In Humboldt Hill, California, Accredited Drug Testing excels in offering comprehensive hair follicle drug assessments. For those requiring a hair-based drug or alcohol test, our expertise lies in hair evaluations, available at our nationwide testing facilities. Typically, having 1.5 to 2 inches of hair from the crown or body suffices. These evaluations address drugs, alcohol/ETG, along with bespoke hair testing options.
Lately, hair follicle drug evaluations have increasingly become standard in drug testing methods. A growing number of employers, judicial bodies, and Substance Abuse professionals are opting for hair tests over traditional urine evaluations. Employers with strict no-drug policies, courts, and probationers utilize these tests. Key benefits include an extended detection window, up to 90 days, with observed collections that are extremely difficult to manipulate. Nonetheless, for detecting very recent drug use within five days, urine tests remain the most precise option.

Hair tests are recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extended history of substance use by trapping biomarkers within the hair strand as it grows. When cut near the scalp, this method can reveal up to a three-month usage history for drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and convenient to send.
A 1.5-inch long sample of approximately 200 hair strands (comparable to a #2 pencil) from the scalp provides about 100mg of hair, which is optimal for both screening and verification. For EtG, additional tests, or panels exceeding 10, a sample weighing 150mg is advised. The hair should be measured on a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. "Head hair" means scalp hair specifically, whereas "body hair" includes other types such as facial or axillary hair.
Process Overview
The drug test laboratory procedure comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in incorporating a specimen into the laboratory's system. This step includes confirming that the sample has been properly sealed and dispatched, issuing a unique LAN (Laboratory Accessioning Number), and completing remaining data entry if not provided electronically.
Screening is a preliminary assessment to identify drugs of abuse. While it is an economical approach to eliminate drug consumption in most samples, a positive screening result requires confirmation for legal acceptability. Samples yielding a positive result during Screening need further verification.
For samples showing positive in Screening, additional hair is taken from the sample for Extraction. Here, drugs are extracted from hair at much lower levels compared to other mediums (like urine or oral fluid), making hair drug testing a challenging process.
The confirmation process for any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Positive samples undergo washing before confirmation if necessary. The full process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards compliance.
Advantages of hair drug testing:
Limitations:
Note: While often labeled as "hair follicle tests", the analysis is performed on the hair strand and not on the follicle beneath the scalp.

Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
