Interleukin Genetics announces the introduction of PerioPredict, the Company’s next-generation version of the PSTs genetic risk test for periodontal disease. Like the original PST test, PerioPredict measures variations in the genes for Interleukin-1, a key mediator of inflammation, and identifies individuals who are at an increased risk for more severe periodontal (gum) disease. The improved sample collection device now uses a simple, easy-to-use cheek swab. PerioPredict can be performed by dentists or dental hygienists in about a minute during a routine exam or cleaning. The sample is then sent to Interleukin Genetics, a CLIA-certified genetics laboratory, for analysis. Test results are returned to the dentist in about 2 weeks.
