T-Cell Testing from T-Detect
I was listening to an episode of Dr. Peter McCullough’s “America Out Loud” show , and he mentioned a company called T-Detect that provides T-cell testing to determine if you had previously been infected with SARS-CoV-2 and thereby have acquired T-cell immunity. I’m wondering if anyone can comment on this company and any experiences you’ve had with them.
I actually got sick last year in the “It’s just the flu” phase with Covid-like symptoms, and I even have some very minor (i.e. not at all debilitating) ongoing lung congestion that just won’t seem to clear. I work as a contractor at a facility that has imposed a vaccine mandate, and it is possible that I could get asked to participate. I’m thinking that if I can prove natural immunity I might be able to get by without jab, as my manager is pretty reasonable.
Just figured I’d throw this out there. Would love to hear your thoughts and/or experiences if anyone has some!
She had to sign up with T-Detect and buy 6 testing kits to do this for our remote area. Those who live near a walk-in branch of the major blood drawing and testing company that T-Detect uses, can order a kit from T-Detect and take it to the lab, to have your blood draw done. And then send it in for testing, I believe. Or you can pay to use a mobile blood draw service that is authorized by T-Detect. So many, many places will not be able to make use of the test, at least for now.
I ended up negative, after wondering if I had contracted Covid very early, or if I may have had Sars 1 many years ago. Not sure if their test would detect that or not. But, I would have made me feel more secure out there if I had tested positive. Yes, if you were mandated, maybe you could get a pass if you were positive for T-cells. It costs about $200.
It seems to be reputable, as it has an FDA emergency approval…for what that is worth. Good luck with it.
I’m interested in this test as well. Pls update us about your experience.
Don’t forget to accumulate the data on the protection from natural immunity (recovering from the virus)
Of 11,000 healthcare workers who had proved evidence of infection during the first wave… in the UK …, none had symptomatic reinfection in the second wave
Not one of the 1359 previously infected subjects at Cleveland Clinic who remained unvaccinated had a SARS-CoV-2 infection. https://www.medrxiv.org/content/10.1101
Chris covered this data in a recent video
< 1% of 835,000 unvaccinated, previously infected people in Israel were reinfected according to recent data.

Six weeks ago, my wife and I each bought a T-Detect test and had a blood draw from LabCorp. We got results in 2 weeks – both negative. We had previously had our antibodies checked in June 2020, again negative. These results surprised us with no evidence of exposure/recovery despite both of us not wearing masks, getting vaxxed, or avoiding crowds for the last 18 months. We do take Vit C, D, zinc, niacin, NAC daily so maybe that helps. Maybe we have another cross-immunity from other cornonaviruses, or maybe we are just lucky?
The test results don’t report a threshold used for IgG/IgA activity, nor which T memory cell receptors they used, so it’s a little hard to interpret what exactly a negative result means. The FAQ for T-Detect says that memory T cells may only be detectable for 5 months, which surprised me since I had read this paper that showed active SARS-COV1 memory T cell response to SARS-COV2 in test subjects 17 years later https://www.nature.com/articles/s41586-020-2550-z
If I was taking the test to prove a previous infection to avoid a mandatory vax, I think it’s worth the money, IMO. Especially if you know you’ve had COVID by either symptoms or a PCR test with low Ct values.
Relating to my negative T-Detect test results – I researched wild bat populations for 20 years, in the process handling ~2500 live bats at various locations and walking into numerous caves with 10,000+ bats flying around. Could’ve given me some previous exposure to random coronaviruses most people don’t encounter for sure. Maybe I vaxxed myself and didn’t know it?!?
Was planning the same, still not sure if it is not just another scare-yourself-for-big money-into-vaccination stuff. They have description, yes, (https://www.fda.gov/media/146481/download) but I have seen accredited labs to hide politically undesirable test results for other issues (Lyme, measles), so I am kinda not sure… 220 dollars… I know for sure I had infection (the one and only loss-of-smell-without-congestion event in my life), but it was even before quarantine, so no test was made at that time. If I decide to go for this test I will report here guys… Wish me luck.
@JimboJim: Very, VERY likely. There is even possibility to get cross-immunity from cat- coronaviruses, in the case you have contact with free roaming cats… And possible cross-immunity from other seasonal coronas: “There are four types of endemic coronaviruses (229E, NL63, OC43, and HKU1) that regularly circulate through humans, causing the majority of respiratory tract infections”( https://www.bmj.com/content/372/bmj.n99 )
Appreciate all of the comments. Finally got my blood draw done today at local Labcorp location, took a while because I couldn’t get away from work for long enough to get to one of the local locations. Anyways, results should be pending soon.
Of course, with full vaccine approval apparently coming, and employer mandates soon to follow, I don’t think a positive result will be much use. Will keep everyone posted regardless.
Just closing the loop on this one. My results for the T-Detect test unfortunately came back negative. On the fortunate side, the facility that I work for is scrambling to get things back up and running after Hurricane Ida, so I probably have some time before any mandates get put in place.
In the event that my employer mandates, I will delay, and perhaps fight. Even if I lose, I’m not a huge fan of my current position anyways, and I’ve prepped for this enough through savings and other means so that I have enough runway to relocate.
Anyways, enough rambling, I have a refinery to help get back up and running!
