The use of desk-top cholesterol analysers in general practice.
An examination of the use of desk-top cholesterol analysers was performed within 10 practices in Kirklees, West Yorkshire. The survey entailed a questionnaire survey of the principal users of desk-top cholesterol analysers and the analysis of two laboratory quality control samples. The majority of practices used Boehringer Lipotrend, with frequency of use varying from < 5 tests/week to a maximum of 20/week. Training by manufacturers was absent in four practices. The maintenance of analysers was inadequate in seven practices as was quality control in five practices. Analysis of laboratory quality control samples showed about 50% of results within 0.5 mmol/l of mean, but 20.6% differed from mean by > 1 mmol/l. The coefficients of variation were 18% and 20% respectively. The use of desk-top cholesterol analysers is increasing in general practice, but improvements in training and quality control are necessary to ensure precise and accurate results with near-patient testing.
