Asbestos is a health hazard in many homes, offices and schools. Exposure to asbestos can cause lung cancer. An estimated 20,000 people will die each year for the next 30 years from asbestos exposure. The Prolab® do-it-yourself asbestos test kit offers a laboratory test which identifies asbestos fibers to as little as 1% content by weight using polarized light microscopy. Laboratory results within 7 days. Express service is available for an additional fee.
