Of the more than 30 home pregnancy kits available in Australia, 14 have been recalled after pregnant women received negative results using them.
The crackdown was prompted after a report of three false negative results using the One Step HCG urine pregnancy test from a family planning clinic, according to News Corp.
After being contacted by the Therapeutic Good Administration to provide information on the kits, nine suppliers chose to withdraw their products from the market instead of undergoing testing.
Of the remaining products, five were found to be ineffective.
'All devices remaining on the market in Australia have been shown to work reliably and accurately,' a statement from the Therapeutic Good Administration said.
