title: The assessment of zinc status by the zinc tolerance test in various groups of patients.
abstract: The zinc status of young and aged subjects, hypertensives, geriatric patients with leg ulcers and cancer patients has been determined by various means. Serum, saliva, urine and hair zinc were measured by atomic absorption spectrometry and no correlation was observed between the zinc levels in any of these differing matrices. The mean hair and salivary zinc level showed little variation between the differing groups of patients and provided little or no indication of zinc status. The results of the present experiment indicate that the zinc tolerance test, that is, an unequivocal rise in serum zinc following per oral administration of this metal, provides the best indication of zinc status.
