Which of the following levels of BLL indicates the need for immediate medical removal?

Below 30 μg/dL
40 μg/dL - 50 μg/dL
50 μg/dL on two consecutive tests
60 μg/dL

The correct answer is: 50 μg/dL on two consecutive tests

The indication for immediate medical removal is based on the severity of lead exposure as measured by blood lead levels (BLL). A level of 50 μg/dL or higher, particularly when confirmed by two consecutive tests, signals that the individual's health may be at significant risk due to lead exposure. This threshold has been set to ensure prompt action is taken to prevent further exposure and to address potential health impacts associated with elevated lead levels. While other levels indicate concern and may warrant monitoring or interventions, the specific threshold for immediate action is set at 50 μg/dL on two occasions, as this strongly suggests that the individual is experiencing detrimental effects from lead and needs to be removed from sources of exposure quickly. This level aligns with guidelines established by health authorities to protect workers and prevent the harmful effects of lead toxicity. The significance of repeat testing also emphasizes the reliability of the measurement and the need for immediate preventative measures.
