Our Samples

Read about our biological sample resource and how they might help your research. We welcome proposals for sample access.

Participants of the SFHS who attended a research clinic provided biological samples (including blood and urine) for genotyping and other assays. Saliva was provided for DNA extraction by a subset of participants not attending a clinic and was used for DNA extraction for an additional 984 participants from whom blood could not be obtained. We have a number of aliquots of each sample for each participant. Basic biochemistry assays were performed on the baseline serum samples measuring creatinine, glucose, potassium, sodium, urea and cholesterol levels.
