Aliquot specimens

An aliquot is a specimen that is derived from a primary specimen

An aliquot is created by processing the specimen collected at a participant’s visit into smaller specimens. For example, if 10 mL of blood was collected during a visit, that 10 mL tube is the primary specimen. It may be processed then into smaller, 1 mL tubes of double-spun plasma. These 1 mL specimens are the aliquots in LDMS.
