Abstract
Estimating uncertainty and quality of lead determination in blood.
The method for the direct determination of lead by AAS in whole human blood is presented. The previous experience and validation data are suggested as sources of performance information. The method recovery, sample recovery, homogeneity, precision and calibration were included to estimate measurement uncertainty compliant with ISO/IEC 17025 : 2005. The results of measurements using this method have uncertainty (52-23)% in the working range (70 – 700) μg.l-1.
