Method development for the quantification of lead levels in whole blood sampled on Mitra^® with VAMS^® tips by...

Background: Lead is harmful for humans by having adverse effects on different biological systems. Venepuncture is the gold standard for blood lead level analysis, but this method has many flaws. The goal of this research was to develop and validate a more practical approach for blood sampling. Materials & methods: Mitra^® devices based on VAMS^® and inductively coupled plasma-MS/MS technologies were employed. Performance evaluation of the newly developed method was also performed by comparing it versus a commonly used method at the Centre de Toxicologie du Québec for blood lead level analysis. Results: Comparison showed no signs of significant difference between the two methods. Conclusion: VAMS may be a useful alternative sampling approach for further research on blood lead analysis and possibly for many other trace elements.
