An anti-semenogelin antibody is fixed at the test line. If human semenogelin is present in the sample, it will form an antigen-antibody-colloidal gold complex upon deposition. These complexes react with the antibodies fixed at the test line to form a visible red line indicating the presence of human semenogelin, and therefore, human semen. [4]
The following tests are some examples of those that are used on hand specimens, or on field samples, or on thin sections with the aid of a polarizing microscope. Color; Color of the mineral. Color alone is not diagnostic. For example quartz can be almost any color, depending on minor impurities and microstructure. Streak
Most people who take a drug test take a presumptive test, cheaper and faster than other methods of testing. However, it is less accurate and can render false results.

The examination of handwriting to assess potential authorship proceeds from the above principle of identification by applying it to a comparison of samples of handwritten material. Generally known as ACE-V, there are three stages in the process of examination.
Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation.
