Reports from University of Belgrade Describe Recent Advances in Medical Biochemistry (The Influence of Various Sample Storage Conditions and Sample Bacterial Contamination On Concentrations of Routine Biochemical Parameters).

A recent study conducted by researchers at the University of Belgrade in Serbia examined the stability of basic biochemical parameters in samples under different storage conditions and freeze-thaw cycles. The study also investigated the presence of bacterial contamination in routine laboratory work. The results showed that urea and glucose concentrations remained stable, while lipid concentrations exhibited complex patterns of change. Additionally, no bacterial growth was observed in samples stored with sodium-fluoride/potassium oxalate plasma. The findings suggest that sodium-fluoride/potassium oxalate plasma may be a suitable option for analytical procedures where bacterial contamination can affect the quality of analysis.
