Are Lead Checks more reliable than other spot test kits?
Lead Check kits are the only commercially available spot test kits in Australia. The company which manufactures Lead Check kits claims that when the US EPA tested the range of spot test kits available in the US, they found that Lead Check kits did not actually have any false negative results. However, the US EPA wrote their policy based on the results of testing the full range of spot kits. (see the attached ‘Federal Lead testing technologies studies confirm existing policy’) So the conclusion that spot tests have an unacceptable number of false positives and false negatives, may not relate to Lead Check kits. The Lead Advisory Service is currently seeking written confirmation from the manufacturer for the claim that Lead Checks do not give false negative results.
