Evaluation of serum separator tubes as a mail transport device in primary health care
Sammanfattning
Serum separator tubes were evaluated as a serum separator system and a mail transport device. Using conventional tubes as controls, 26 serum constituents were examined. Thirteen constituents had concentrations that were different from the concentration in the conventional tubes. When medically important coefficients of variations were taken into account, however, the changes of only two constituents (potassium and cobalamin) were regarded as important.
