Sampling problems in the micro determination of blood lead.
Sampling tube and fingertip contamination were found to present potential problems in the collection of samples for micro blood lead analyses. Large differences between micro screening and macro confirming lead levels were frequently observed when the time between collection of the two samples was 1-2 weeks. The magnitude of these differences decreased as macro blood lead concentration increased and were apparently a result of episodic lead ingestion in the population.
