What is the importance of the patented volume adequacy indicator?
A collector with a volume adequacy indicator is the only way to unambiguously meet SAMHSA guidelines (soon to become law) which spell out drug concentration cut-offs in oral fluids. SAMHSA mandates similar cut-offs for other specimens. However, when urine or blood is to be tested, variable volumes of sample can be collected but an exact volume is finally used in a test. Oral fluid collection devices use a collection pad placed in the subjects mouth. The entire pad is then transferred to a tube containing an extraction buffer(solution) and an aliquot(exact volume) is used in the test. It is obvious that If the amount of oral fluid on the collection pad is unknown, then the amount of diluted oral fluid used in the test is also unknown. A collection device with a volume adequacy indicator enables the laboratory to use a known volume for the test as is done for urine or blood.
