China's BGI defends COVID-19 test kit after Swedish criticism

China's BGI Genomics said on Wednesday its coronavirus testing kit has "relatively high accuracy", a day after Sweden said about 3,700 people received false positive results due to a fault in the company's product.

BEIJING, Aug 26 (Reuters) - China's BGI Genomics 300676.SZ said on Wednesday its coronavirus testing kit has "relatively high accuracy", a day after Sweden said about 3,700 people received false positive results due to a fault in the company's product.

Sweden health authorities said on Tuesday that the test kit, which has been widely exported to other countries, could not distinguish between very low levels of the virus and a negative result.

BGI said devices sensitive enough to detect a smaller amount of the virus would deliver positive results, while less sensitive products would return negative results.

"The company's test has relatively high accuracy and received positive clinical assessment," it said.

The global surge in demand for coronavirus test kits has allowed BGI to expect its net profit to jump about eight times in the first half of this year.

But the purchase of test kits from BGI, which has grown into one of the world's largest genomics companies over the past two decades, has been controversial in some countries.
