Being a biomedical researcher, I'm proud of the scientific community for working so hard to compat SARS-CoV-2. First diagnostic tests were developed and distributed within weeks of the pandemic, antibodies against SARS-CoV-2 have already been established and over 80 scientific institutions are currently working on a vaccine (I made a video about COVID-19 research a while ago). All these progresses really might have saved numerous lives!

Do you test for COVID-19 or SARS-COV-2? I'm confused because from what I understand from reading the literature COVID-19 is a condition with effects like pneumonia and ARDS. SARS-COV-2 is the actual virus causing the disease much like HIV causes AIDS. Which I'm guessing is why there are people infected with SARS-COV-2 who don't show the symptoms of COVID-19 just like how there are perfectly healthy looking people with HIV. Is any of this right or am I off?

I live by a saying: "Something good comes from something adverse." "The adverse is there to smack you upside the head to wake you up." My grandmother's family came down with the 1918 Flu, her parents, two brothers and two sisters; she did not. The two year old sister died but the rest of the family recovered. So that means out of a family of seven: 5 members with symptoms survived, one member did not and one didn't come down with it (or at least didn't show symptoms). It's amazing how far we have come since the early 1900s in understanding what causes these outbreaks and how to put them under control, this was a very informative episode I truly enjoyed it. By the way I do not come down with Colds or the Flu, but I'm not assuming I have nothing to worry with Covid-19. Sofar I've been fine and I definately take precautions: keep my distance, wash my hands and wear a mask and remind myself not to pick my nose.

[@JustAnotherBuckyLover]

​@@2dashville So I read that article and I have a few thoughts - apologies in advance for the wall of text, but hopefully, some of it will be a little more reassuring that yes, doctors and researchers are looking at these things. First off - doctors ARE talking about these things. The PRESS may not be, but that doesn't mean doctors and scientists aren't. Secondly - Although it feels like an age, this has only been going on a very short time and they're trying their best to find the best way to manage things - but without research to demonstrate accurately the most effective treatment? They can only go based on what is being seen and what they know from past experience. The death rate in those sick enough to need ventilating is bad - but then they're already crazy sick if they need ventilating, you know? While it's slightly different, my dad has been hospitalised half a dozen times in the year prior to this pandemic in respiratory failure, mostly comatose, barely responsive to pain, not aware of who he was or where he was, nor what was going on - and we'd been told more than once that he may not make it. He STILL didn't end up on full-blown invasive ventilation. His oxygen levels were down in the 40s and 50s. That gives you an idea of how sick you can be and NOT be on a ventilator. Thirdly - the medications mentioned for treating altitude sickness? One of those is a steroid - which would damp down the immune response, and we already know that some severe cases are due to the immune system producing an overwhelming response that causes massive tissue damage - so yes, using a drug that damps down the immune response may well end up helping those people. On top of that, the other drug simply allows you to get more oxygen into your system, so of course, that may well help some too. Fourthly, the problems with clots, organ failure, sepsis definitely aren't unknown or not talked about. They're just not discussed in most of the press. But absolutely scientists and medics are aware of these issues. Honestly, as a microbiologist, and having seen the amount of BS and nonsense being reported in the media - not just about this, but with all science reporting in general, I'm much happier if the scientific details are left to scientists to report, not news organisations. If this doctor genuinely believes he's onto something, then absolutely, he should be talking about it - but to other doctors and scientists. There could be other factors that are why patients in NYC are not doing as well as in some other areas, but it's going to take some time to unravel all of that. And sadly, there's always going to be people who assume they know the fix regardless of evidence or a lack thereof, (such as the doctor using the residents of an old people's nursing home in Texas (some of whom have dementia) as guinea pigs for hydroxychloroquine and is determined that he will be the "maverick doctor who went against the tide" to prove it's a miracle drug - and yet has made it so that any results he would get are utterly useless statistically). Research has to be done a certain way to be able to put any context and meaning on results - and sometimes that takes time. Until then, the doctors are all supporting people through the disease as best they can, much of the time.

[@2dashville]

Just Another Bucky Lover thanks for replying. I believe it mentions later in the article (not the video) that the steroid should be avoided for covd cases. I'll have to re read it again. I was hesitant to put it out there for the same reasons the original poster of the video was but I'm glad to hear that they are looking into it and in no way want some rogue doctor experimenting on seniors of which I'm one and for the reasons you stated. It's just I never hear about any other viable alternatives being tested other than the malaria drugs and would have hated if this one was late getting in the game. Someone making a connection between low oxygen levels of people with high altitude sickness and covd seemed like an aha moment and in my, I guess you would call zeal, I threw it out there like a message in a bottle in hopes someone smarter than I would read it and you did. Again, thank you for sharing your insight.

Thank you for a video explaining the basics of testing for SARS-CoV-2. You got nearly everything right, except one thing: doctors are not the personnel who perform the tests (and neither are nurses). That would be Medical Laboratory Scientists. I have been an MLS for 10 years. It would be amazing if you could do an episode highlighting the laboratory's role in the diagnosis and treatment management of COVID-19 patients. 70% of all objective data in a medical chart is from laboratory results, and without us, your doctor is just guessing!! Not only do we test for the presence of SARS-Cov-2 and it's corresponding antibody, but we also do a lot more testing to support the treatment of patients who are critically ill with COVID-19. These tests include blood gas analysis, procalcitonin, lactate dehydrogenase, complete blood count, D-dimer, and liver enzymes. For anyone whose interest has been piqued by the science behind the diagnosis, I would strongly, strongly encourage you to look into a Medical Laboratory Science program near you (and some programs available online as well). MLSs are allied health professionals who hold at least a bachelors degree and are nationally board certified by the American Society for Clinical Pathology and work behind the scenes in each and every hospital, providing the actionable data your doctor uses to diagnose and treat disease. My MLS degree means that I can find you a safe, compatible unit of blood; I can look at a blood smear and see a new leukemia; I use sophisticated chemistry instrumentation to tell your doctor you are suffering from liver failure, diabetic ketoacidosis, or an electrolyte imbalance; or look at colonies of bacteria growing on agar and know what kind of bacteria is causing your infection and what the best antibiotic is to treat it. I may never see the patient but ALL of them are my patients. There is a HUGE shortage of MLS personnel all over the US and it is a rapidly growing field. Every day has something new and interesting. A career in Medical Laboratory Science is secure and rewarding.

