More than 58,000 pregnancy tests were recalled after some women got false positive results / ShutterstockOne brand of pregnancy tests (not the one pictured) told some women they were pregnant when they really weren’t.
  • More than 58,000 at-home pregnancy tests were recalled because a “small number” of women got a false positive result.
  • The tests were distributed in the UK.
  • Under normal circumstances, false positives are very unlikely.

Thousands of at-home pregnancy tests have been recalled after some women taking them got false positive results, People reported on Thursday.

The Clear & Simple brand digital pregnancy tests were manufactured by Guangzhou Wondfo Biotech and sold in the UK, according to a statement from the UK’s Medicines and Healthcare Products Regulatory Agency.

The manufacturer estimated that more than 58,000 faulty tests were distributed, and a “small number” of women who took them were incorrectly told they were pregnant, the statement added.

All of the faulty tests have the same lot number (DM10220170710E) printed on the box. The statement said that anyone who purchased an affected test should return and seek another method of pregnancy testing.

False positive pregnancy tests are really uncommon

At-home pregnancy tests work by detecting the hormone human chorionic gonadotropin (HCG) in your urine. It’s only released when you’re pregnant.

As long as there’s nothing faulty in your pregnancy test, it’s rare to get a false positive result.

In very uncommon cases, a miscarriage, some cancers, or certain medications may create a false positive, Dr. Talitha L. Bruney, medical director of OB-GYN at the Comprehensive Family Care Center, Montefiore Health System, previously explained to INSIDER. But most of the time, a positive result means you’re pregnant.

“It’s very unlikely to have a false positive,” Bruney said. “But all positive tests should be confirmed at a doctor’s office.”

In other words, if you do take a positive pregnancy test, see a doctor. He or she can confirm your at-home result and determine how far along you are, according to the American College of Obstetricians and Gynecologists.

False negatives are actually far more common than false positives, Bruney added, largely because many women test too early. Planned Parenthood explains that pregnancy tests are most accurate when you take them after a missed period. Take a test before then and you’ll get less reliable results.
