Valepositiiviset
Valepositiiviset refers to a situation where a test result incorrectly indicates the presence of a condition, attribute, or substance when it is actually absent. This is a common concept in diagnostic testing, scientific research, and statistical analysis. In medical contexts, a false positive means a person is diagnosed with a disease they do not have, which can lead to unnecessary anxiety, further invasive testing, and potentially harmful treatments. In screening programs, false positives can contribute to increased healthcare costs and public health burdens.
The occurrence of false positives is often related to the sensitivity and specificity of a test. Sensitivity
Statistical methods are employed to assess the likelihood of false positives and to minimize their impact.
