      They’re pretty good, but not perfect.

      Useful if you’ve been somewhere where someone had covid, or you need to show you tested negative and have no known contact with a covid case.

      If you have been in close contact though, or showing symptoms, you need to get a proper test.

          From what I've heard and read about it… But not as accurate as the drive-up tests, but accurate enough to make a difference in reducing the risk of transmition.

      • Bettyboo on 16/11/2021 - 17:37

        In NSW and Vic if a school child is a close contact they can still go to school take a rapid test daily; until they test negative on a day 6 PCR.

        • RSmith on 16/11/2021 - 18:07

          That's incorrect at least for VIC.

          It depends if the child is partially vaccinated or fully vaccinated at the time of exposure.

    • MasterScythe on 16/11/2021 - 11:07

      I looked into this months ago: from memory…. false negatives are in the decimals of percent chance. And false positives are something like 1% (of people who have a different coronavirus: eg. Are sick anyway).

      So "extra safe" i guess. But thats why a positive result means drivethrough test time.

      • factor on 16/11/2021 - 11:17

        Huh - the info sheet at the TGA says it misses 10% of infections (sensitivity 90.1%). Cheap for a reason.

        • JohnHowardsEyebrows on 16/11/2021 - 11:21

          The infections it misses as those which are shedding less virus, ie less infectious.

            +6

            @JohnHowardsEyebrows: In the real world a good chunk are likely due to improperly administered tests (why these tend to be not much more effective than flipping a coin outside clinical tests).

            Also, it seems to miss more earlier cases than later cases. Actually missing up to 15.4% of positive cases in 0-3 days since symptom onset, but only 6.5% 4-7 days after symptom onset. So it's more useful when you've probably had enough time to seek a PCR test anyway. :\

            As long as you administer it properly I guess it's an added safety net, but only really a net gain if people don't use a negative result as 100% proof and become more reckless as a result.

          Thanks for that, they're less effective than the breath sampling ones. Wouldnt have expected that.

          Thats OK, a 90% chance to catch a hidden infection is still better than 0% if you're about to expose a vulnerable community.

          90% less covid would be a nice chunk…

          Other tests are more senitive.

                  @ozhunter: You should talk to a professional about your life outlook if that's what you guess from that statement, its and extremely unhealthy 'default' to fall back on. Its not healthy to expect people to live 'to the lowest denominator' (be that health, behavior, or ethics), we should always demonstrate a sensible level of additional care, directly proportional to the level of risk.

                  By your logic, the fact that a doctor lets a healthy person outside of a sterile clean-room means they dont care, because they're not being treated as carefully as someone who, say, just got a new heart.

                  Allow me to clarify:

                  Additional care for a specific group does not denote a lack of care for another.

                  Its similar to handrails in bathrooms.

                  Just because they're more often needed for the elderly or disabled, doesnt mean that level of extra care is needed for everyone.

                  Understand?

                  To bring it back; a disease that the healthy can be vaccinated against, and is likely to be mild for them; can mean a death sentence to someone with a compromised immune system.

                  I hope thats cleared it up for you, and I hope you find joy soon.

                      Interesting point.

                      I tend to make a trip into a town once a fortnight, occasionally weekly, for groceries and typical rural supplies. All my export is no contact.

                      So the expectation that i use one before i go into town once a week, isnt too big of an ask.

          That's about what you expect from rapid antigen testing. If you take several test one or more days apart the chances of a false negative (person has covid but test showing negative) returned on all tests becomes:

        It is likely that positive tests soon after recovery represent persisting excretion of viral Novel RNA, and it should be noted that PCR tests cannot distinguish between “live” virus and non-infective RNA.

                      The reason that "people would gravitate to: "eww China"" is because most people do not support slavery. But hey if that's you, at least you're open and honest about it.

                        @1st-Amendment: why it's cheap, doesn't change the saving percentage; so yeah, it can absolutely still be a nice saving.

                        Also, you dont need to support something, to exploit the positives of a bad situation.

                        In fact, unless you control the bad situation directly, thats usually the only way you can ensure some good does come from a bad situation.

                        I dont support cruelty to animals either, but I still enjoy a half work day on Melbourne Cup.

                          At least you're open and honest about your position towards slavery. As long as there is a bargain to be had, why should you care about human rights.

                          I'm interested if this extends to the former American slaves or Nazi death camps. Plenty of bargains to be had there….

                            You seem to be thinking these are mutually exclusive.

                            You should care, because they're people.

                            Absolutely. Im against them also.

                            I have owned some 'era' made products, I agree, the construction quality can be amazing.

                            Does 2nd hand quality products count as 'bargains' though? I guess thats up to you.

                                What suggests im happy about it?

                                I can be happy with a bargain, without being happy about the "why".

                                Ive bought deceased estate before.
                                Am I happy it was cheap? Of course! Am i happy the reason is that this person died alone (no will)? Nope!

                                Also, what suggests 'happy' as opposed to indifference or perhaps anti-with-a-weak-conviction?

                                  Because why is important to most people. Stealing isn't usually considered a "nice bargain" because you got it for free.

                                  Ive bought deceased estate before.

                                  Not even close to being similar. Buying a deceased estate does not support or promote anyone being killed. The family doesn't sell a deceased estate then go find more family members to kill to make more money.

                                  Also, what suggests 'happy'.

            @1st-Amendment: If you mean the prisoners, yes, I think they should better be working (on an 8-hour shift) rather than doing drugs and watching TV all day spending taxpayers' money.

            If you mean otherwise, well, I can only say, don't learn serious news from South Park (which I liked, but it's just an ironic show).

            Also, the chance you get the prison labor stuff is super low, those things are mostly strategic resources acquired by the nation.

        • gadget on 16/11/2021 - 15:13

          According to Costco's own description the country of origin is Australia, so risks leading people to believe it's made in Australia.

          Ozbargainers can make up their own minds as to whether to buy or not.

      • whatgift on 16/11/2021 - 15:00

        Personally I see the country of origin as irrelevant, so stating it so directly suggests a negative connotation, which some people will downvote.

      • gadget on 16/11/2021 - 15:15

        TBH don't care what OB people say (neg away) - as I said below Costco states the country of origin as Australia. I would naturally assume it's made locally.

    • airpoe on 16/11/2021 - 11:30

      According to Costco its origin is Australia. But on govt site its from China.

      Costco needs to correct their website

        The Costco warehouse is in Australia

        The stores get them from the warehouse.

        Ergo, they are from Australia.

      From what I can see on the TGA website, a lot of test kits (even the ones used at the test sites) are coming from China.

    • SimAus007 on 16/11/2021 - 12:57

      And the problem with them being made in China is?

      • BargainMac on 16/11/2021 - 14:42

        Not sure, I guess "China"?? is it?
        Do we have any other option? I guess not. Most OzBargain deal are because as someone said above "Hey! labour is cheaper there, nice savings!"
        :)

        The problem is that it's incorrectly represented by Costco as to where it's made.

          Yeah, im not sure what his point is.

          i agree it looked like a monumentally stupid gamble, but whether by luck or education, it ended up being the right call…

          Im quite happy with the AZ pfizer combo results (germany did it first); and we will soon have novavax hopefully.

          I sort of agree, waiting 8 months in a pandemic is "stupid". But for once, I think ill give them the benefit of the doubt, that we had scientists looking over the data, and deciding, not pure luck.
