Feasibility and cost-effectiveness of at-home self-sampling screening for type 2 diabetes: a pilot screening study in Denmark
Authors' conclusion
The study suggests that screening for type 2 diabetes using at-home self-sampling HbA1c tests, targeting individuals aged 50-75, who have not had their HbA1c measured the past 2 years, is feasible and cost-effective in Denmark.

Main finding
As reported in the abstract
9 months
- Returned a blood sample
- About 38%
- HbA1c ≥48 mmol/mol (6.5%)
- 1.7% (50/2913)
- Screening costs per screen-detected with T2D
- 1.207
- Estimated reduction in healthcare costs and productivity losses per screen-detected, if diagnosis moved forward by 3 years
- €1514
- Total social return ratio
- €1514/ €1183=1.28
