Public Health Agency for Northern Ireland Nid oedd gan y wybodaeth y gofynnwyd amdani.

Dear Public Health Agency for Northern Ireland,

I have a few questions related to using the PCR test to diagnose Covid-19:

1) Can you tell me the distribution of cycle thresholds used to provide a positive PCR test? In other words, what percentage of positive tests came at what cycle threshold value?

2) Also specifically what percentage of the total positives tests were carried out at a CT value between 30-45?

3) Have you undertaken any viral culture to cross reference with cycle threshold values? If so, what are the results? Additionally, if you have any information about the proportion of culturable samples by cycle threshold can you please provide those.

4) Given the WHO advice on 13 January here https://www.who.int/news/item/20-01-2021.... What steps have you taken to implement this advice and were you following this protocol before then?

Yours faithfully,
stephen-ciaran

Thanks for your email below. This isn’t something we would normally do - requests usually come in directly from the requestor. I have extracted below the relevant email addresses - this should allow you to copy and paste these into a new email (in the "To" section) and simply forward your original request on?
