It is very simple to use the test. You drop your sample into test vials, liquid, powder or pill. You watch the color under day light (white light) and compare with the pictures. Then you take 365 nm UV light point at the test vial and see if there is fluorescence and you get the right fluorescence color then it is pass, it contains the right substance. No fluorescence means fake product, no hormone inside. Then you have semi quantitative test, you compare color with color chart to determine the concentration.
