PCR testing – how many cycles are used in Australia?

We know that anything over 25 cycles is a pile of crap. It doesn’t have any diagnostic validity whatsoever (even assuming that PCR test are not measuring something other than SARS-Cov2).


So how many cycles in Australia? This question has come up quite a bit.

Page 4 of this government document states that “Each amplification reaction is known as a cycle, and usually 35-45 cycles are undertaken.”

Doherty Institute recommends 38 or more.

    Australia and New Zealand are using the same PCR-CT as most other countries. Why are their respective confirmed cases per 100000 so low in comparison to the other countries?

    I can only speak for Australia Wayne but our low numbers are nothing to do with the PCR test. We are an island nation and simply shut our borders during the worst of the pandemic. We have kept incoming traffic limited since then. We also test incomers, quarantine, track and trace and even shut our internal state borders when there are local breakouts. In other words we stop the spread and so have had relatively few cases by comparison.
