - but can it give a false positive reading?

Certainly .. it can give a false negative reading, too. If past the recommended date for use, it should be discarded and a new kit bought. There is a very good reason why those expiration dates are put on items ... their shelf life is limited as the chemicals used for the measurement process do not last forever.
