Comparison of seven biochemistry analytes stability in serum separator and plasma tubes

The effect of recentrifugation of serum separator tubes on concentration of serum analytes.

In clinical laboratories, sometimes there is a need to recentrifuge the original tubes ("clot" tubes) in order to better clarify and clean the serum or plasma for further analysis. Also, the original tubes are recentrifuged to ensure there is an adequate volume of serum or plasma for multiple repeating or different tests, and/or to run additional tests that are ordered hours after the original ...

Stability studies of common biochemical analytes in serum separator tubes with or without gel barrier subjected to various storage conditions

INTRODUCTION The collected and shipped blood samples are exposed to a various extra-analytical factors prior to analysis. The aim of the study was to determine the stability of analytes in serum gel tubes and plain tubes exposed to a range of storage temperatures and times after centrifugation. MATERIALS AND METHODS Fifteen healthy volunteers were recruited and venous blood was collected into...

Comparison of Plasma and Serum Biochemistry in Cat

The most important aim of a clinical laboratory is the correct performance of analytic procedures that yield accurate and precise results aiding patient diagnosis and treatment. In recent years there has been an increasing effort by international committees and working groups to develop quality standards for the pre-analytical phase including the proper use of anticoagulants in specimen collect...

Iodinated contrast media interfere with gel barrier formation in plasma and serum separator tubes.

Comparison of digoxin concentration in plastic serum tubes with clot activator and heparinized plasma tubes

INTRODUCTION Sample type recommended by the manufacturer for the digoxin Abbott assay is either serum collected in glass tubes or plasma (sodium heparin, lithium heparin, citrate, EDTA or oxalate as anticoagulant) collected in plastic tubes. In our hospital samples are collected in plastic tubes. Our hypothesis was that the serum sample collected in plastic serum tube can be used interchangeabl...
