At-home tests: Help or hindrance?

Many people have used at-home medical tests to detect COVID-19. Other home tests are available that can screen for, diagnose, and monitor dozens of health conditions, including pregnancy, infections, cholesterol and blood sugar levels, and colorectal cancer. The tests are accessible and convenient, and results may spur people to seek necessary treatment. But test results may be inaccurate or confusing, provoking unneeded or risky further testing or treatment. People should tell their doctors if they use at-home medical tests.
