Table 2 Knowledge of the responding public health professionals regarding predictive genetic testing for chronic diseases

From: Are public health professionals prepared for public health genomics? A cross-sectional survey in Italy

Variables Agree Uncertain Disagree
% % %
Predictive genetic tests are able to identify genotypes which themselves do not cause the disease but modify the risk of developing it (788)a 86.6 9.0 4.4
Lifestyles, socioeconomic factors and pollution exposure cannot modify or influence the risk of disease due to a genetic predisposition (788)a 14.2 10.4 75.4
The analytic validity of a predictive genetic test is related to the accuracy of the laboratory test in identifying a specific genetic characteristic (788)a 70.6 25.6 3.8
The clinical validity of a predictive genetic test is related to the power of the test to quantify the risk of developing the disease (787)a 63.0 24.1 12.8
The clinical utility of a predictive genetic test is related to the power of the test to improve the health status of the subject (787)a 68.0 20.8 11.2
Performing predictive genetic tests should not necessarily be associated with genetic counseling that includes information, informed consent, and discussion of the results (787)a 11.8 13.2 75.0
Recommendations/guidelines produced by national/international organizations about the use of some predictive genetic tests already exist (786)a 47.1 49.1 3.8
