Looking For Gloves on the Ground [OTG]?

The Covid-19 Antigen Test

To set up a Covid-19 Testing Program, one must first understand the difference between a serologist and an antigen test. The antigen test detects a certain virus protein that appears right after being infected, between zero and five days. After five days, the test loses a lot of accuracy as it's going to give you a bunch of false results, false positives, and false negatives. So the purpose of the antigen test is really to detect if you have been infected with covid-19 recently.

The Covid-19 Antibody Test

The serological test detects the antibodies that will appear 10 to 14 days after being infected. When covid-19 antibodies are detected, it indicates that a specific person has been infected for 10 to 14 days. That is a lot of time to infect other people. So it's a bit of a catch 22.

Covid-19 Test for Virus Infections

If you want to put in place a testing program and use the best test to detect infected people, employees for example. Then one would use the antigen test, ideally twice a week or at least once every week.

Testing For Vaccine Effectiveness

The serological test will be used a lot more for pharmacovigilance, which is after people got their vaccine. Test on a monthly basis to see if they still have antibodies – to see if they are still protected against the covid-19.

Knowing the Purpose for Testing

The point being, there is a different purpose for each type of test. To implement an effective Covid-19 test program one needs to understand them both and to be clear on what the overall program requirements are.

For example, if it's for a government they will likely distribute it to their population, like Ontario. There the government just purchased three thousand antigen tests and they're making them available for free to hospitals or organizations.

If it's for companies, there will need to test protocol. They might need help as well in addressing, "What do you do? How do you test? How do you record? What do you do if someone is positive?" You need to have a protocol in place and there is a lot that may not be obvious. If you or your company need help as part of our service we can assist in discussing what would be most appropriate.'

The Antibody Test

With the antibody test one looks for 2 types of antibodies, IGM and ICG. IGM is very active within the first day of infection. So if you're have IGM, we know that you have a current ongoing infection.

The presence of ICG antibodies indicates that you have essentially a very strong immunity to the corona virus. This usually appears about two weeks after you were infected. This signals that your body is fighting back with a stronger form of an antibody.

The Covid-19 Antigen Test

With the antigen test, using a swab, one is looking for proteins created by the coronavirus. However this antigen, is very similar to many different types of other virus proteins. So there's a lot of false positives that tend to happen with this type of Covid-19 test. On the other hand, testing for antibodies the detection is very specific, very sensitive and more accurate. So that's the real distinction between the two types of tests.

Stop chasing ghosts. Gloves on the ground, that is landed in a warehouse here in North America, are in such demand that before you can confirm it exists they tend to evaporate. There is a way around this, but first lets be realistic of what we can expect in terms of market price by looking at the categories of gloves on the ground that are available.

Nitro Blends Gloves on the Ground :

Just running through the list as of this week we have a lot of blends, a lot of nitro, vinyl blends, and they're all in the high 12s and up to the high 13s. That's the cheapest you're going to find with any nitro in it, whether it's medical or non-medical.


And then we have some nitrile gloves on the ground that are medical or non medical, and they're all in the 13s and 14s and 15s.


And then you have the chemos in the 14s, 15s, 16s and 17s. We have a lot of lots on the ground and they are all odd size lots like 17000 here, 25000, there 40, maybe 50, 60, 80. And then you have to take the whole lot. You can't take a few say, well, I just want these in large and these in medium and small. And these in extra large, if you don't take it all, they just move on to the next buyer.

There's nothing in the 11s and 12s anymore that was like three or four months ago.

Inspect and Buy:

Regarding gloves on the ground, they all say inspect and buy. But we been down this road so many times and it doesn't work here's why.

Many times people go down to inspect only to find a number of people fighting over the same lot. Typically then the buyer that gets it is the buyer who shows up with the deposit for the proof of funds. Sometimes it may end up with whoever was willing to pay the highest price. So 1) all these people who came down to inspect didn't get the lot and go away disappointed. 2) if you got the lot you its likely you have to pay a lot more than you thought.


The best way to go about acquiring gloves on the ground is to put a deposit down or show a proof of funds so the lot owner can take it off the market and hold it for you temporarily. Then you go down and inspect it. That's our approach so we don't waste our time, your time or the lot owners time chasing ghosts.
