Yes, somewhat off-topic (though pregnancy is very much on-topic much of the time). A reminder that all tests are fallible. Discordant test results need to be cross-checked using different techniques, different labs. Not just ignored or dismissed.
Faulty batch of 58,000 Clear & Simple pregnancy tests recalled
UK-sold Clear & Simple digital pregnancy tests made in July 2017 have returned false positives
Consumers have been urged to check that they do not have one of a batch of faulty pregnancy tests, amid fears that they could incorrectly show a positive result.
The makers of Clear & Simple digital pregnancy tests said there had been a “small number” of false positives, all related to a batch of the kits made in July 2017.
More than 58,000 affected kits were distributed in the UK, according to the manufacturer, Guangzhou Wondfo Biotech.
The Medicines and Healthcare products Regulatory Agency (MHRA), which oversees medical devices and drugs in the UK, said that it had been alerted to the problem in early September.
The faulty kits all carry the same lot number, DM10220170710E, and have an expiry date of 9 January 2020. They have been available in the UK since last November.
