= Ranolazine Trial - approximately 20 participants = Participants will be allocated a two-digit RIAS number Use 'last name' as RIAS01 etc Protocol Participant ID as '01' etc Simplified protocol in caTissue, primary samples being designated as 'plasma' although blood is being drawn to derive plasma. == Visit 1 == Primary sample in EDTA tube: label 01-01 Plasma. Two 1ml aliquots taken and frozen: 2d barcodes == Visit 2 == NO SAMPLE == Visit 3 == Primary sample in EDTA tube 01-03 Plasma. Two 1ml aliquots taken and frozen: 2d barcodes == Visit 4 == Primary sample in EDTA tube 01-04 Plasma. Two 1ml aliquots taken and frozen: 2d barcodes. == Storage locations == Each visit generates 2 samples - one in each freezer. Boxes to be restricted to the Ranolazine protocol. Locations: 3/D22/1/x and 4/D22/1/x = TO DO = Add user accounts in caTissue for: Robyn Lotto Claire Peers Gerry !McCann Create protocol Create storage locations - one rack in each freezer (labelled 'small study rack') specific for this study, and a box on each of those racks.
