No, the fluid in the Oragene device will dilute the saliva by an unknown amount and also has the potential to interfere with EIA, thus impeding the accurate measurement of analytes.
Yes, saliva collected for DNA analysis using SalivaBio or Salimetrics collection devices can be used for other analytes as well. DNA in whole saliva is obtained from the cell pellet after centrifugation. The supernatant can be used for testing other analytes. DNA is collected from the actual SalivaBio swabs after centrifugation, so the saliva in the swab storage tube can be used testing other analytes. Salimetrics recommends collecting the DNA material before testing for other analytes but it still possible to get the DNA sample after testing for other analytes provided that care is taken to prevent cross contamination during the testing phase.
