In Carlsbad, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Specializing in hair-based tests for drugs or alcohol, we have centers in every city nationwide ready to perform the procedure. Typically requiring 1.5 to 2 inches of hair from the scalp or body, these tests can detect drugs, alcohol/ETG, or other specific substances.
Recently, hair follicle drug tests have gained popularity over traditional methods. Many employers, courts, and substance abuse experts now prefer them to urine tests. Used by zero-tolerance employers, legal bodies, and probation officers, the main advantage is its 90-day detection period, collected under observation and hard to tamper with. However, for recent drug use within 5 days, urine tests remain the standard.

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by embedding biomarkers in the strands as they develop. When harvested near the scalp, hair can reveal drug and alcohol presence over a detection span of up to three months. It is straightforward to collect, challenging to tamper with, and facile to transport.
A 1.5-inch segment consisting of about 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, representing the optimal quantity for screening and confirmation. For EtG, additional tests, or assessments beyond 10 panels, 150mg of hair is advised. We suggest measuring the sample on a jeweler’s scale. Should scalp hair be unattainable, a comparable quantity of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes the four key steps of Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the initial processing of a sample into a lab’s system is conducted. This step involves confirming the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and completing any further data input not supplied by an electronic chain of custody system.
Screening involves a preliminary rapid inspection for abused drugs. While it’s a cost-effective approach to eliminate drug usage for most samples, a positive screen must be corroborated to be legally valid. Any samples that yield a presumable positive in the Screening phase need confirmation via a secondary test.
If Screening indicates a presumable positive result, additional hair is extracted from the initial collection and prepped for Extraction. Drugs are pulled from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. From Accessioning to Confirmation, the entire lab process is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
