Abstract:- Recently there has been considerable interest in the use of hair as an index to the status of essential trace metal metabolism in the body particularly zinc. In many respects hair is ideal for such use. The sample can be readily obtained without pain or trauma for the patient, is easily collected and requires no special equipment or storage. The concentration of the metal in the hair is high and large quantities of samples are easily available, making the task of the analyst easier. Further, hair does not readily deteriorate, and can be stored until it is convenient to perform the analysis. In this study we have established a Quality Control (QC) method for the day to day measurement of zinc in human hair making use of a pool of human hair collected from both men and women. The QC thus prepared shows good stability for a period of six months. The intra and inter assay precision (%CV) using such a hair QC were 3.6 and 5.9 respectively and both values are within acceptable limits.
