About Us

Purity Laboratories, Inc. is an independent lab that focuses on both clinical and environmental testing. Purity has more than 45 years of experience in analytical testing and opened a clinical laboratory division in 2013.

Purity’s environmental laboratory division offers analytical testing of food, water and environmental products. It also has expanded capabilities for nutraceutical testing to address new Food and Drug Administration regulations for the nutritional supplement industry.

Purity’s clinical division provides doctors and patients with the ability to order Vitamin D dry blood spot testing kits. It plans to add 20-30 other clinical dry spot tests in 2014, particularly, specialized tests for those with sensitivities or chronic illnesses.


In August 2013 Purity moved to a 19,000 sq. ft. facility in Lake Oswego, Ore., in order to expand their scope of work. The lab was Clinical Laboratory Improvement Amendments (CLIA) certified as a high complexity laboratory in September 2013. Testing is conducted on state of the art equipment, including the most advanced and accurate mass spectrometry technology.
