A false positive result on a contamination test occurs when the test indicates that a contaminant is present in an uncontaminated substance; conversely, a false negative result indicates an absence of contaminant that is, in fact, present. To accurately detect mercury contamination in water supplies, researchers should use the laboratory test that has the lowest proportion of false positive results.
