Objective: Glucose levels decrease in whole blood in vitro, but there are several methods
that minimize the loss, including special tubes and ice. This study evaluated whether …

Background: Conflicting information is available regarding the stability of glucose
concentrations in frozen plasma samples. Clinical trials could benefit from such long-term …

Precise measurement of plasma glucose is essential in evaluation of diabetes. In vitro
decreases in glucose concentration due to glycolysis may lead to missed diabetes …

Background: Previous studies of participants with plasma glucose concentrations at or near
the glucose reference range demonstrate glucose loss following delayed separation and …

Objectives Blood collection tubes containing citrate lower pH, thereby inhibiting glycolysis.
When compared to other additives, they introduce an over-estimation in measured glucose …

Objectives This study was designed to compare glucose values in serum or lithium-heparin
samples immediately centrifuged with those paired specimens collected in tubes containing …

Measurement of blood glucose is a standard biochemical test requiring optimum
preanalytical sample handling. Glucose measured in plasma from tubes containing sodium …

Plasma glucose levels provide the cornerstone of diabetes evaluation. Unfortunately,
glucose levels drop in vitro due to glycolysis. Guidelines provide suitable conditions which …

Background: Delayed sample processing can affect accurate glucose measurement. Our
aim was to investigate the stability of glucose in samples collected in serum, sodium …

In this issue of the Journal of Diabetes Science and Technology, Heenan et al 1 compare 41
adults' average capillary blood glucose meter (BGM) glucoses to their single central …
