Orasure - enough sample collected?
Jul 15, 2001

Dr. Holodniy,

Ryan,

I had a quick question about Orasure. How much tissue sample or oral mucosal transudate (OMT) is required to make this test accurate? Is it possible to put the collection device in your mouth for 2-3 minutes but not collect enough sample to generate an accurate test result? (When one takes a standard blood test there is certainly enough visible specimen collected in a test tube!) Does the lab decide if there is enough specimen to generate an accurate result? How is it determined?

Response from Dr. Holodniy

That time is more than enough time collect enough oral fluid.
