The Department of Health (DH) was notified by Johnson & Johnson (Hong Kong) Limited that the company had initiated a voluntary recall of blood glucose test strip which may provide low readings.

Only one affected lot (lot number 2966727) of LifeScan OneTouch SureStep Test Strips was supplied to Hong Kong.

The affected test strips may provide low test results when the blood glucose level is greater than 22.2mmol/L, a DH spokesman said.

"A total of 2,160 boxes of the lot have been imported to Hong Kong. Among them, 2,116 unsold boxes have already been retrieved from the market. Only 44 boxes have been sold in Hong Kong," the spokesman said.

The DH has not received any report of adverse events arising from the test strip.

Members of the public should stop using the affected product and contact the company at hotline 3128 8101. It will operate daily from 9am to 6pm including the Chinese New Year holidays.

The department will closely monitor the recall.
