My wife and I got the IgM/IgG test that requires a blood draw, not just a finger-pr1ck. They also do the finger-pr1ck, same-day results test there. It is just a qualitative yes/no test.

2-3 days for results, they say. ArcPoint Labs in SugarLand.

I am fully aware that this is probably a complete waste of time, since these tests may produce positive results to non-SARS-COV-2 antibodies. But I was just curious, and my wife was really excited to put on real clothes and make the 30 minute drive to SugarLand. And wasting money somewhere besides Spec's seemed like a good deed for stimulating the economy!

I'll let y'all know the results, if anyone cares. Anyone else been tested?

Thank you comrade for your DNA...we will put it to good use!

Seriously...hope you both have antibodies!

I realize your joking but I'm seeing these kinds of comments a lot, and I think some people are serious.

I wonder if the people who are seriously thinking this are also concerned about blood tests, giving blood, flu tests, strep throat tests, getting their hair cut, cutting nails or any of the other methods where someone can get your DNA.

One of the more disappointing things I've read this week is the fact the antibody test - the tests that in my own mind would give a path out of this situation, potentially - aren't even positive for ONLY Covid 19 but also, as you mentioned, for other types of viruses. I struggle to see how they help as much as I thought they might if that is the case, and they can't be made more specific.

There is a family near me that all went to get this same test. They all tested positive. They went from being relatively good about shelter in place to going about their business as if there is no virus. They told my wife that at some point in October or November they were all sick and they think they all had the COVID 19 then.
So with positive tests, they completely changed their day to day behavior.

If you test positive, does it change yours?

Wouldn't that require both an antibody AND active virus test, at a minimum?

Some concerns I would have:
1) antibody test shows positive for viruses other than Covid 19 (antibodies formed due to illnesses from similar viruses)
2) I have antibodies but could still potentially spread the virus to others, would need to test if I am still an active spreader.

I'd be thrilled to get a positive anitbody test but might not feel cavalier about behavior instantly.

Are you going to get a shirt that says "Don't worry, I've got the body" so people don't yell at you for not wearing a mask?

One weak potential benefit to knowing you have antibodies to non SARS-CoV2 coronaviruses is the theory behind why young kids seem to be more resistant to SARS-CoV2... in that they pass around the common coronaviruses a lot more frequently that adults so they become more resistant to the novel strain.

One things to keep in mind -- not all tests produced by certain companies perform as well as others.



For instance the EuroImmun tests do not seem reliable.

Would be interested to know which test (from what company) you got or if the tech/staff even know the source.

some tests are better than others

I would expect blood draws to be a much better survey (although not as good for POC purposes)

So.....great plan to shut that resistance off with cower in place.

Per the FDA guy yesterday the labs doing these tests are required to provide the individual being tested with certain information and disclosures around the tests.

From their web site

Lab Based COVID-19 Antibody Immunoassay
15 minutes @ $175.00
The COVID-19 IgG and IgM Lab antibody screen is used for the qualitative detection of SARS-CoV-2 antibodies. This simple blood test will be performed on completely asymptomatic individuals. It determines if the patient has ever encountered the COVID-19 virus and if your body has possibly developed a functional immunity to the virus. Results are shared with the TX Department of Health and CDC for their statistical information. Response to the test will help guide your social distancing and work patterns.

Serious question: Isnt that the point? After waiting 4-5 days from the positive test if you still have no symptoms, why would anybody be concerned? Again asking seriously.

If I test positive for anti bodies. I am done with stay at home.

Carry copies of my test with me and do as I please.

I called the lab and got this info;

89.89 sensitivity 97.50 specifity covid 19 no cross for other viruses only if you had sars 1.

High quality lab testing with blood sample

I am a dentist that gets exposed to all sorts of crap so I would love to take a test and get a positive result. It would make me feel a little safer knowing that some part of my immune system seems ready to react to the virus.

