The Drug Chemistry Section is responsible for identifying substances scheduled by Ohio Administrative Code section 4729:9-1. Using analytical techniques such as infrared spectroscopy and mass spectrometry, the section routinely analyzes more than 10,000 items a year.
The Drug Chemistry Section conducts qualitative analyses on suspected drugs of abuse using both a presumptive analytical technique to determine the likely identity of a substance and a confirmatory technique such as infrared spectroscopy or mass spectrometry to conclusively determine the identity of an unknown compound. In addition, the section performs quantitative analyses on submissions of suspected cannabis and cannabis concentrates to determine the percentage by weight of tetrahydrocannabinol present. Results are only reported for compounds that both presumptively and confirmatively test positive.
The drugs of abuse tested by the Drug Chemistry Section can belong to the following classes of drugs:
NOTE: The list of compounds above is not an all-inclusive list of the compounds that are identified by the Drug Chemistry section. Questions about specific drugs should be forwarded to the laboratory.
All reported results from the Drug Chemistry Section will indicate the identity, the weight if not a residue, and the Ohio Administrative Code schedule of the compound. When applicable, the dosage of the pharmaceutical product will be reported. If a quantitative result for cannabis compounds is being reported, it will be reported as a percent by weight of total THC (a combination of delta-9-tetrahydrocannabinol and tetrahydrocannabinolic acid). ...

All testing methods used by the Drug Chemistry Section meet the requirements established by the ANSI National Accreditation Board (ANAB) for forensic laboratories.
The Ohio State Highway Patrol Drug Chemistry Section utilizes Best Evidence Selected for Testing (BEST) for internal customers only. BEST allows the analysis of the highest penalty item in a case, excludes the lower penalty items, and reduces the turnaround time. If testing is needed on the excluded items, an email should be sent to the laboratory. The excluded items will be tested upon receipt of the email.
Certain submissions have special considerations. Please package items properly to ensure the item will be accepted for testing. ... Read more
Items not properly sealed will need to be corrected before they are accepted and logged into the laboratory.
The Toxicology Section provides laboratory analyses of biological specimens (urine, blood, serum and vitreous humor) to determine the presence of both alcohol and drugs. The laboratory findings can then be used to assist law enforcement and legal communities to explain impairment and/or human performance associated with arrests, crashes and fatalities. The Toxicology Section currently receives and completes in excess of 10,000 cases annually.
Qualitative Analysis: Two (2) dissimilar tests, a presumptive test and a confirmation test, are conducted to conclude the presence or absence of the drugs included in the laboratory’s test menu. The laboratory report will reflect the presence of a drug as Positive. (ex. Tramadol Positive) Positive findings are reported ONLY if both dissimilar tests conducted support the same conclusion.
Quantitative Analysis: Two (2) dissimilar tests, a presumptive test and a confirmation test, are conducted to conclude the presence or absence of the drugs included in the laboratory’s test menu. Positive results are quantitatively measured to reflect the amount of drug present. The laboratory report will reflect the name of the drug present and the amount of drug present. A calculated range of uncertainty will accompany all quantitative results. (ex. Cocaine 535.20 ng/mL +/- 37.46 ng/mL). Positive findings are reported ONLY if both dissimilar tests conducted support the same conclusion.
The test menu for this laboratory includes both therapeutic drugs and drugs of abuse. Some of the included drugs and drug classes are:
For a full list of the drugs included in the test menu for both blood and urine samples, including cutoff levels, please see the Blood and Urine Drug Panel Information quick link.
The laboratory routinely conducts quantitative analyses for the presence of ethanol (drinking alcohol) within biological specimens utilizing headspace gas chromatography. Non-biological specimens such as beverages may be analyzed for the presence of ethanol as well.
This laboratory follows strict guidelines and validated methods to produce legally defensible results for all analyses conducted. The methods utilized meet the standards established by the ANSI National Accreditation Board (ANAB) for forensic laboratories, as well as the guidelines set forth in the Ohio Administrative Code.This laboratory does not currently have the methodology to conduct testing for the following in biological specimens:
Samples requiring these types of analyses should not be sent to this laboratory.
If possible, submit both urine and blood; both have advantages. ... Read more
