Abstract

Despite the increase in the number of inherited metabolic diseases that can be detected at birth using a single dried blood spot sample, the impact of false positive results on parents remains a concern. We used an economic approach - the contingent valuation method – which asks parents to give their maximum willingness to pay for an extension in a screening programme and the degree to which the potential for false positive results diminishes their valuations. 160 parents of a child or children under the age of 16 years were surveyed and given descriptions of the current screening programme in the UK, an extended programme and an extended programme with no false positives. 148 (92.5%) respondents said they would accept the screen for the five extra conditions in an expanded screening programme whilst 10 (6.3%) said they would not and two were unsure. When asked to indicate if they would choose to be screened under an expanded screening programme with no false positive results, 152 (95%) said they would, five (3.1%) said they would not, two were unsure, and there was one non-response. 151 (94.4%) said they preferred the hypothetical test with no false-positives. The mean willingness to pay for the expanded programme was £178 compared to £219 for the hypothetical expanded programme without false positives (p > 0.05). The results suggest that there is widespread parental support for extended screening in the UK and that the number of false-positives is a relatively small issue.
