Bedside biochemistry.

Technological advances in instrumentation and methodology now make it possible for several biochemical investigations previously performed in a central laboratory to be carried out in the wards, intensive care units, outpatient departments and other situations closer to the patient. Such arrangements can be beneficial to the patient, but only when careful consideration is given to instrument selection and maintenance, operator training, quality control and provision of adequate back-up in cases of instrument malfunction.

Validity of the consensus mean as the target value for a small External Quality Assessment Scheme.

Data from 2 years' operation of an External Quality Assessment Scheme covering 14 analytes and with some 60 participants is presented. Following the trimming of discrepant results and statistical 'outliers' (outside the range of +/- 3 SD from the mean), there was generally close agreement between consensus mean values for a specimen analysed on different occasions, by different groups of laboratories, or when using different analytical methods. An improvement in performance, indicated by a reduction in the average inter-laboratory coefficient of variation was found for 11 of the 14 analytes over the 2-year period.
