Until 1979, the out-of-hours chemical pathology service was the conventional on-call service in which the medical laboratory scientific officers (MLSOs) carried out analyses at the direct request of clinical staff. In 1980, during an industrial dispute, junior ward doctors were trained to use three simple instruments which are maintained by the chemical pathology department. In January, 1981, when the dispute was settled, the doctors continued to use these instruments. Analyses they could not make were done by the MLSO on call, but only after the requests were monitored by a chemical pathologist or biochemist. The result was an 80% reduction in the number of calls. When the monitoring was withdrawn in 1983, there was some increase in the number of MLSO calls, but this was still 35% less than that with the conventional system despite a 4-fold increase in the total number of analyses done out of hours between 1979 and 1984. Surveys in 1984 and in early 1985 revealed that most doctors preferred using the instruments to asking an MLSO to make the analysis.
直到1979年，非工作时间的临床化学检验服务还是传统的随叫随到服务模式，即医学实验室科学官员（MLSOs）应临床工作人员的直接要求进行分析。1980年，在一场劳资纠纷期间，初级病房医生接受培训，学会使用由临床化学检验部门维护的三种简易仪器。1981年1月，纠纷解决后，医生们继续使用这些仪器。他们无法进行的分析由随叫随到的MLSO进行，但请求须先由临床病理学家或生物化学家审核。结果是呼叫次数减少了80%。1983年取消审核后，MLSO的呼叫次数有所增加，但尽管1979年至1984年非工作时间的分析总数增长了4倍，此时的呼叫次数仍比传统系统少35%。1984年和1985年初的调查显示，大多数医生更喜欢使用仪器进行分析，而不是请MLSO来做。
