    Study on establishment of standardized measuring method for blood lead

    • Objective: To establish standardized measuring method for blood lead.Methods: Tungsren-ship atomic absorption spectrophotometry(GFAAS) was used to measuring blood lead level.According to the standard and regulation for blood lead detection from NCCLS and bureau of health,following performances were evaluated:inprecision,inaccuracy,method checking line,quantitative checking line,reportable range,cross contamination etc.Results: The blood lead level was highly consistent with adsorption value,the coefficient r=0.999 9(t=103.06,P<0.01);the inprecision,inaccuracy,methods test line and quantitative test line all meet the clinical need.The quantitative data could be provided when the blood lead level below 298 μg/L.Average cross contamination rates were 0.378%-0.394%.Experiment result fulfilled all demand for performance evaluation.Conclusions: Successfully establish measurement protocol with stable,repeatable and significant clinical development value.
