The development of spontaneous hyperthyroidism following primary hypothyroidism is an unusual occurrence. We report two cases of confirmed primary hypothyroidism who subsequently became hyperthyroid. Thyroid stimulating antibodies were present in the sera of both patients during the hyperthyroid state. The significance of this sequence of events is discussed and a possible explanation proposed.
A retrospective analysis has been made of patients who had been classified (on the basis of measurements of serum thyroxine and thyroid hormone uptake test) as equivocal thyrotoxic (273 patients) or as equivocal hypothyroid (352 patients). The final diagnosis of these patients has been traced from their medical records. The results illustrate that control groups of euthyroid, thyrotoxic, and primary hypothyroid subjects differ from these equivocal groups. The populations initially classified as equivocal have been used to redefine the combinations of values obtained in the serum thyroxine and thyroid hormone uptake test which must be classed as equivocal. Using this redefinition, it is shown that a number of additional tests had been carried out when it could now be predicted with confidence that no useful new information would be obtained. The procedure described is not limited to tests of thyroid function and could easily be applied in most laboratories to redefine the ranges of results classified as equivocal.

The total cost of performing diagnostic tests in a hospital laboratory during one year was assessed. The largest single item of expenditure was the cost of the salaries of the technical staff, while the cost of reagents (including radiopharmaceuticals) was relatively small. The total costs of carrying out diagnostic tests are much higher than is often recognised by those who request them. The use of relatively expensive, commercially available assay kits saves time and gives good value for money. It may be worth taking this into account when planning hospital budgets.
