Course Access
Hi Leanne and Crystal,
I could only find 2 articles with the stats for false positives with RAT in general and the articles said 6% and 8% which seems overly high.
This isn’t in regard to people recovering from Covid but I also wonder as we have move into RAT for asymptomatic people in our workplace as a precaution, how high will false positives actually are in general.
Interested also in any other information on false positives.
kind regards

I can’t find a similar recommendation for Victoria but I think this is a good guideline to use.
