ONS Admits Ignoring Manufacturer Instructions in PCR Testing

The Office for National Statistics has admitted that in its Covid infection survey it has been reporting PCR tests as positive when only a single coronavirus gene is detected, despite this being contrary to the instructions of the manufacturer that two or more target genes must be found before a positive result can be declared.

The kit used by the Glasgow and Milton Keynes lighthouse laboratories is the ThermoFisher TaqPath RT-PCR which tests for the presence of three target genes from SARS-COV-2. Despite Corman et al originating the use of PCR testing for SARS-CoV-2 genes there is no agreed international standard for SARS-COV-2 testing. Instead, the World Health Organisation (WHO) leaves it up to the manufacturer to determine what genes to use and instructs end users to adhere to the manufacturer instructions for use.

Is this one reason the ONS consistently reports higher Covid infections than the ZOE Covid Symptom Study, which tracks symptomatic Covid? In its latest report published today, the ONS estimates 192,300 people had Covid in the UK in the week ending March 13th, whereas ZOE estimates 109,400 people had symptomatic Covid in the middle of that week – almost half the number.
