[An attempt at quality control based on the recovery test in radioimmunoassay].
Quality control sera for radioimmunoassay (RIA) are supplied commercially, as lyophilized sera will become more common due to the ease of their usage, good reproducibility and the constant supply. This paper demonstrates the improvement in accuracy and precision of analyses proved over the year by the tracking of recovered and recommend proper analysis simplified enough for routine application. The recovery test for quality control is described and can be used to control intra-day variation with R values and to control long-term intra and inter-day variation and suits the purpose that is not supported by commercial control sera well.
