An automated Walmart pregnancy testing device has been detected by the US Food and Drug Administration.
The automated device has a 0.4% detection rate of pregnancy for the first trimester and a 0% detection for the second trimester, which means it has not been able to differentiate between pregnancies.
It was created by a company called L2 Technologies, which has been in business since 2009.
The test was supposed to detect pregnancy in the first and second trimesters, but the FDA said that it is unable to do so.
Walmart has not released a statement on the incident.
The test is currently undergoing testing and will be available to Walmart employees starting on Monday, the company said in a statement.
A Walmart spokesperson said the company has tested over 100 million pregnancies and the detection rate was extremely low.
The FDA said in its statement that it did not have sufficient data to determine whether the Walmart pregnancy detection device had any negative impact on the number of deliveries.
It is not yet known how many Walmart workers may be affected by the device.
A spokesperson for the US Consumer Product Safety Commission told the Associated Press that the agency does not know how many people may be exposed.
The FDA did not immediately respond to a request for comment.
