A move away from PCR testing in the community could free up excess capacity in hospitals which, in the coming weeks, are going to need all the help they can get, argued McNally.

Small hospital labs can easily be overwhelmed by COVID testing demand and cases in hospital look very likely to rise in the coming weeks. Well, some of the first evidence from the UK emerged on Friday showing little difference in the rates of hospitalisation between people infected with Omicron and those infected with Delta.

Good news for those worried that Omicron might be more severe, but not for those suggesting that it might be milder. That small difference could mean a huge increase in the number of people at risk of hospitalisation and death from Omicron, especially if growth continues as it has been.

LFTs instead measure whether viral proteins called antigens are present in a sample. They are only positive when a sizeable amount of virus is present. They therefore give a very good indication as to whether someone is currently infectious.

This difference between detecting the presence of the virus and whether someone is likely to be infectious is critical for deciding which test to use in any given situation. For instance, the recommendation to use LFTs twice weekly or daily for some professions , regardless of feeling ill, makes absolute sense when trying to stop people who may have COVID — but no symptoms — from inadvertently spreading the virus. On the other hand, if the intention is to confirm that someone definitely has COVID — for instance if they have cold-like symptoms that could potentially be caused by other bugs — then conducting a PCR test makes sense.

This difference can be further understood if you compare the tests performance over the course of a COVID infection.

As a PCR test is about 1, times more sensitive than an LFT, it can detect COVID one or two days prior to the infectious period, and then for quite a long period afterwards as the body destroys the last elements of infection. One reason for the widespread delay in delivering results likely has to do with staffing challenges , experts said.

There needs to a broad strategic plan to monitor and ensure access to all types of testing and quick turnaround times. Long delays can also make a test less useful if an individual has the virus and doesn’t know she is infected. That’s where the inequality could be further exacerbated by this,” Columbia University’s Chan said. Omicron variant sparks new safety measures. Please enter email address to continue.
