Frequently Asked Questions

When can a DOT random alcohol test be administered?

A driver shall only be tested for alcohol while the driver is performing safety-sensitive functions, just before the driver is to perform safety-sensitive functions, or just after the driver has ceased performing such functions.

How do I know when I need to perform a DOT post-accident drug test, and how much time do I have to get it done?

For simplicity, we have created an online quiz that you can answer to quickly determine this.

Why does the same employee seem to be selected for random testing time after time?

Each driver selected for random alcohol and controlled substances testing under the selection process used, shall have an equal chance of being tested each time selections are made.

What is a consortium?

Consortium/Third party administrator (C/TPA) means a service agent that provides or coordinates one or more drug and/or alcohol testing services to DOT-regulated employers. C/TPAs typically provide or coordinate the provision of a number of such services and perform administrative tasks concerning the operation of the employers’ drug and alcohol testing programs. This term includes, but is not limited to, groups of employers who join together to administer, as a single entity, the DOT drug and alcohol testing programs of its members (e.g., having a combined random testing pool). C/TPAs are not “employers” for purposes of this part.

How much does it cost?

Cost will vary from site to site. Remember, you will get what you pay for. But, urine testing is by far the most cost-effective method for drug testing.

What is a “false positive”?

A false positive is a positive reading caused by another substance. Basically, a case of mistaken identity. RVOH uses a government approved lab with Medical Review Officer (MRO) approval on results. The chance for a false positive is very low. If, however, you do produce a positive result, you will be contacted by the MRO and asked to produce a prescription for medications that might have caused the result.

How valid is urine testing?

There are several markers that are used in testing the validity of the specimen. Creatine is always present in urine and measured at expected values. Specific Gravity also has expected values. These two markers are used to indicate diluted or substituted specimens. It is possible to denature substances by raising or lowering the pH of the sample. However, pH also has expected values. If any of these markers are out of the expected range, the sample is considered invalid.

Do masking agents work?

Products that were once used to throw off drug testing equipment are now detectable. The result is a failed drug test.

The ONLY guaranteed way to pass a drug test is NOT TO USE THE DRUGS being tested for.

How much urine is required for testing?

Testing using federal standards requires 45mL of urine. For non-federal testing, the amount of urine needed can vary.

All collections made at River Valley Occupational Health (RVOH) are made according to Department of Transportation (DOT) standards (45mL). This helps to ensure consistency of documentation and accuracy of results.

Why would I need a drug test?

There are many reasons for drug testing, such as:

Employment, Court Ordered, Child Custody, Parental Oversight or Medical Review.

Does external exposure to certain drugs, like marijuana smoke, affect tests?

No. Labs look for both parent & metabolites of drug use. Metabolites can only be present through direct consumption or intake into the body.

How much time is covered in a test?

Urine drug screening is an accurate and reliable way to determine casual drug use within a 72 hour window. However, there are many variables that affect the duration of a drug’s detectability. Things such as frequency of use, metabolism, drug half-life, physical condition, and hydration can increase or decrease a drug’s detectability.

What drugs are tested for in urine?

Testing urine can detect the presence of several different kinds of drugs. The 5 most common are: Cocaine, Marijuana, Opiates, Amphetamines, and Phencyclidine (PCP). Other drugs that can be detected are: Barbiturates, Benzodiazepine (Valium), Methadone, Propoxyphene (Darvocet), Methamphetamine, and MDMA (Ecstasy).

If you wish to test for a specific drug not listed, please call or email us, and we will let you know if it can be tested through urine or if another means of testing is required.

How long does it take to get drug screen results?

Urine drug screen results are reported within one business day, as long as the specimen is shipped to the lab the same day it is collected, and the specimen does not have to undergo further testing such as confirmation testing.

Hair test results are reported within 3 to 5 business days.

Any test results that have to undergo medical review for non-negative (positive) results will take an additional 1 to 3 business days. We are able to offer these MRO confirmed results faster than many companies in our line of business due to the fact that we have a Certified Medical Review Officer on staff.
