Biosocial surveys can explore biological pathways to disease risk, their association with social relationships and statuses, and build a population profile of clinically relevant measures. The design and conduct of biosocial surveys requires adaptation by both survey and biological researchers. The chain of events in collecting blood begins with the request for the nurse visit and ends with full or partial samples. This paper examines participation in the Wave 2 nurse visit of the English Longitudinal Survey on Ageing (ELSA) and the completeness of blood-derived measures. Analyses will focus on respondent and survey method related predictors of the multiple steps in the chain from eligibility to obtaining values for the biomarker. While blood-derived measures present the most contingencies, other biomeasures have multiple trials or eligibility determination. In addition to applying the appropriate weights to adjust for non-response, researchers should be aware of the measurement complexity in biosocial surveys.
