You might wonder: How accurate is it? Well, it depends. Lateral flow tests are great at catching you when you’re most infectious. That’s why airlines love them—they help reduce the chance of someone coughing on the plane. Think of it as a filter, not a guarantee.
Are they perfect? No. You can have a negative test and still be early in the infection. But for a Fit to Fly certificate, it’s often enough. It’s about risk management, not scientific certainty. And for a quick, cheap, and surprisingly fun gadget, that’s pretty impressive.
So next time you’re doing a test, remember: you’re not just peeing on a stick—you’re watching capillary action in action. You’re a citizen scientist, proving you’re healthy enough to hike in the Alps. That’s cool. That’s science you can hold.
