Biospecimens Data Dictionary

Blood sample collection for CPTP began December 19, 2008 and ended on July 31, 2015. Approximately 50 mL of non-fasting blood was collected from each of 29,183 consenting research participants who attended a study centre. Post collection, blood samples were divided into 0.5mL or 1mL cryovial aliquots. Biomarker Analysis was performed on every participant and quantative variables were derived for each sample type collected.
