When this Co 1st announced the selling the test kits to US market, I was already sceptical about it. I was not comfortable with the spiking prices and avoided this one and the other one, Clearbridge totally, but monitoring the progress just to see if my concern was correct. My earlier view was, every countries are known to be developing test kits, and the threshold to have a test kits somewhat like face mask, easy to make. What so special about this one? Besides, newer and better ones were being developed by others. Look at the face mask prices, look similiar to the chart of this counter. If this test kit is good, why SG was not using it in the 1st place?

Looking at the lists, it appeared to me that the numbers of test kits developed, just like bubble teas in the market, kind of low thresholds to develope.

In bigger countries, airlines has a domestic market, we can' t fly from Changi to Tuas. Without other countries allowing entry, I am not too optimistic about near term of next 12 months.

The way I see, the test kits developed by so many countries, it appeared to be rather easy except the accuracy is the key issue. If everyone can bring up the accuracy over times, the prices of these test kits will be similar to the face masks, drops like a rock when mass production is on.

The Cares Act signed by Trump recently under HR 748 Cares Act was first tabled on 24 Jan 2019, one year ago before the CoVid-19 surfaced in Feb 2020. It' s strange. How this guy, Joe Courtney knew well ahead of time to table such Act? It' s documented in US' Congress.gov website of the time line of thei Act. https://www.congress.gov/bill/116th-congress/house-bill/748?q=%7B%22search%22%3A%5B%22hr748%22%5D%7D& s=1& r=1

Just like the masks, now $18/50 pcs. Back then was $100/50 pcs. Not too long ago, SS was selling at $36/50 pcs, now is also priced at $18 liao. These test kit believed to be not very high tech stuff, that' s why everyone is producing.

Please see Ms Ho Ching' s comment in her FB yesterday on the test kit:
" Hello, everyone! There are tests, and there are tests. While test kits for antibodies may be faster than the swab and PCR approach, they are not meant to test for covid virus itself. All such antibody test kits should NOT be marketed as covid rapid test kits. That is very misleading. The presence of an antibody only tells us whether we have had been infected. It is a lag indicator of infection. And depending on which type of antibody, it tells of the different phases of recovery or infection fighting. And some antibodies may appear a week after infection, while others appear later. Or it may also take longer than 2 weeks to mount a response with enough antibodies to be detected. This can vary from patient to patient. This is like fever - old folks may mount only a very mild fever to an infection, when a younger person may mount a fever more strongly and clearly. So antibody test kits may be marketed as antibody test kits, with info on accuracy, sensitivity and specificity. They should not be marketed as rapid covid-19 test kits. Speed with low accuracy or poor specificity is worse than useless. What is specificity? It means the test picks up the antibody to covid-19 specifically, and not the antibody to other human common cold coronaviruses, to dengue, or to other viruses or bacteria. Otherwise, we may mistake a dengue antibody for a covid antibody for instance. Am exaggerating to make a point, of course, bcos no serious test kit company worth their salt will make such a basic mistake. What is sensitivity? This is the ability of the test to pick up low amounts of antibodies or viruses. For instance, the typical swab and PCR method can take a short or a long time to do - a short time means we multiply the virus bits a few cycles in a RT-PCR and thus have X amount of virus bits that we may not detect, and so this may be useless as a mainstream test kit a long time means we go through many more cycles to generate many more bits of the virus, and thus we can pick up the virus easier, but if we do this for too long, we lower our throughput capacity. So a test may pick up say 100 viral bits vs another which needs 1000 viral bits, while a 3rd needs just 20 viral bits. And each will require different time to do so, measured in hours under the RT-PCR approach. So this is a case of speed vs sensitivity. This kind of trade off often happens for biological type testing. There are alternative technologies which may be faster, but none are available in commercial quantiites yet - they are still being developed, or are being validated. Finally, the accuracy. This means when we have a reading of Y, we know that the real number could range from Y-Z to Y+Z. To complicate matters, sometimes we have Y-Z1 to Y+Z2. Hee! But let&rsquo s keep to a single Z for simplicity. If Z is a small percentage of Y, we know we can rely on the Y to make a decision. But if Z is bigger than Y, then we pretty much can ignore Y of a certain value. Take the ATP machine - we use this as a first line check of the amount of living microbial organisms say on a door knob. Suppose the accuracy Z is 250, and the machine gives a Y reading of 22. That doesn&rsquo t mean that we are really at 22. It means the true number can be anywhere from 0 to 250. So we should then use the 250 mark as the pass/fail, rather than try to aim to be 0 or 50, etc. The machine just doesn&rsquo t give us that kind of accuracy to make these low numbers meaningful. So media reports on all test kits should ask for their test data and share those test data as a way to educate our people fully, and not get carried away by the focus on speed as if that is the be all and end all of test kits. Or ask for their user base. P.s. I don&rsquo t have the info on the Biolidics off the top of my head, and have no specific information on their test kit performance. But it would be good if Biolidics or any other test kit producers share these information with the media. It is also useful for mainstream media to go get medical or research specialists to help them interpret test kit specs, or go get a tutorial quickly. Under today&rsquo s emergency situation, many health authorities may give provisional status without requiring the full jing-bang of validation and trials that they would normally require. So waving the names of this or that authority is not the way to go. And my apologies to both Biolidics and Straits Times for using their story to hang this PSA peg to alert folks on how we should look at news on this or that superduper 2 minute or 10 minute test kit. Thank you, all, for this opportunity to share some thots and observations. P.p.s. A recent NYT article just reported that of the 14 antibody tests, only 3 gave consistently reliable results. The rest didn&rsquo t perform as advertised. Layman translation - the rest were junk. Even the best 3 had flaws. Only one didn&rsquo t have false positives. Why does false positives happen? One reason has to do with specificity as discussed earlier. If a test cannot be very very specific to covid-19, and recognises something else as covid-19 antibody, we will end up as a false positive. That is a very clear no-no. Others may have very high false positives - which means they are junk tests. More on other points in the NYT article later."
