A comparison of glucose concentration in paired specimens collected in serum separator and fluoride/potassium oxalate blood collection tubes under survey 'field' conditions.

Objectives: There are no direct comparisons of blood glucose values in samples collected with barrier serum tubes (SST) and NaF/potassium oxalate (NaF/KOx) plasma tubes. Collection of samples in SST tubes can offer considerable savings and specimen processing advantages for national level surveys.

Design And Methods: Serum and plasma samples were collected under 'field conditions' from a single draw of 3692 individuals participating in the Canadian Health Measures Survey.
