The World Health Organization said on Thursday it was looking into whether “observed irregularities” in a Covid-19 PCR swab test made by China’s BGI Biotechnology (Wuhan) Co, Ltd were linked to how it was used in Sweden, APA reports citing HindustanTimes.
The WHO said it had asked the maker for a “root cause analysis”.
China’s BGI Genomics said on Wednesday its diagnostic 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.
The WHO, which has approved the tests for emergency use, said in reply to a Reuters query: “WHO was notified and has activated the complaint procedure for in vitro diagnostics ... to gauge if the observed irregularities were due to the way the test was used.
“Specifically, WHO has contacted the manufacturer and requested a root cause analysis... We are continuing the work with BGI to determine if further action is required,” it said.
