Methods Venous blood from 20 healthy volunteers and 20 unselected patients attending a
general medical clinic was taken into lithium heparin tubes and an aliquot immediately …

Background The stability of analyte concentrations in plasma after prolonged contact with
blood cells in uncentrifuged lithium-heparin gel tubes was studied. Methods To investigate …

By analyzing whole blood containing no anticoagulants (uncoagulated whole blood)
immediately after collection, we evaluated the relative changes in the concentrations of …

Pre-analytical variables, eg, specimen collection, transport, and storage, can contribute
significantly to inaccurate pH, blood gas, and electrolyte values. The International …

The choice of anticoagulant for blood gas and electrolyte analysis has constantly been
changing in an attempt to minimize anticoagulant induced pre-analytical errors. A variety of …

In clinical chemistry two different quantities are determined for electrolytes: 1) Electrolyte
concentration (total) in serum (S) eg S-sodium (mmol/l), S-calcium (mmol/l). 2) Electrolyte …
