For determining exposure to lead, which specimen is appropriate?

Lead exposure is best assessed using whole blood because most circulating lead is bound to red blood cells and reflects recent exposure. Measuring lead in whole blood captures both the RBC-bound and dissolved fractions, giving a reliable indicator of body burden over recent weeks. Plasma or serum levels, by contrast, underestimate exposure since only a small fraction of lead is present in the plasma and does not reliably represent total body lead. Cerebrospinal fluid is not used for routine exposure assessment. Therefore, whole blood is the appropriate specimen for detecting lead exposure.
