There's a blood test that could detect disease 10 years before symptoms appear; here's how it works

Imagine signing up for a medical test that could predict your future health status — a tool that not only alerts you about possible ailments but also gives you ample amount of time to prepare, take precautionary and preventive measures! Seems like a dream, right? Turns out, science has made that dream a reality. Scientists have found that a simple blood test — a pinprick blood test — may soon spot signs of disease up to 10 years before symptoms appear, which might be a potential game-changer for prevention. Using a tiny drop of capillary blood, researchers can measure hundreds to thousands of molecules (proteins, metabolites, and markers of cell damage) and build “signatures” that point to future risk of cancer, heart disease, diabetes, dementia, and other conditions.
