I went to get dental implants today, and there will be bleeding during the surgery. As per regulations, the nurse gave me four rapid tests before the procedure: Hepatitis C, Hepatitis B, HIV, and syphilis. It's a small box; they draw blood from my fingertip, put it in the test solution, and the results are in a few minutes. I was shocked. They can test like that? I checked online: this test has an accuracy rate of 95% to 99%.

You can buy this on JD.com; it's a must-have for home and travel. Pair it with the automatic lancing device shown in picture 2 for a painless test. And with the device shown in picture 3, it can even test your vitamin D levels at the same time.

I just realized how convenient this test can be.
