Colorado Drug Probation Testing – Oral Swab Drug Tests – Are They Accurate?

Colorado Drug Probation Testing – Oral Swab Drug Tests – Are They Accurate?

Colorado Probation Criminal Drug Testing – Oral Swab Drug Tests – Are They Accurate? – The decision to miss a UA or refuse a chemical test for drugs while on probation can sometimes be remedied by immediately taking a voluntary drug test at a private lab. The oral swab test for drugs – including marijuana – provides a quick and reliable alternative to the standard UA and it is much less humiliating.

A “saliva” test is an alternative method to test for drugs. It is a “noninvasive” collection of a saliva which is easy to perform and can be taken under the closest supervision.

The presence of certain “analytes” in saliva gives a more accurate indication of recent use of certain drugs (such as marijuana) than urine, therefore there is a higher probability that a subject recently feeling experiencing the pharmacological effects of a drug will be detected – revealed at the time of the sampling.

Saliva tests react to the most common drugs monitored on probation:

  • marijuana,
  • cocaine,
  • opiates,
  • amphetamines / meth-amphetamines, and
  • PCP.

As noted above, oral fluid drug detection is considered a better type of specimen than urine for detecting recent use.

Oral fluid testing detects drugs immediately after the most recent use and up to 4 days later. When compared to more conventional drug testing with urine – the latter test is unable to detect usage in the first four hours after use.

However, equally important is the fact that a saliva (oral fluid-based) drug test will not only detect very recent use it can also detect use within the previous few days. Saliva drug tests are also difficult to tamper with and, like urine tests, are performed “on-site.”

Saliva tests provide results similar to the gold standard of drug tests  – the blood test – but are much less invasive.

Over the last 10 years procedures for all types of drug testing have advanced on several fronts. Alternative specimens to blood and urine have advanced the state of forensic toxicology. The use of specimens taken from such sources as hair, perspiration and oral fluid provide non-invasive alternatives to urine and blood with advantages and disadvantages to each.

With A Saliva Drug Test Fake Urine And Dilution Issues Are Removed As Possible Issues

I have written on the issues surrounding trying to “beat” the UA (urine testing) in Colorado before. UA’s provide opportunities to get into trouble by attempts  to “adulterate” the specimen by trying to substitute fake urine or by drinking large amounts of water. This is not possible with oral fluid specimens.

Because compounds that are present in blood are almost always present in their saliva, saliva tests can measure the “parent compound” of that drug. The parent compound of a drug is the “psychoactive element” of a drug. The presence of the parent compound of a drug in saliva indicates that the drug has entered the blood stream.

The detection of higher levels of the parent compound in saliva indicates higher levels of the drug contained within the body. Therefore saliva levels can also be used to measure impairment. Saliva tests measure the parent compound and urinalysis do not.

Urinalysis only measure the by-product compounds of drugs known as “metabolites.” Metabolites do not correspond with impairment levels which is why Colorado uses only blood tests in Driving Under The Influence Of Drugs testing.

Understanding Oral Fluid Drug Testing In Colorado – How The Test Is Actually Administered

The Oral Fluid Drug Testing Procedure

The testing device is a sterile, absorbent pad attached to the end of an applicator handle, much like a toothbrush handle.

The pad is placed inside the lower part of person’s mouth, between their teeth and gums on one side.

The person holds it in their mouth for 2 to 5 minutes until it is saturated with saliva.

In most cases the pad is tested immediately on-site and negative screen test results can be provided the same day.

Two Stages To A “Hot” Result – When The Test Is Presumptively Positive – The Need For Confirmation

If there is a positive – or “non-negative” result – when you take a drug test – no matter what that test is – a second stage of the process requires a confirming test by a different procedure be completed to make certain the first result was accurate, that is, the “positive” non-negative specimen must be sent to a laboratory for confirmation of the suspected result.

The confirmation of so called “non-negative” results usually utilizes some form of gas chromatography / mass spectrometry. The first stage noted above is called an “immunoassay screening” and does not provide an individual identification of the suspected drug. The second stage then is absolutely necessary to make certain the testing is completely accurate, either confirming and measuring the amount of the drug in the body or proving that the initial non-negative result was a “false positive.”

Saliva Tests And The Active Ingredient In Marijuana – THC

Saliva THC

As noted – what is in the blood, will usually be found in the saliva. Delta 9 THC is the parent compound of the active ingredient in marijuana. Levels that can be measured in saliva in the lab range from 0.5ng/mL and higher (1 ng/mL = 1 part per billion). Delta 9 THC has been measured in oral fluid up to 72 hours after smoking.

Compare – Urine THC

11 nor 9 carboxy THC is the major metabolite found in urine. Because urine excretion of THC does not decrease consistently – urine screenings may fluctuate between negative and positive during the detection window. Urine is routinely used to test for drugs of abuse such as the amphetamines, cocaine and metabolites, opioids such as morphine, methadone and heroin, and for cannabis.

Summary – An Early Detection Window

The advantage of oral fluid testing is it has the ability to detect drug use within the first few hours after use. This is a window of time that is not provided by urine test results.

Oral fluid testing can also detect most drugs such as THC from 1 to 4 days after last use. Next to blood, oral fluid testing is currently the best non-invasive testing method for both impairment and post- car accident testing.
