[Venous stasis and orthostasis as factors influencing fructosamine concentration]

The concentrations of high molecular weight blood constituents are influenced by the increased intravascular pressure at sample collection. The impact on the fructosamine concentration was compared with that on total protein, plasma protein, electrolytes, and protein bound analytes such as calcium. The results show that fructosamine concentration behaves similar to that of total protein and albumin with change in resting position and venous-stasis.
