Take a look at this website that advertises the Oraline IV exclusively through the company called "Clinical Medical Marketing" on an FDA info website. I am not sure whether this is the genuine FDA site. But it "gives the impression" that it is already an FDA backed product by advertising it through this site. Check it out on this link - http://www.fdainfo.com/510k.html

Look for the "Drug Testing Supplies" link on the right hand side of the page, Find the Oraline IV product advertised under "Products under the menu section" (( http://www.cmm.com.au/Pages/saliva.html ))
