New York State has a separate and unique regulatory approval process for laboratory diagnostic testing. PeriRx is currently in the application process with our SaliMark™ OSCC test and is vigorously committed to pursuing this application approval. 



Welcome to PeriRx the leader in advanced saliva based diagnostic testing. Our test for the assessment of cancer risk in patients with oral lesions of concern is based on over a decade of scientific research supported by the National Institutes of Health. These markers have been independently validated by the National Cancer Institute – Early Detection Research Network and have also been studied in a number of medical universities worldwide. This test is requested at the discretion of your dentist or medical doctor to aid them in the decision on referral to a cancer specialist and in the subsequent decision on the need for an oral biopsy.
