PCR test relibility ?

Anyone with recent experience have advice.
Wife & I plant to holiday in Funchal, and will need
a test. Providers seem to guarantee results within
24-48 hours of receiving the sample. All seems a
bit iffy to me as the test cannot be more than 72 hours
before departure. Any advice gladly received.

Are you sure that you cannot be tested on arrival ?

I recently travelled with TUI. The test that was taken before we traveled (obtained through TUI and you can't use the NHS ones) was a simple lateral flow test where you posted the results on line along with a photo of the result (it had a unique serial number). You get an acknowledgement and a reference to use.

Coming back at day two, it was a PCR test that you sent off to be checked. Your details are linked to your passport and you don't need to do anything with your results (unless positive of course).

I've used the Boots in-store testing service three times this year and each time my result arrived within 24hours. It is a PCR test and the attendant/sample collector did mention the 24-48hr timescale.
I normally schedule my test to be at 48hrs to departure so expect to get the result the day before departure or if delayed (fingers crossed) on departure day itself. So far, no problems with my timing.

So basically they're making you pay for something you can otherwise get for free. Disgusting behaviour, but no entirely unexpected

Is this a test you do yourself at home, or is it a test centre one? I ask as we're booked to go to Rhodes in October (with tui). All been double jabbed so no worries over quarantining but still a bit confused to what tests to get.

Is there any check that the test has actually been done? The ‘free issue’ NHS tests show a negative valid test result if you simply drip the fluid into the test strip without a swab going anywhere near you. I can’t see the point of any unsupervised test being used for any pseudo-legal purpose.

It looks like PCR test are here for a long time as governments say they are looking for evidence of new variants.

I'd assumed that the CT (Control) line that appears on the strip for both positive and negative tests is for some universal bacteria found in the nose and throat and confirms that the swab contained a sample. Are you saying that the fluid generates the CT line on its own?

Just to be clear, it's a government rule that will not allow you to use the NHS lateral flow tests and not a TUI Scam (they have discounted them). You are free to take them on your own without any supervision.

By now, you should know that the whole testing thing is a mess and you just have to play the game. On entry into Kos, we had to take a (free) test at the airport before they would let anyone in. There is nothing at the UK airports. Our hotel had provided a booth and a doctor for EU visitors to take their tests before they returned home. We just used the ones we took with us.

Another farce was the Passenger Locator Form that we filled in on-line before we came home. Got to the airport to find that it had changed that day and was no longer valid and we needed to fill out a new one (the new one had our vaccination status on it). Not an easy task when you are queuing with your baggage...

Ultimately though, the tests are still a relatively simple process, so don't let it spoil your holiday.

It should do. The control line in a lateral-flow test is confirmation that the "flow" from the sample loading pad to the antibody binding area has occurred. It is purely a technical control and tells you nothing about whether the sampling was done correctly.

Arrived home yesterday from a five day break in Bavaria. To summarise:

Pre register with the German Federal Government prior to departure.
Book PCR tests to be done 72 hours prior to return (results must be available prior to flight, they were checked at boarding gate).
Passenger Locator forms to be completed within 48 hours of return (checked at boarding gate and Immigration on arrival).
Book PCR tests to be done 2 days after arrival.

2 PCR tests in Germany: 178 Euros
2 PCR tests in U.K.: £ 114

Nice break but plenty of admin and additional cost. PCR Reliability seems to be taken as sacrosanct by the authorities here and in Germany.

Or they have bought billions between them all and need to shift them? Looking for new variants are important… unfortunately the U.K. is only sequencing about 6% of positive cases so despite the obscene costs, they’re not being used as intended.

Just more political guff. We need to test PCR samples from around the world and the rest of the world was slow to get this going. It has improved in 2021. But although there may be some value in testing people arriving from some remote third world country, it is illogical to test people coming from, say, Germany which is testing hundreds of thousands on a daily basis and will pick up any variants far earlier and more reliably than we will from some tourist.

IMHO the politicians have a need to 'do something' whether the something works, is logical or effective.

So, how big does the sample size need to be? Are you looking for a representative sample or the one in a million. To find the one in a million do you actually have to look at everything or can you target your search on the most likely, thereby saving time and money. Which comes back to the question, what percentage would that targeted search be?

Just got back from a 5 day break in Spain.

Printed off my NHS vaccine status from the app, just to be belt and braces in case there was an issue with my phone. . Did test 48 hours before returning from Spain as instructed.

Not one check at either end. Not even asked to scan my QR code at the airport.
