Drug Screening
Employment, Pre-Employment

In order for the drug testing task to be successful, certain protocols such as information gathering and specimen collection have to be followed. A representative from Toxicology Associates, Inc. will assist you with these important steps which are necessary for accurate reporting of drug test results.

1. Information Gathering

A Chain of Custody/Drug Consent Release
form will be filled out with the donor's name, id number, medications, etc. Proper identification such as a driver's license is required. See Chain of Custody/Drug Consent Release form.

2. Specimen Collection

Collection of a sample can be done at our laboratory or at your work site. Toxicology Associates, Inc. will provide all necessary materials for sample collection.

A sealed drug free urine container will be given to the donor for urine collection. Thereafter, the temperature (must be 90 oF or above) will be noted within 4 min. Temperatures below 90 oF indicate substances (i.e. water, salt, etc.) were added to give an inaccurate result. To avoid tampering of the sample, the donor will initialize and date the seal, which will be placed over the urine container.

Once the sample is received in our laboratory, we will note other characteristics of the sample such as color, odor and pH of the urine, before proceeding with analysis.

3. Delivery/Transport of Specimen


Local - Toxicology Associates, will provide courier service at No extra charge. For out of town, delivery through Airborne Express or UPS will also be provided at minimal charge.

Stats (Emergency)

There will be an additional Stat fee of $65.00 per sample.

4. Testing of the sample

We will screen for drugs classified under DEA Controlled Substances. These include classes of drugs such as Marijuana, Cocaine, Opiates, Barbiturates, Benzodiazepines, Methadone, Meperidine, PCP, Amphetamines, and Propoxyphene that are commonly used and abused today.

5. Methodology of Drug Testing

All employment/pre-employment drug testing will be done by AlphaTox method. This is the only to catch those who are trying to beat the drug test system.


According to State of Ohio law, any positive result must be confirmed by a different method preferably by Gas Chromatograph/Mass Spectrometry (GC/MS). This assures 100% confidence of results at all times. GC/MS is highly accurate and sensitive. It is the only federally approved form of confirmation.

6. Turn-Around Time

Routines - within 24 hours
Stats - between 1.5 - 2 hours. This will vary depending on the complexity and already existing critical emergency case.
