Abstract
: The performance of the BD Vacutainer: Tubes were drawn by routine venipuncture from 42 subjects according to a randomized draw order. Tubes were processed and centrifuged according to recommended handling procedures. Serum and plasma from the comparison tubes were aliquoted to secondary containers prior to analysis. Specimens were then tested for selected special chemistry analytes at two time intervals (initial time and after 24 h storage). Analytes tested included thyroid stimulating hormone, free thyroxine, total thyroxine, follicle stimulating hormone, luteinizing hormone, ferritin, cortisol, vitamin B12, folate, and testosterone. The data were collected and analyzed by analysis of variance and mean bias comparisons.: The performance of the BD Vacutainer: The BD VacutainerClin Chem Lab Med 2009;47:358–61.
