Indicators
Molecular detection of Chlamydia trachomatis and Neisseria gonorrhoeae nucleic acid.
Glossary Term
The probability that a test will produce a true negative result when used on non-effected subjects as compared to a reference or "gold standard". The specificity of a test can be determined by calculating: number of true negative results divided by the sum of true negative results plus number of false positive results.
Performance Metrics
Tests
An index of the variation in the size of the red cells and can be used to detect subtle degress of anisocytosis. It is computed directly from the RBC histogram and is calculated as a standard statictical value, the coefficient of variation of the red cell volume ditribution (ratio of standard deviation and mean copuscular volume).

Molecular detection of M. tuberculosis complex, with or without rifampicin resistance markers.
For professionals
Tests
A modification of the Bethesda Assay where the pH and the protein concentration of the test mixture is further standardized, such that the factor VIII coagulant activity (FVIII:C) in the test mixture is less prone to artifactual deterioration and the test has improved specificity.
