A teardown of a digital pregnancy test has created a buzz after revealing it contained a standard paper test, similar to those used by GPs.

The experiment has raised questions about whether the extra cost of digital pregnancy tests is justified.Some say the electronics give women a clearer answer but others point to the e-waste created by digital test kits.The experiment also found the digital test contained a microprocessor more powerful than early home computers.

But the electronics themselves did not play a role in the hormone detection.Digital pregnancy tests that display the words “pregnant” or “not pregnant” on a screen often cost about four times as much as ones that simply provide a single or double line on a paper strip to indicate pregnancy.For the experiment, Foone used a Walmart Equate digital pregnancy test. The inner workings are similar to those in other brands including Procter and Gamble’s Clear Blue and the Boots own-brand digital pregnancy test.Foone was surprised to find the testing element inside was basically a standard paper test.
