The examination might not spot the infection if you were recently infected or remain in the incubation at the time of the test. A modern-day fluorescent based immunoassay utilizes as the discovery reagent a fluorescent compound which takes in light or power at a specific wavelength and then produces light or energy at a various wavelength. The difference in between the wavelength of the excitation light and the emission light is called the Stokes change. The greater the change or difference in the wavelength the much less interference there will be by having the excitation light identified as component of the emission light. Recently a number of technological enhancements have taken place that has actually made it possible for the execution of a high sensitivity immunoassay system.
