At Accredited Drug Testing, we offer extensive hair follicle drug testing services in Castor, Louisiana. Our expertise is in hair and alcohol testing, with a widespread network of testing centers across all cities Nationwide ready to carry out hair assessments. For most analyses, you need 1.5 to 2 inches of hair from your head or body. Hair tests can be tailored to identify drugs, alcohol/ETG, or other specific testing parameters.
In recent times, hair follicle drug tests have become increasingly prevalent for drug screening. Employers, courts, and substance misuse counselors now often favor hair tests over conventional urine tests. These tests are employed in zero-tolerance workplaces, judicial proceedings, and during probation check-ins. The main advantage of hair follicle drug testing is the extended detection period for substances, usually up to 90 days, collected under supervision and resistant to tampering. Yet, when evaluating recent drug use within five days, urine tests remain most accurate.

Hair testing has evolved into a crucial method for detecting drug and alcohol consumption. It captures a long-term usage history by encapsulating biomarkers within the strands of growing hair. By collecting hair near the scalp, it can reveal a drug or alcohol pattern up to a 3-month period. The collection of hair is straightforward, hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches from approximately 200 hair strands (comparable to a #2 pencil size) near the scalp will yield about 100mg of hair, which is optimal for preliminary testing and verification. For EtG, added tests, and/or analyses surpassing 10 panels, 150mg of the sample is advised. Measuring the sample on a jeweler's scale is recommended. If scalp hair isn’t accessible, an equivalent amount of body hair can be collected. When we reference head hair, it pertains only to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test outcomes encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into a lab’s system. This process involves ensuring the proper sealing and shipment of the sample, creating a random LAN (Laboratory Accessioning Number), and fulfilling any supplemental data requirements outside an electronic chain of custody system.
Screening provides a preliminary rapid assessment for drugs of abuse. While it’s a cost-efficient approach for negating drug presence in most samples, to be valid in legal contexts, a positive screen must be verified. Any samples indicating potential positivity in Screening must undergo secondary confirmation.
For samples presumed positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. This step involves isolating drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which establishes hair drug testing as the most complex method to perform.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo washing prior to confirmation when necessary. The overarching lab process from Accessioning to Confirmation is evaluated under the guidelines of the CAP (College of American Pathologists) Hair designation and adheres to the ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis focuses on the hair strand rather than the scalp's hair follicle.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
