specificity – Greek translation

specificity ['spesɪ'fɪsɪtɪ] n

med. The probability that a medical test will correctly produce a negative test result for a person who does not have the condition being tested. In other words, a specific test is one that produces true negative results. For example, the specificity of the Western Blot is very high; the test seldom mistakes antibodies to other diseases as antibodies to HIV. For that reason, the Western Blot is used to confirm a positive enzyme- linked immunosorbent assay ELISA or other HIV antibody test. see also sensitivity, true negative
