What indicators allow the measurement of the efficiency of genetic tests?
The global efficiency of a genetic test is measured by three principal indicators: analytic validity, clinical validity, and clinical usefulness. The analytic validity of a test is determined by its capacity to identify a given genotype (the genetic constitution of a cell, an organism, or an individual) with precision and validity. Clinical validity corresponds to the ability of a genetic test to detect or predict the presence or absence of a phenotype (physical characteristic) or a disease. Finally, clinical usefulness concerns the contribution to clinical decision-making and improvements in individual health that a genetic test can make.
