Primary hyperaldosteronism in England and Wales: a review of the use of a Supraregional Assay Service laboratory for the measurement of aldosterone and plasma renin activity.
To ascertain the use being made of a Supraregional Assay Service laboratory in the diagnosis of primary hyperaldosteronism, follow-up data were obtained on 60 patients in whom the diagnosis was suggested by the biochemical results. In 36 patients an adrenal adenoma had been removed; 14 patients had evidence of an adenoma on CT scan; 10 patients were presumed to have bilateral adrenal hyperplasia. The data used to make the diagnosis of primary hyperaldosteronism and to assess the likelihood of the presence of an adenoma indicate that patients studied at 40 centres in the UK show results very similar to those of North American series where large numbers of patients have been described but all have been studied in the same centre. The majority of patients in our series were treated at the hospital at which the diagnosis was made, thus avoiding referral to a centre distant from the patient's home and indicating that the service was being used as originally intended when the Supraregional Assay Service was set up.
