An external quality assessment scheme for total bilirubin.
A regional quality assessment scheme for total bilirubin methods is described. The scheme provides liquid sera at three concentrations and allows method linearity to be assessed. The sera were shown to be adequately stable over the periods of assessment. An integral part of the scheme is quick feedback of comparative performance between and within participant laboratories. Data presentation has some novel aspects to it (a) the weekly report shows deviation from the weighed-in value and intra- and inter-laboratory variation (b) the 6-monthly summary gives the average performance of the best three laboratories as achievable precision. There is also dialogue with participants on all aspects of the scheme including the material provided.
