We present an improved fructosamine assay for use with the Technicon RA-1000 analyzer. Features of this assay include: specimen throughput of 100 per hour, within-batch CV of 1.5%, between-batch CV of 2.4%, standard curve linear up to 24.9 mmol of fructosamine per liter, and good correlation (r = 0.82) with hemoglobin A1.
Summary1. A correlation between platelet aggregation and the plasma enzyme(s) ability to degrade Adenosine Diphosphate (ADP) has been confirmed.2. This plasma activity has been shown to be reduced in 6 patients with uraemia in whom platelet aggregation was demonstrably impaired but not in two whose platelet function was normal. The incorporation of 14C labelled ADP-8-14C was also only reduced in uraemic patients with abnormal platelet aggregation.3. These findings are discussed with particular reference to possible implication in mechanism involved in ADP aggregation of platelets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
