Abstract
Objective The aim of this report is to propose a scheme for validation of an analytical technique according to ISO 17025. Material and methods According to ISO 17025, the fundamental parameters tested were: selectivity, calibration model, precision, accuracy, uncertainty of measurement, and analytical interference. Results A protocol has been developed that has been applied successfully to quantify zinc in serum by atomic absorption spectrometry. Conclusion It is demonstrated that our method is selective, linear, accurate, and precise, making it suitable for use in routine diagnostics.
