You have probably heard the expression “medicine is not an exact science” and not considered what they meant until faced with a severe illness or a crisis like COVID-19. Today, we sit by and watch top doctors and researchers scramble for cures, treatments, and adequate testing to help put society back on its proverbial feet. The headlines adequately reflect the adage as we read about flawed antibody tests and false-negative COVID tests, which taint our understanding of the epidemic. Research is seldom a linear process, nor is the practice of medicine. Our bodies are composed of interdependent systems with complex structures rooted in our DNA and genotypes.
