Could you explain why such a high value is being used?

Dear OIA Requests,

Further to my request above, I would like to draw your attention to the PCR handbook:

https://www.gene-quantification.de/real-...

If you look at page 25, you will see at the bottom of the page, the following:

"For Research Use Only. Not for use in diagnostic procedures.”

Should the PCR process be used for testing Covid-19?

Yours sincerely,

Virginia Crawford