I would still use PPE at work as required by law but I would be less worried about getting it from a grocery store or giving it to family members.

The concern is seemingly if you get a positive you feel you are immune and can go about your daily business. And others want to say but you tested positive for "another virus" and still need to shelter in place.

That doesn't make sense to me...so they specifically tested it against SARS 1 to get the specificity, but it has absolutely no reactivity to other corona viruses? Why would they even use SARS 1 to validate the test?

With what is known as of today...If my wife and I tested positive, I would probably be careful until I knew we were not asymptomatic carriers, either by PCR test or waiting long enough to know we were not sick. Probably still wear masks in public places so we don't look like selfish jackasses.

Of course, knowledge is changing rapidly. I would want us to be pretty sure a) we are protected and b) we can't spread to others, and c) Reinfection is not likely or at least likely to result in serious illness before we went out and about normally. And I am not one who is remotely into overreacting to this.

Yes, the concern for yourself would be dependent on the test - if it is a test that only shows antibodies due to a Covid 19 infection, no others, then you personally should be safe (even if these rumors of re-infections are true, it would be a mild case at worse I would think).

However, the concern for others is that there is not yet proof someone with antibodies - either over symptoms or never having had symptoms - can't spread the virus to others. WOuld still be good to not visit elderly relatives, etc, until more is known.

I am a dentist too and know that we are hit be aerosols all the time so I feel like we should have pretty strong immune systems. That being said I got really sick in December and I never get sick. It worried my staff because in the 12 years they have worked with me I have never missed a day of work for being sick. The last time I was sick was when I was pregnant with my son and he is almost 16 years old.

I would love to have this test to see if maybe that is what I had in December and it would make it easier when we get to return to treating our patients.

Also...97.5% is not that great. That would mean that if only 1% of Texas has or has had Covid, and you get a positive result, there is only a 40% chance you have the antibodies.

Took my family of five for testing last week and all negative.

Very disappointing because my wife and one daughter had terrible respiratory virus in February.

Figured we'd all had it.

But now with the finger ***** tests we took looking to have problems, we may need to do it again.

The specificity of the test (2nd column) represents the false positive rate and is, in my opinion, the most important thing to look at. False negatives are not necessarily going to be harmful to anyone's health, but the assurance that comes with a false positive could be very problematic.

A specificity of 98% may sound good, but it's actually pretty bad here. It means that around 2 out of every 100 people you test will be a false positive.

Let's say you test 1,000 people to see how widespread covid-19 really is. 40 people test positive. 20 of those tests (2% of the 1000) could be false positives. This doesn't mean it's not useless information in terms of guesstimating percentage of population affected, but it is completely useless to the individual who has been tested because they only have a 50/50 chance of actually having the antibodies.

The effect of false positives go way down when the disease is more widespread. If 400 people test positive, the false positive rate would still only be about 20 people. If you are one of those four hundred people you feel a lot more confident about actually having antibodies.

Any particular reason you went to Sugarland? Did you look at any other options in Houston proper? Also meant to ask, was it difficult to schedule?

Someone sent me a link to that lab. I live in Fulshear, so that was the closest. Very easy to schedule. When I scheduled, same day appointments were available.

Biggest problem here beyond the accuracy of the tests is the widespread assumption that if you have the appropriate antibodies, then you are immune. No one knows this to be true yet. Moreover, no one knows how long that immunity, if present lasts. It will take months to a year or more to know the duration of any immunity gained. For now antibody testing is worthless for decision making about activity restrictions. If you pay for the test this is something you should understand. The research is being done to answer these questions. If you just want to get out of the house just take a drive. I'm not recommending antibody testing to my patients as a way to make sure they are immune.

To say its worthless is projecting.

It may not make you conclusively 100% immune, but it is at least some level of insight with a high probability of at least temporary immunity (while not total immunity at least partial)

Spare your doom and gloom. Its not warranted here.
