Warning on faulty pregnancy tests

8th June 2007

A manufacturer has revealed that a batch of pregnancy tests used in UK hospitals were faulty.

The disclosure may mean that tens of thousands of women may have to re-take their pregnancy tests after it emerged that part of a batch of 83,000 kits sent to hospitals and used between March and June this year was not working properly.

The manufacturers of the Clearview HCG tests say the faulty items could wrongly indicate that a woman was not pregnant. It is believed that 44 of the tests were at the centre of the problem.

The faulty batch was made by US firm Inverness Medical Innovations and distributed in the UK by Unipath. The company has contacted 50 hospitals in the UK that use the product to warn them of the possible problem showing a “false negative? result.

Tests on sale at pharmacies are not affected by the fault.

The Royal College of Obstetricians and Gynaecologists said that women who are worried that they may have received a faulty test should contact their GP or hospital or buy a second test from a pharmacist to double-check.

Unipath said that the fault went undetected because such a tiny proportion of the 83,000 in the batch were affected. A spokeswoman said the company was now confident that the problem had been correctly diagnosed and was being rectified by changes to the manufacturing process.

“We would like to apologise for any inconvenience this recall may have caused to our customers or their patients,? she added.
