Lo et al have demonstrated convincingly that many characteristics of patients with primary HPT in Hong Kong mirror those seen in the Western world. Spanning the last 3 decades, more patients have been diagnosed as having less severe disease with fewer complications and symptoms. In contrast to many reports from Western countries, however, this change did not immediately follow the introduction of the blood chemistry multichannel autoanalyzer. In Hong Kong at least 7 years elapsed between the introduction of this technology and the notable rise in operative cases.
