Dear colleagues, In the WHO list of sample stability (http://whqlibdoc.who.int/hq/2002/WHO_DIL_LAB_99.1_Rev.2.pdf) it is stated that glucose is stable for only one day in serum at -20ºC. This seems rather odd. Does anyone have a source that claims a longer stability, like 1 year or so? Best regards, Bart Ballieux Dr.Ir. B.E.P.B.
