Before the test
Prevent external contamination during collection. Results require prompt occupational-health and workplace-control review; thresholds vary by jurisdiction.
Clinical interpretation
Laboratory results should be interpreted by a qualified professional using the correct reference interval, method, symptoms, history and other findings. A normal or abnormal value rarely confirms or excludes a condition by itself.
What the test is used for
Workers with relevant lead exposure and people with suspected environmental exposure, under jurisdiction-specific pathways.
How the test is performed
A contamination-controlled venous sample is analysed by atomic absorption or mass-spectrometric methods with traceable quality control.
Conditions and diseases considered
Used in lead exposure and poisoning assessment, which can affect nervous, blood, kidney, reproductive and cardiovascular systems.
Recommended further tests
Repeat venous lead level, zinc protoporphyrin, CBC, kidney tests and exposure investigation according to clinical and regulatory thresholds.
