Abstract
Urinary delta-aminolaevulinic acid (delta-ALA) excretion was evaluated in random urine samples of 191 healthy children, aged 2-14 years, with blood lead levels < 0.8 mumol/l (mean +/- SD: 0.34 +/- 0.13), erythrocyte zinc-protoporphyrin < 70 mumol/mol haem (mean +/- SD: 50.4 +/- 8.0) and blood haemoglobin > 6.8 mmol/l (mean +/- SD: 8.2 +/- 0.5). It was found that uncorrected delta-ALA concentration and delta-ALA/creatinine ratio are age-dependent, whereas the ratio of delta-ALA/logarithm of creatinine concentration (mean +/- SD: 55.3 +/- 13.5 mumol/log mmol) is independent of age and sex. The authors recommend the use of this parameter for the assessment of delta-ALA excretion in random urine samples in children.
