Oral specimen collection device. Close-up of an oral specimen collection device being placed in a collection vial to preserve a sample of oral fluid. The collecting pad was held between the lower cheek and gum for two to five minutes to absorb oral fluid. This fluid has a different composition to saliva. The pad is now being placed in a collection vial (bottom),which contains preservatives that stabilize the sample for up to 21 days. The sample is then transported to a laboratory for testing. Typical tests include screening for tobacco use and cocaine abuse. For a sequence showing the use of this device to take a sample,see images C025/4850 to C025/4853 | |
