Editor, – I was interested in the article 'Prostate specific antigen', by Dr J.V. Wells (Aust Prescr 1993;16:37-9), but very disappointed to find no hint of the costs of the various tests.
I know that it is impossible to give exact costings, but some very general indication and comparison with other tests (e.g. the various acid phosphatases) seems essential to me for the rational selection of tests in the conditions of today.
