Laboratory assessment of samples collected in national population-based surveys have become increasingly feasible by adapting technological innovations to statistical requisites. Historically many diagnostic tests required complex equipment, excellent infrastructure, and highly trained personnel. Statistical sampling and data collection procedures require “field-friendly" technology. This paper will review the technological innovations in laboratory technology that may be useful in national population-based sample surveys in less developed countries. A variety of biomarkers will be evaluated with consideration given to sample size requirements, logistics, and policy implications. Experience with biomarkers, including anemia, vitamin A deficiency and HIV is reviewed. The expansion of the use of biomarkers in large national samples surveys is considered. Despite its feasibility and cost-effectiveness, choosing an appropriate technology will depend on the purpose of the test and other decisions about informing and treating participants.
Learning Objectives: At the conclusion of the session, the participant will be able to: 1. Describe innovations in laboratory technology that increase feasibility of biomarker sampling and analysis in population based field surveys of less developed countries (LDCs). 2. Summarize experiences with population-based studies of anemia, vitamin A, and HIV in LDCs. 3. List sample size requirements, other logistical considerations, and policy implications associated with population surveys of several important biomarkers in LDCs.
