From the 5 anticoagulants studied, Na citrate and K2EDTA proved to be the best choices, and pH of 7,5-8 was ideal for following in vitro glycation process. No real difference occurred between samples diluted with saline and Hepes buffer. Samples with intact blood cells presented a better kinetics compared to hemolized samples.
