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.
