1. Study Purpose

   The purpose of this study was to determine the effects of storing serum at -20 degrees C for 1 year in primary gel separation tubes as opposed to transferring specimens to new plastic storage tubes on the measurement of anti-rubella IgG concentrations. Specimens were centrifuged and then refrigerated overnight in original collection tubes prior to experimental storage at -20 degrees C, either in same collection tube with new tops, or in a new plastic microtube.

   Summary of Findings:

   After 1 year of storage at -20 degrees C, no differences were found in anti-rubella IgG concentrations between the specimens stored in SST and those stored in plastic microtubes.
