Liquid control materials for haemoglobins A2 and F: a one-year interlaboratory evaluation.
Stabilised haemolysates, to be stored at -20 degrees C in the liquid state, have been evaluated in an interlaboratory trial: haemoglobin A2 and haemoglobin F levels were stable for at least 1 year. Since the materials can be very easily prepared in each laboratory, they appear to meet the requirements for use in internal quality-control schemes, for the assay of both haemoglobin fractions.
