Forensic Toxicology



Forensic toxicology is an important tool to a lawyer that provides an opportunity to determine the identity and/or quantity of an alleged substance, or perhaps verify that the found substance is accurate, and a true representation of their findings. 

Process of Having An Analyzed substance re-analyze

1. Court Order Issuance - A court order to issue an independent laboratory analysis of a disputed result or result verification  from the original sample must be requested by the defending attorney.  This should outline the defendants name, case number, the sample(s) with its accompanying number if available, the analyzing laboratory, etc.  Once in place, the court order document can be submitted to our laboratory through mail at Toxicology Associates, Inc., 999 Bethel Rd., Columbus, Ohio 43214, facsimile at  614-459-2409, or through email at

2. Specimen (Evidence) Transport - The contact person and their phone number having custody of the evidence must also be made available to us.  We will contact the agency to coordinate the transport of the evidence of interest to our lab.   It is the agency's discretion as to how they wished to have the evidence transported.  This can be done personally, overnight delivery through FedEx, for example, or delivery through one of our personnel or couriers.  In addition, a chain of custody will be maintained at all times.

Payment - We would require payment in full in the forms of cash, check, credit card, or money order before service is rendered.  For court appointed cases , please have the approved funds indicated on the court order.  Once approved, disbursement of funds must be made, before any services are rendered. 

4. Analysis and Reporting of Results - Analysis of a sample(s) is highly technical and requires highly trained personnel to run the test.  Additionally, the latest scientific instruments such as the Gas Chromatograph Mass Spectrometry (GC/MS) assures highest quality lab results at all times.

For Out of State Analysis

If the case is in a state other than Ohio, the sample(s) can still re-analyzed.  This is true especially if the found substance identity (i.e. Cocaine, Marijuana, etc.) needs to be verified.  Thus, a Qualitative (identification) re-analysis of a substance(s) for the most part would be helpful.  The organization/institution or perhaps the prosecuting attorney will agree to have a portion if not all of the sample evidence be submitted for re-analysis.  If it is agreed that a portion of the sample evidence can be submitted for testing, the following are specimen requirem

a. Qualitative - Identification Analysis (see below for prices)

    a. Vegetative (i.e. Marijuana, Ergot, etc.) - 0.10 gram min., ideal 1.0 gram
    b. Solid (i.e. crack cocaine, etc.) - 10 mg min., ideal; 0.10 gram
    c. Powder (i.e. cocaine, heroin, etc.) - 50 mg, min, ideal; 0.10 gram
    d. Liquid (i.e. blood, serum, urine, etc.) - 0.125 ml whole blood, ideal; 0.50 ml
                                                               5.0 ml min urine
                                                               5.0 ml min other liquids

Place sample in a tightly sealed and secured container, that is also labeled with the subjects name, identifying numbers or codes, and initial of the technician who prepared that aliquot (portioning of the

Submit the sample(s) along with a chain of custody form to our laboratory at Toxicology Associates, Inc., 999 Bethel Road, Columbus, OH 43214.

b. Re-Weighing of Evidence Sample(s)

If the evidence needs to be re-weighed for verification, challenge, etc. it could also be done, in which we will have to travel to have it weighed.  As for flight reservation, car rental, etc. these can be done either by your organization,  or we can do it for you.  If you opt for the former, please submit the itinerary through mail, email, or facsimile.  Likewise, if you choose the latter, we will notify you of the additional costs. In any case, please give us a lead time of at least 2 weeks to make sure there are no time conflicts.

Blood/Urine Drugs of Abuse (DAU) Analysis

The DAU screen is a qualitative measurement of drugs in a sample. It is a quick way to determine whether or not a person is using or abusing drugs. Below are the most common drugs that people use or abuse. The DAU drug screen is available only as individual testing or a 10 panel DAU.  See below for fees.

Drugs of Abuse Fee Schedule

a. Single Drug Analysis - Fees for Urine Specimen ONLY

Drug Fee Drug Fee
Amphetamines $175.00 Heroin $195.00
Benzodiazepines $225.00 Flunitrazepam (Roypnol) $175.00
Cocaine $215.00 Meperidine $165.00
Fentanyl $285.00 Opiates (Codiene, Morphine, Heroin, Oxycodone) $245.00
Gammahydroxybutyrate (GHB) $235.00 Oxycodone $185.00

b. Multiple Drug Analysis - price per sample

1. 5 Panel DAU (any 5 drugs above) - $550.00 (urine), $625.00 (blood)
2. 7 Panel DAU (any 7 drugs above) - $625.00 (urine), $740.00 (blood)

3. All Ten Drugs (10 Panel DAU) above list - $885.00 (urine), $945.00 (blood)

Specimen Requirements  

Urine: 30 ml random urine (5 ml min). Addition of Sodium Fluoride preservative is required.


Method of analysis include Gas Chromatograph, Gas Chromatograph Mass Spectrometry (GC/MS) ONLY. This is highly accurate and sensitive that produces results with 100 confidence.  Additionally, it is highly recognize in court as the "Gold" standard in analytical testing of drug compounds.

Alcohol (Ethanol Analysis)

Ethyl Alcohol or Ethanol is an organic compound found in alcoholic beverages such as beer, liquor or wine.  The of analysis of Ethanol is ideal for DUI/DWI case or suspected alcohol consumption, whereby alcohol analysis is required that may have legal implications. The specimen of whole blood is usually preferred as this gives the true level of alcohol. Serum may also be used. However, the alcohol level is between 16%-18% higher than whole blood. A urine specimen is also acceptable.

1. Whole Blood: 5 ml whole blood.  Use lavender top tube with Sodium Fluoride (NaF) preservative.
2. Serum or Urine; 3.0 ml serum or 15 ml urine with Sodium Fluoride preservative.

FEE  (Blood, serum, or urine) - $345.00 per sample per specimen type (blood, serum, or urine.

Glucose Analysis - $275.00 per sample.  Highly recommended.  Why test for glucose?  Glucose is a sugar that is broken down to ethanol alcohol, that can contribute to the overall concentration of Blood Alcohol (BAC).

Method: Gas Chromatograph Flame-Ionization Detection (GC-FID).

Quantitative Weight Measurement of Drug(s)

     Often times, illegal substances of Cocaine, Marijuana, and others are found during search and seizure or simply through a routine traffic violation stop. 

     To verify that the weight of a found substance (i.e. Cocaine, Marijuana, etc.), re-weighing is an important task.   In doing this, a qualitative and/or physical weight measurement of the alleged substance can be done.  If the substance has already been identified, physical weight measurement or re-weighing is usually done.
