1. Administration. A saliva test involves the use of a swab to collect the specimen from the mouth and gums. The test does not require a restroom and the procedure can be administered in the presence of the administrator. With urine tests, the specimen is collected by the individual and is conducted in privacy. Most urine cups contain a temperature strip to ensure authentication.
2. Results. According to the Journal of Analytical Toxicology (Vol.25, 2002), saliva testing yields significantly more positive test results every year in the areas of THC (Marijuana), Cocaine, and Amphetamines. In the areas of Opiates and PCP, the number of positive results is similar for both urine and saliva.
3. Minimum Detection Period. Urine tests detect the major metabolite of the drug, while saliva tests detect the parent compound of the drug (this compound is the same that is found in blood.) Typically, it takes about 4 hours for a drug to become detectable in urine, while drugs can be detected almost immediately in saliva, as soon as the individual begins to feel the effects of the drug. For this reason, many companies find saliva testing ideal for post-accident investigations.
4. Maximum Detection Period. There are many factors that affect the window of detection, such as method and amount ingested. Saliva has shown positive results up to 3 days after ingestion. Urine testing has shown positive results up to 7 days after ingestion. For this reason, many companies find urine testing to be ideal for pre-employment screening.
5. Cost. Because urine is still the standard of in-house drug testing, it continues to be the most affordable method. Depending on the test, saliva testing can be twice as expensive compared to urine testing. Many of our clients still choose saliva testing because they feel it is less intrusive.

It is always important to collect a sufficient amount of specimen in case of a non-negative result. Most confirmation laboratories require a minimum of 15mL of specimen but prefer 30mL for urine testing. For saliva, it is 2mL. |
