Official title
The Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE Study) Capillary Blood Collection: A Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This pilot study is planned to validate the comparability of HbA1c results obtained from whole blood collection via venous phlebotomy versus a capillary collection of whole blood. The participant will self-collect capillary blood into HbA1c prep vials containing a buffer; these prep vials will be sent to the CBL at ambient temperature via US Postal System (USPS) mail. The feasibility of self-collection of these capillary samples by GRADE participants will also be evaluated.
