Accredited Drug Testing offers comprehensive hair follicle drug examinations in Berkeley, Florida. Specializing in hair and alcohol tests, we have centers across the nation ready to assist. Typically, 1.5 to 2 inches of hair from the head or body is required. These samples can be tested for drugs, alcohol/ETG, or tailored options.
Recently, hair follicle tests have become more common in drug testing. Employers, courts, and substance abuse experts now prefer them over traditional urine tests. Hair tests are favored by strict no-drug-use workplaces, courts, and probation requirements. Their key benefit is a longer detection window, up to 90 days, observed during collection, and hard to tamper with. For the last 5 days, urine tests remain more precise.

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. The hair encapsulates markers within the fibers of the strand as it grows, offering a comprehensive history of substance use. Sampling near the scalp, hair can reveal usage patterns for up to three months for both alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient for transportation.
Collecting a 1.5-inch segment comprising around 200 hair strands (resembling a #2 pencil) from where they emerge at the scalp, provides 100mg—a suitable quantity for both screening and verification. For extensive tests such as EtG, add-ons, or panels exceeding 10, 150mg of the sample is advisable. Utilizing a jeweler’s scale for measurement is prudent. Should scalp hair be lacking, an equivalent amount from body hair is acceptable. Note that 'head hair' specifically refers to 'scalp hair', while 'body hair' includes all other hair types (like facial, axillary, etc.).
Process Overview
The four pivotal stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory’s records, ensuring it was properly sealed and transported, and is assigned a distinct LAN (Laboratory Accessioning Number), while any additional entries not covered by an electronic chain of custody system are completed.
Screening provides a preliminary assessment for substance abuse. It serves as a cost-efficient method to eliminate drug usage in most cases; however, any positive findings need supplementary confirmation for legal admissibility. Presumptive positives identified in Screening must be further confirmed.
In cases of presumptive positives during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are separated from the hair at notably lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex procedure to execute.
Any positive outcomes from Screening are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Required pre-confirmation washing of samples that preliminarily test positive is conducted. The full procedure, spanning Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and compliance with 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.
