Follow-up survey 2024

LifeGene began its data collection in September 2009. It contains information from a total of 52,107 participants and consisted of two phases. The first part was a web-based questionnaire and the second a health test with sampling. The sampling collected blood, serum and urine from more than 29,500 participants, these are stored at KI Biobank. Sampling was done on one occasion only and the sub-moment ended in 2018. The web-based questionnaire was answered annually during LifeGene's active period.
