🧪Here's an updated roundup of highly reliable, easy-to-use molecular covid tests on the market today!

Accuracy stats, cost per test, and citations throughout. 🧵 At-Home Molecular Covid Testing: Regular rapid tests don’t produce reliable negative results. Luckily, there are at-home molecular tests that have an accuracy approaching what you get from PCR tests, the gold-standard in viral detection! Increase the reliability of your covid testing by using one of these fast at-home molecular tests. Pictured are four test readers, the clean air club cloud logo, and a sticker that says "update!"
🏆 Coming in at #1, we have the Pluslife Minidock!

This one has an amazing 98.3% test sensitivity -- meaning if it shows a negative result, you can rely pretty heavily on that.

Pluslife Covid test: Reader cost: $310 (DM Clean air club for discount) Test cost: $8 Sold via Altruan.com DM Clean Air Club for discount code Test sensitivity: 98.3% (how reliable a negative result is) Test specificity: 99.3% (how reliable a positive result is) Pluslife also has tests for HPV, Strep, Mpox, Influenza A+B, RSV, and viruses that affect household pets Citation: Zhu et al., “Trial of the Pluslife SARS-CoV-2 Nucleic Acid Rapid Test Kit: Prospective Cohort Study” JMIR Public Health Surveill. 2023; 9: e48107.

🥈 At a close 2nd place, the Metrix molecular test has an impressive 96.7% test sensitivity and a much cheaper startup cost (though this is negated over time by the more expensive tests). Also a really good system to get.

Metrix Covid Test: Reader cost: $50 Test cost: $25 Test sensitivity: 96.7% Test specificity: 99% Cost goes down when you buy the reader and tests bundled Citation: “Aptitude Matrix COVID-19 Test: Instructions for Use For Healthcare Providers” https://web.archive.org/web/20230511163447/https://www.fda.gov/media/162403/download
🥉 In third place we have the 3EO system. In my opinion, the only reason to get this one is if you don't have access to Pluslife or Metrix. 🤷‍♀️

It's still good, but it's outperformed on both cost and test sensitivity by Metrix.

Citation: web.archive.org/web/2023101721…
3EO Covid test: Reader cost: $150 Test cost: $20 Test sensitivity: 95% Test specificity: 100% Cost per test goes down slightly when you buy bundles Citation: “3EO Health: COVID-19 Test Instructions for Use” https://web.archive.org/web/20231017215248/https://www.fda.gov/media/172392/download
☁️ Honorable mention: Lucira combined Covid & Flu test.

The sensitivity isn't great (only 88.7%). However, it still FAR outperforms rapid antigen tests (like what's at Walgreens) & it's a self-contained, single-use test. There may be some situations where that's desirable. Lucira Covid & Flu test: Reader cost: n/a Test cost: $50 Test sensitivity: 88.7% Test specificity: 99.7% ** Each Lucira Covid & Flu test + reader is single-use Make sure you purchase the Lucira Covid & Flu test, NOT the Lucira “Check It” Citation: “Performance Evaluation of the Lucira COVID-19 + Flu Test” https://clinicaltrials.gov/study/NCT06141824. Note that PPA and NPA were used for the sensitivity and specificity stats above.
For context: The rapid covid tests at pharmacies today are VERY bad at ruling out covid (their negative reliability hovers around 25%)😫

By contrast, these molecular tests produce negative results that are over 95% reliable! 😀

pubmed.ncbi.nlm.nih.gov/36379401/
I hope you're able to improve the reliability of your at-home covid testing 💙

And if you can afford one of these, that means you can afford two of these. Buy an extra system and give it to someone who can't.

We need to be ready for even further criminalization of mask wearing in the wake of the NYC assassination. The mayor is already ramping up his usual anti-mask rhetoric, associating masking with "criminality" and deference to the surveillance state as patriotism.
Look out for any rhetoric suggesting "law-abiding people have nothing to hide" or that public safety depends on further criminalization of masks.

Privacy, community care, and self-defense during an ongoing pandemic are intertwined, and their threats will be, too.

The EPA just released new guidance on preventing viral spread indoors:

☁️ Air purifiers
☁️ Upper-room UVC
☁️ Increased ventilation

The science is so simple and so clear at this point. Let's do it.

epa.gov/indoor-air-qua…
They reference the CDC's latest guidance of 5 air changes per hour as the minimum standard for clean indoor air, signaling a convergence across federal agencies.

They also reference our preferred standard, ASHRAE 241, which is MUCH safer and could actually stop the pandemic. A table listing various occupancy categories, like restaurants, gyms, reatil, warehouses, and health care rooms. It then shows the recommended Air changes per hour for each setting, ranging between 1 and 60.
Our founder presented this same information to the U.S. Access Board earlier this year:

Adopting ASHRAE 241 in *all* public indoor spaces is the best shot we have at ending the pandemic. It's a matter of accessibility, public health, and justice.

☁️ 50+ ways to show up for people with Long Covid & ME/CFS ☁️

Over 400 million people around the world have Long Covid, and millions more have ME/CFS. Here are concrete ways you can show up for them so that nobody gets left behind! 🧵 50 plus ways to show up for people with long covid and ME/CFS so that nobody gets left behind. The clean air club cloud logo is in the bottom right.
Before you offer help, consider these four points: Before you begin: Remember: LC and ME/CFS are extremely isolating. We can’t leave our community behind! Center consent when you offer help. Disabled people are the experts on what they need and want. Don’t make this about you. Showing up for one another is a normal part of being in relation. Consider picking one or two actions and making them recurring. Stability is important!
1. Drop off groceries
2. Send a meal delivery gift card
3. Bring home-cooked meals
4. Chop ingredients for the week
5. Take their kids out
6. Do an at-home activity with their kids
7. Pick their kids up from school

Nasal irrigation is one of the cheapest covid precautions you can add to your routine! 🧵 Nasal Irrigation for Covid-19: cheap, effective, and well-tolerated. An illustration of a woman doing a nasal rinse is in the center with the clean air club logo in the bottom right.
💧Nasal rinsing is the process of rinsing a saline solution through your nasal passages to clear out mucus, debris, and allergens. It also reduces the chances you'll become infected when exposed & reduces illness severity and duration if you're infected. (citations in 🧵)
There are great studies backing up nasal irrigation (rooted in the ancient practice of Jala Neti)

Here's one: ncbi.nlm.nih.gov/pmc/articles/P…
“Overall, patients with positive swab tests experienced substantial viral load reduction, became PCR-negative faster, and had milder symptoms than untreated patients. Hence, repeated application of [nasal saline irrigation] can be recommended for fastening viral clearance, symptom relief, and prophylaxis against respiratory infection, as has been increasingly proposed in (self-care) treatment or hygiene prevention guides for COVID-19.” Citation: Huijghebaert et al., “Saline nasal irrigation and gargling in COVID-19: a multidisciplinary review of effects on viral load, mucosal dynamics, and ...

🧪 Not all covid tests are made the same!!

Would you rely on a smoke detector that only beeped during 28% of fires?

If not, then don't rely on one regular rapid test that picks up on covid only 28% of the time. 🥴

Stats below!! A bar graph comparing the sensitivities of different tests. The title reads "Covid test sensitivity: If you have asymptomatic covid, these are the chances that each test will actually detect it and show a positive result." 1 rapid antigen test is at 28%; 2 rapid antigen tests 48 hours apart is 63%. Lucira covid and flu test is 89%. 3EO molecular test is 95%. Metrix is 97%. Pluslife is 98%. "Takeaway: negative results on regular rapid tests don't tell you much. Citations in caption."