My suggestion is just to isolate all those who tested positive for COVID-19. I think it really is common sense, but politics seems to always exaggerate. Like AIDS, for example. Although the virus is sexually transmitted, just isolate yourself from someone who's been infected. It really depends on who you talk to because different schools of thought will give you different answers of the same truth. Like, epidemiology and virology are two different subjects--two different answers--of the same truth about the nature of viruses. I know its transmission is respiratory, so it's different from AIDS, but I feel that it's more important to know who's infected so that the government knows who to quarantine, even those who are asymptomatic. I really love this channel. Unlike news channels like CNN, there's so much political bias, and it feels refreshing to get information from channels that just talk about scientific facts.

Could we get more information about the reported high rate of false negatives for the tests they have been using up to now?

[@r3vmixman]

I couldn't get tested so I hugged my rich friend. I find out our results this Friday.

Can you make A video on plasma therapy?

[@annie7395]

Can you clarify distinction between immunoassays used for direct virus detection and for detection of seroconverted patients? Would these both be considered 'serologic' tests? There already seems to be some confusion over the uses of different diagnostics when the most common ones out there fall strictly into swab/rt-pcr and blood/immunoassay

[@annie7395]

Also, why could virus be looked for systemically/in the blood? Wouldn't a dipstick, should it be made available, rely on respiratory secretion sample?

Enzyme Linked Immuno Sorbent Assay one of the most tedious things I've ever done in lab school D:

Get ready for a flood of commenters coming in here wondering why, after watching this video, they still dont know how to get their own test within an hour lol

I'm currently scrolling the comments, looking for anything from the 100 "thumbs down" individuals. I just want some understanding of WHY? WHAT do they find OBJECTIONABLE about this video??🤯🤯🤯

[@colaphoenix6849]

in norway my country the scientists says they have found a new test using nano particles and that the entire country of 5.3 million people can be tested within a month. starting with 150 thousand people a week and probably increasing as time passes and the manufacturing of the test becomes more streamlined. (this happened and was annoucned like yesterday btw)

The title of this one was unusually click-bait-y, but the info it does give is useful and accurate, otherwise.

We only have one case in my county. Sure, it's likely due to no testing, but that just means it isn't here! 🤷🏻‍♀️ /s

@Bart LeFart these people are completely delusoinal. Probably one of the biggest metropolitan areas in the US is hardest hit by the outbreak but hurr durr it's those dumb people in the sticks.

@scishow, Can you guys do an update to this with some of these new 5-minute tests I've heard about, like BinaxNOW.

[@jullyanyewerton7900]

I'm on the 26th day of symptoms and I took the blood test today. It took 20 min to get the results. I got negative but I dont buy that... I'm still coughing a lot, feeling fatigue/tired and having trouble breathing. I've had the stomach pain, like there were needles inside my belly and even a kidney ache for a short time. I've had muscle pain and lost my sense of smell. I had flashes of fever and lots of headache, like there was a cork being pressed against my head. Never felt sick with such symptoms before in my life. I drove (to take the test) and had trouble to breath for a while because of the effort i made. If it's the same test that Trump is testing the reporters to get into the white house, it has a 40% of probability to spot a false negative. That being said, it's just upsetting being more confused than before :(

cant wait for a covid blood test at my hospital 🙌🏻 i get a swab shoved up my nose every other week before chemo. at least know im not infected atm

So to use LAMP we make it super replicate to see it better. Seems dangerous.

[@Arman-lp5mm]

When polymerizing the virus, how does the pcr not multiply your own DNA or that of the bacteria from the sample?

[@bneskylights1152]

With the antibody test for previous infection, wouldn't it show up if you had any type of coronavirus? Not specifically COVID-19

[@JapaneseChefHELLYEAH]

No, antibodies are very very specific so it could bind to SARS but not covid-2

Doctors don't perform testing Doctors don't perform testing Doctors don't perform testing Doctors don't perform testing Lab personnel or nurses do the test. How many doctors do you know that do urine pregnancies or flu swabs.

[@DoctorJammer]

True... and medical doctors often know very little of how the virus actually works and what we should do to prevent spread. It is the virologists, epidemiologists, and molecular biologists that know what is best to treat and prevent infections.

[@Sorkabeth]

Given the percentage of my health care providers who are now PAs or fancy types of nurses, I'm starting to wonder if doctors still exist 🙃

[@thomasstecyk792]

Trying to manufacture three-hundred and fifty million tests. We started behind the curve in the beginning. Then we had bad test kits from China. Cold and flu symptoms mimic COVID-19 symptoms. You get tested today get a negative. Then a month later you still have symptoms You get another test because you have more symptoms. Then you get a positive. The manufacturing companies while are moving faster are not keeping up with demand. This is why we are still testing the patients with the worst symptoms. This is only part of the problem. The rest is what he said.

[@stephanieakright3030]

Hey! I help make antibodies! (not currently Covid, yet..) Check out what Hybridoma's are. It's super interesting how we can use cancer cells to make antibodies for tests! Keep up the great videos scishow!
