Results from EFF and SAF domain answer this question perfectly. As there are only minor differences between the two tests and the consequences are identical no important differences in benefits and risks have to be taken care of.
The key issue is the implementation as population based screening. The choice of the test does not influence issues of justice. An indirect question with regard to justice can arise from differences in cost of the two tests. Cost differences in this program are opportunity costs for other potential interventions in the field of screening or in the wider field of health care or public health. So only the indirect consequences of the budget impact of a decision between the two tests may influence fairness or solidarity. This indirect impact was outside of the scope of the assessment. In an indirect way such questions are included in economic evaluations as willingness to pay threshold.
