A double blind clinical trial was conducted at Emory University Children’s Hospital in conjunction with the Georgia Department of Human Resources, Atlanta, GA and University of Massachusetts, Boston. More than 500 children between the ages of 6 months to 6 years were tested. The research results, soon to be published in The Journal of Clinical Toxicology, show that oral fluid is in all cases more reliable than any saliva test and in fact is as reliable as a venous blood test, because blood plasma is being collected in the oral fluid.
Oral Fluid Testing Laboratory, LLC PATENT
November 9, 2010, U.S. Patent Office issues OFT Labs: Patent #7829340
This patent clearly indicates that the results of the oral fluid testing procedures are as accurate as venous blood samples. Using OFT’s patented collection and testing procedures, the results comparing the non-invasive painless test versus an invasive painful blood test were 99.19% ACCURATE. Lead is measured in Ug/Dl, or micro-grams per deciliter [1 µg/dL = 5 ppm (parts per million)]. Simply put, the instrument is well within the capabilities of being accurate, even accounting for sample dilution and instrument error.
