Two cases are reported in which symptomatic lead poisoning coincided with normal haemoglobin concentrations and blood lead levels below 80 μg/100 ml. Urinary coproporphyrins and amino laevulinic acid concentrations were elevated. These latter tests are useful for confirmation of clinical diagnoses and for the screening of industrial lead workers.
