Drug Detection Technology offers a full line-up of Laboratory Confirmation Drug Testing products and services that provide the essential information you need to make informed decisions.
Laboratory Confirmation Drug Testing is able to definitively detect individual compounds by matching them to a commercially prepared reference standard using one of the following:
- GC-MS (Gas Chromatography – Mass Spectrometry)
- GC-MS/MS (Gas Chromatography – Tandem Mass Spectrometry)
- LC-MS/MS (Liquid Chromatography – Tandem Mass Spectrometry)
Confirmation tests provide qualitative results of drugs and/or drug metabolites present in the sample. Drugs are rapidly metabolised in the body and aids with detection of metabolites that indicates drug use by the donor. Sometimes it is only the metabolites that are positive in a confirmation test. For example, heroin is rapidly broken down to 6-monoacetylmorphine (6-MAM) and cocaine is rapidly broken down to benzoylecgonine. Detection of these metabolites demonstrates use of heroin and cocaine respectively. Only a confirmation test would allow the laboratory to make the distinction between illicit, prescription medicines or over the counter medication.
Confirmation results are expressed as positive or negative and are legally defensible.
Laboratory Based Oral Fluid (Saliva) Testing
With oral fluid testing, saliva samples are tested for parent drugs and their metabolites. An absorbent collection device is placed in the mouth and the saliva collected is screened for drugs of abuse in the laboratory. Samples are checked to verify the saliva is human. Oral Fluid offers a substance detection time frame similar to urine and blood testing, but oral fluid samples do not require special collection facilities or working with hazardous bodily fluids.
It is important to note that our oral fluid testing is a completely laboratory based process.
While some instant oral fluid collection devices may be available, they are often not properly FDA-cleared and lack the sensitivity required to detect usage of certain drug classes. It is for these reasons that a laboratory-based process must be used in order to secure valid results.
Hair Drug Testing
Recently, hair testing has come to be seen as a powerful tool for the detection of drug and alcohol abuse. Hair serves as a repository for drugs, metabolites, vitamins, heavy metals and other substances delivered by the blood to the hair root. These substances are principally deposited in the internal portion of the hair, known as the cortex. This keratinized cortex comprises the bulk of the hair mass.The outside covering of the hair, known as the cuticle, generally protects the cortex and helps make the hair an extremely tough and durable natural fiber.
Unlike blood and urine, hair represents a more lengthy record of drug exposure. The average rate of growth for head hair is about 1.3 cm (centimeter) per month, so a 3.9 cm length of hair represents a "snapshot" of the subject's drug use in the last 3 months or 90 days.
EtG Hair Alcohol Testing
A hair alcohol test that measures average alcohol consumption over a period of approximately three months, indicates the level of alcohol use during that time period, and can provide a behavioral indication of excessive use.
EtG is a trace metabolite of ethanol and is considered a direct alcohol biomarker. Alcohol is not deposited directly into the hair – it breaks down into ethanol byproducts. This marker cannot originate from other pathological sources.
EtG testing applies to the determination of chronic excessive alcohol consumption only. This consensus is not applicable for determination of abstinence from alcohol.
EtG is water soluble and can be detected in various body fluids, hair and autopsy samples.
We require 100 mg of head hair for the alcohol test. The sample may be taken from the upper crest, the lower crest, or from either the right or left temporal area on the head. 3.9 cm is the minimum amount of hair required.
Fingernail Drug and EtG (Alcohol) Testing
Highly stable, simple to collect, and easy to ship and store, fingernails provide a test sample that is at the cutting edge of drug and alcohol testing. Fingernails are made up of keratin, the same material that hair is made of. As the nail grows, substances can pass from the blood vessels below the nail into the keratin fibers where they become trapped.
Fingernails are four times thicker than the typical strand of hair and often capture more of a substance than hair can. Biomarkers become locked in keratin fibers along the entire length of the nail, and can be detected up to 3-6 months after drug or alcohol abuse.
PEth Testing Dried Blood Spots
Dried blood spot collection is the fastest, most convenient way to test for phosphatidylethanol (PEth). Phosphatidylethanol (PEth) is created in red blood cells where it exists as part of the cell membrane. Research suggests a PEth test can differentiate between incidental exposure (hand sanitizer use, etc.) and the intentional use of ethanol.
PEth is an abnormal phospholipid formed in red blood cells following alcohol exposure. PEth in blood exists as a component of the red cell membrane. PEth is stored in the cell membrane and can be extracted from dried blood spot specimens and measured to identify alcohol exposure.
PEth is a mid to long-term alcohol biomarker, and a positive result (measuring phosphatidylethanol species 16:0/18:1) is an indication of alcohol exposure during the 2-3 weeks prior to sample collection.
The sample amount is 5 dried blood spots from a finger puncture or 5 ml of blood from a standard blood draw using anticoagulation tube collection.
Anabolic Steroid Urine Testing
Over the past decade, anabolic steroid abuse and the use of other performance-enhancing drugs has become a national concern! Androgenic-anabolic steroids and other performance-enhancing drugs are banned by major amateur and professional sports authorities. Individuals of various ages abuse steroids, but it is the abuse among high school students which is a serious problem!
