Accredited Drug Testing offers comprehensive hair follicle drug assessments in China, Texas. For anyone requiring a hair drug or alcohol evaluation, Accredited Drug Testing is proficient in hair analyses and operates facilities across all cities nationwide equipped for hair assessments. Typically, a hair length of 1.5 to 2 inches from the crown or other body parts is necessary for testing purposes. These analyses can detect drugs, alcohol/ETG, or support other tailored options.
Over recent years, hair follicle drug testing has increasingly been incorporated into drug screening protocols. A growing number of employers, judicial bodies, and substance abuse experts are opting for hair-based evaluations over traditional urine assessments. Those with zero-tolerance policies often rely on hair follicle tests, including employers, courts, and probation services. The standout advantage is its extended detection timeline, spanning up to 90 days, with a direct supervision collection method, making tampering nearly impossible. However, for identifying drug use within the recent 5-day window, urine tests remain the most reliable option.

Hair analysis has increasingly become recognized as an effective method for identifying drug and alcohol consumption. This is due to hair's ability to encapsulate biomarkers related to alcohol and drugs within the strands as they grow. A sample taken near the scalp can disclose up to a three-month history of alcohol and drug usage. It’s straightforward to procure, relatively resistant to tampering, and easy to transport.
A hair sample measuring 1.5 inches in length and comprising approximately 200 strands (comparable to a #2 pencil in thickness) near the scalp equates to around 100mg of hair, which is optimal for both screening and validation. For EtG, add-ons, or panels exceeding 10 drugs, 150mg is suggested. We advise using a jeweler’s scale to weigh the specimen. When scalp hair is unavailable, a similar quantity of body hair may be used. Note that 'head hair' refers specifically to scalp hair, whereas 'body hair' encompasses all other types (e.g., facial, axillary).
Process Overview
The processing of a drug test outcome in a laboratory involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into a laboratory's infrastructure. This incorporates checking the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody system.
Screening consists of a preliminary assessment for drug abuse. Although Screening is a cost-efficient means of dismissing drug usage for most samples, a positive screening necessitates confirmation to be valid in a legal setting. Any samples testing presumptively positive during Screening require a secondary confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations than in other approaches (like urine or oral fluid), which contributes to hair drug testing being the most challenging approach to execute.
Confirmation of any positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if needed. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although often labeled as "hair follicle tests", the analysis is performed on the strand of hair, not on the follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
